A total of 35 groundwater monitoring wells, one artesian well, and four residential wells situated downgradient from the Site were sampled during the event. The water samples collected were submitted to the assigned laboratory for analysis in order to verify that constituents related to the Site are not present in the water samples. In addition, EPA and START V installed passive diffusion bags (PDBs) in 10 select monitoring wells in order to evaluate its potential use for future sampling events. 1.1 Site Location and Description The Site is a 1.5 square mile area located on the eastern end of St. Thomas, USVI within the upper Turpentine Run surface drainage basin in the Anna’s Retreat area. It is bounded by steep slopes and surrounding hills and lies slightly east of the city of Charlotte Amalie. There are two comingled groundwater contamination plumes at the Site. The higher concentration, northern and upgradient plume has a source near the Curriculum Center. The southern and downgradient plume has a source near the O’Henry Dry Cleaners. Chemicals of concern in groundwater are specific chlorinated volatile organic compounds (CVOCs). The downgradient wells sampled during this event include, 35 groundwater monitoring wells, one artesian well (RD-6), and four residential wells (SMITH, STEELE, DELEGARD, and TILLET). Refer to Attachment A, Figure 1: Site Location Map and Figure 2: Sampled Well Location Map (Oct. 2019). 1.2 Site History and Background The EPA identified several parties as potentially responsible for contributing to the contamination plumes. The largest contributor was a source at the Curriculum Center (former LAGA Building). This building was owned and operated by LAGA Textile Company, a clothing manufacturing plant, from 1969 to 1979 when it changed hands to Panex Co. until 1982. Extensive use of tetrachloroethene (PCE) occurred at the plant via an industrial size dry cleaning process that utilized PCE as dry cleaning solvent. Since 1982, the building has been used as a library, warehouse, and school offices. The remedy for the groundwater contamination consists of two groundwater treatment facilities (GWTF). GWTF #1 includes groundwater extraction and treatment by air stripping near the Curriculum Center source and previously also included soil vapor extraction (SVE). GWTF #2 includes groundwater extraction and air stripping at the downgradient end of the Curriculum Center plume just upgradient of the O’Henry plume. Operation of these systems were transferred from EPA to the Department of Planning and Natural Resources (DPNR) in 2014, but due to the impact of Hurricane Irma/Maria in 2017, the systems are now inoperable. Due to the extended shutdown of the Pump & Treatment (P&T) systems, EPA is concerned that the contaminant plume has extended downgradient and is potentially Tutu Wellfield Site Final Monitoring and Residential Well Sampling Report January 2020 2 impacting additional residential wells. Concurrent with this October 2019 groundwater sampling event, EPA evaluated the repair requirements for both P&T systems. Refer to Table 4: Historical Comparison of Groundwater Analytical Data, Prior to and After Hurricane Maria. On June 4, 2019, EPA and Weston Solutions, Inc., Removal Support Team 3 (RST 3), currently START V, sampled three residential wells, SMITH, STEELE, and DELEGARD, located downgradient from the Site. A total of four water samples, including one field duplicate, were collected from taps and faucets associated with the wells. Two water samples, including one field duplicate, were collected from SMITH well, one water sample each was collected from STEELE and DELEGARD wells. The water samples were analyzed by the assigned laboratory for target compound list (TCL) VOCs in order to verify that constituents related to the Site are not present in the residential well water. The analytical results of the water samples were compared with the EPA Maximum Contaminant Levels (MCLs) in accordance with the Drinking Water Standards and Health Advisories (DWSHA) dated March 2018. Based on the analytical results, TCL VOCs were either not detected or detected at concentrations well below the EPA MCLs. In addition, EPA conducted a reconnaissance to locate 70 groundwater monitoring wells associated to the Site. The coordinates, condition, headspace reading, water level, and depth of each monitoring well were documented as part of the reconnaissance. 2.0 Scope of Work The scope of work for the sampling event included the collection of water samples from 35 groundwater monitoring wells, one artesian well, and one residential well, using low-flow sampling method and the collection of water samples from taps and faucets associated with three residential wells. The water samples were submitted to the assigned laboratory for TCL VOCs analysis. In addition, all Site activities were noted in the Site log book and documented with digital photographs. In-addition, with the completion of the October 2019 groundwater sampling event, EPA and START V installed PDBs in 10 select monitoring wells in order to evaluate its potential use for future sampling events. 3.0 On-Site Personnel Name Affiliation Duties On-site Lou DiGuardia EPA, Region II On-Scene Coordinator Gezahegne Bushra EPA, Region II On-Scene Coordinator Gabriela Rodriguez Weston Solutions, Inc., START V Site Project Manager, Site Health &Safety, Sample Collection, QA/QC, and Sample Management Joel Siegel Weston Solutions, Inc., START V Sample Collection, GPS, and Sample Management Hector Rodríguez Weston Solutions, Inc., START V Sample Collection, GPS, and Sample Management Kathryn Donohue Weston Solutions, Inc., START V Sample Collection, GPS, and Sample Management EPA: U.S. Environmental Protection Agency START V: Superfund Technical Assessment Team V QA/QC: Quality Control/Quality Assurance GPS: Global Positioning System Tutu Wellfield Site Final Monitoring and Residential Well Sampling Report January 2020 3 4.0 Site Activities and Observations On September 30, 2019 through October 7, 2019, EPA On-Scene Coordinators (OSCs) and START V personnel sampled 35 groundwater monitoring wells, one artesian well (RD-6), and four residential wells (SMITH, STEELE, DELEGARD, and TILLET). Water samples were collected from the 35 monitoring wells and the one residential well (TILLET) using low flow sampling method, water samples were collected directly from taps and faucets associated with the remaining three residential wells (SMITH, STEELE, and DELEGARD), and groundwater sample was collected directly from the free flowing water of artesian well RD-6. Since RD-6 is an artesian well, purging was not necessary. A total of 44 water samples, including four field duplicates, were collected from all the wells for laboratory analysis. On October 7, 2019, EPA deployed PDBs in the following monitoring wells: RD-9, RD-13, MW- 15, RD-5, MW-25, DW-2, MW11D, RD-3, RD-8 and OU2-MW-2 in order to evaluate its potential use for future sampling events. Sampling of these PDBs is presently scheduled to occur in March 2020, when EPA and its Emergency and Rapid Response Services (ERRS) contractor performs repairs of the two treatment systems. Refer to Attachment A, Figure 2: Sampled Well Location Map (Oct. 2019), Attachment B: Sample Collection and Well Information Summary Table, Attachment C: Photographic Documentation Log, and Attachment D: Well Purge Sheets. 5.0 Sampling Methodology All field sampling activities were performed in accordance with the START V Site-Specific Health and Safety plan and Site-Specific Quality Assurance Project plan, and EPA’s Environmental Response Team (ERT)/Scientific, Engineering, Response and Analytical Services (SERAS) contractor’s Standard Operating Procedures (SOP) Numbers (Nos.) 2001: General Field Sampling Guidelines and 2007: Groundwater Sampling. All sampling activities were performed by START V under the direction of the EPA OSCs. The 35 groundwater monitoring wells and the one residential well (TILLET) were sampled via low-flow sampling methodology using submersible pumps (Grundfos Redi FLO 2 [Serial Nos. P113380101 and P114230033]) and dedicated Teflon tubing. Prior to sampling each well, a water level meter was utilized to collect and document the water level and well depth measurement, following which, a dedicated Teflon tubing attached to the sampling pump was lowered into the well with the pump intake set within the well screen interval. Each well was purged at steady flow rate until water quality indicator field parameters were stabilized. Water quality indicator parameters including pH, specific electric conductance (SEC), oxidation-reduction potential (ORP), turbidity, and dissolved oxygen (DO), were monitored using a water quality meter (Horiba U52 [Serial No. 3DM16249] and Horiba U500 [Serial No. FATHUG8A]) with flow through cell, and recorded in five-minute intervals during purging. After the water quality indicator field parameters had stabilized (+/- 10 percent [%]) following successful purging, groundwater samples were collected directly from the pump discharge tubing into three dedicated 40 milliliter (ml) volatile organic analysis (VOA) vials with Teflon-lined septum caps, preserved with HCl to pH below 2, and stored on ice immediately following collection to maintain a temperature of 4 Degrees Celsius (oC). Tutu Wellfield Site Final Monitoring and Residential Well Sampling Report January 2020 4 Prior to sampling each of the three residential well water supply systems, it was necessary to evacuate the standing water from the well, storage tank, and plumbing. This was accomplished by opening the cold water tap and purging the system for approximately 10 minutes and listening for the pump to turn on. This served as a good indicator that the wellhead, tank, and plumbing are being evacuated. If feasible, aerators, strainers and/or hose attachments present on the taps/faucet were removed prior to purging. Samples were then collected at a low, non-aerating flow rate into three dedicated 40 ml VOA vials with Teflon-lined septum caps, preserved with HCl to pH below 2, and stored on ice immediately following collection to maintain a temperature of 4 oC. All the water samples were collected for definitive data objective. Field duplicates and trip blanks were collected for quality assurance/quality control (QA/QC) purposes. All sample information were entered into the EPA SCRIBE database from which sample labels and Chains of Custody (COC) Record were generated. As part of this sampling event Remedial Action, START V was tasked with the deployment of PDB samplers in 10 monitoring wells at the Site. PDB samplers are made of low density polyethylene (LDPE), which acts as a semipermeable membrane. The PDB sampler is filled with deionized water and is in the shape of an 18 inch long cylindrical tube. VOCs, excluding certain ketones, ethers and alcohols, diffuse readily through the membrane. Equilibrium is established between the VOCs in the bag and those in the surrounding groundwater. Upon retrieval, the bags are opened to fill three 40 ml VOA vials preserved with HCl which are placed on ice and submitted to the laboratory for VOC analysis. Sampling of these PDBs is presently scheduled to occur in March 2020, when EPA and the ERRS contractor perform repairs of the two treatment systems. 6.0 Laboratory Receiving Samples The following laboratory was utilized for sample analysis during the sampling event.

Refer to Attachment B: Sample Collection and Well Information Summary Table and Attachment E: Chains of Custody Record. 8.0 Analytical Results Summary The validated analytical results of the water samples collected on September 30, 2019 through October 7, 2019 from 35 monitoring wells, one artesian well, and four residential wells were compared with the EPA MCLs for drinking water in accordance with the DWSHA dated March 2018. Based on validated analytical results of the water samples collected from the monitoring wells, at least one or more TCL VOCs, including tetrachloroethene, trichloroethene, vinyl chloride, methylene chloride, trans-1,2-dichloroethene, and cis-1,2-dichloroethene, exceeded their respective EPA MCL except for the water samples collected from three monitoring wells, MW- 13D, OU2-MW-1, and RD2, where TCL VOCs were not detected. Based on validated analytical results of the water samples collected from the monitoring wells, concentrations of tetrachloroethene equaled or exceeded the EPA MCL in water samples collected from 13 monitoring wells, including DW-2, MW-12D, MW-7, RD-7, IW-1S, MW-15, MW-1D, OU2-MD-2, OU2-MW-2, OU2-MW-3, OU2-MW-4, OU2-MW-5, and RD-5; concentrations of trichloroethene exceeded the EPA MCL in water samples collected from six monitoring wells, including MW-1D, OU2-MD-2, OU2-MW-2, OU2-MW-3, OU2-MW-4, and OU2-MW-5; concentrations of vinyl chloride exceeded the EPA MCL in water samples collected from seven monitoring wells, including IW-1, IW-2, MW-21D, OU2-MD-2, OU2-MW-2, RD-13, and RD-9; the concentration of trans-1,2-dichloroethene exceeded the EPA MCL in water sample collected from IW-1; and the concentration of cis-1,2-dichloroethene exceeded the EPA MCL in water sample collected from OU2-MD-2. Based on validated analytical results, concentrations of at least one or more TCL VOCs, including chloromethane, acetone, carbon disulfide, vinyl chloride, methylene chloride, cis-1,2- dichloroethene, 2-butanone, chloroform, benzene, trichloroethene, toluene, o-xylene, m,p-xylene, styrene, dibromochloromethane, and bromoform, were detected in the rinsate blanks. Although the concentrations of all the detected compounds were well below their respective EPA MCLs, except for tetrachloroethene which exceeded the EPA RML in one rinsate blank (RB-1-191004- 01), the presence of these low level contaminants in the rinsate blanks suggests that the deionized water utilized in preparing the rinsate blanks may have been contaminated, and/or the pump decontamination process may not be adequate in preventing potential cross contamination during sampling. Based on validated analytical results, concentrations of at least one or more TCL VOCs, including chloromethane, acetone, chloroform, benzene, toluene, o-xylene, m,p-xylene, and styrene, were detected in the trip blanks. Although the low concentrations of these detected compounds were well below their respective EPA MCLs, their presence in the trip blank suggests that the deionized water utilized in preparing the trip blank may have been contaminated. Tutu Wellfield Site Final Monitoring and Residential Well Sampling Report January 2020 6 Based on validated analytical results of the water samples collected from the residential wells, low level concentrations of at least one or more TCL VOCs, including dichlorodifluoromethane, trans- 1,2-dichloroethene, methyl tert-butyl ether, cis-1,2-dichloroethene, chloroform, trichloroethene, and tetrachloroethene, were detected at concentrations well below their respective EPA MCLs in all five water samples, including the one field duplicate, except for tetrachloroethene concentration in sample P0004-TILLET-101005-01 which exceeded the EPA MCL. Based on validated analytical results, low level concentrations of chloromethane, acetone, toluene, ethylbenzene, o-, m-, and p-xylenes, and styrene, were detected in the trip blank. Although the low concentrations of these detected compounds were well below their respective EPA MCLs, their presence in the trip blank suggests that the deionized water utilized in preparing the trip blank may have been contaminated. Refer to Attachment A, Figure 2: Sampled Well Location Map (Oct. 2019), Attachment B, Table 2: Validated Monitoring Well Water Analytical Results Summary Table - TCL VOCs Table 3: Validated Residential Well Water Analytical Results Summary Table - TCL VOCs, and Attachment F: Data Validation Report. 9.0 Conclusion On October 7, 2019, EPA and START V completed a monitoring and residential well sampling event. A total of 39 water samples, including three field duplicates, were collected from 35 monitoring wells and one artesian well, and five water samples, including one field duplicate, were collected from four residential wells (SMITH, STEELE, DELEGARD, and TILLET). All the monitoring wells and TILLET well were sampled using low flow sampling method, water samples were collected directly from taps and faucets associated with the remaining three residential wells, and water sample was collected directly from the free flowing water of artesian well RD-6. All the water samples were analyzed by the assigned laboratory for TCL VOCs. Analytical results were compared with the EPA MCLs contained in the DWSHA dated March 2018. Based on analytical results of water samples collected from the monitoring wells, at least one or more TCL VOCs, including tetrachloroethene, trichloroethene, vinyl chloride, methylene chloride, trans-1,2-dichloroethene, and cis-1,2-dichloroethene, exceeded their respective EPA MCL except for the water samples collected from three monitoring wells, MW-13D, OU2-MW-1, and RD2, where TCL VOCs were not detected. In addition, concentrations of tetrachloroethene equaled or exceeded the EPA MCL in water samples collected from 13 of the 35 monitoring wells sampled, including DW-2, MW-12D, MW-7, RD-7, IW-1S, MW-15, MW-1D, OU2-MD-2, OU2-MW-2, OU2-MW-3, OU2-MW-4, OU2-MW-5, and RD-5. Based on analytical results of water samples collected from the residential wells, concentrations of TCL VOCs were well below their respective EPA MCLs in all five water samples, including the one field duplicate, except for tetrachloroethene concentration in water sample collected from TILLET well which exceeded the EPA MCL.

These wells will continue to be monitored to verify contaminant trends. 3. Samples were not collected from the Eglin-3 well in April 2013 because the supply well pump was broken. 4. The Steele well has not been sampled since April 2015 due to an inoperable well pump. 5. The Steele and Eglin-3 wells have been removed from the list of wells to be sampled annually until well pumps are repaired. 6. Samples were not collected at Delegard or Laplace during the 2018 sampling event. There was no power available and both well pumps were damaged in hurricanes Irma and Maria. 7. Total CVOCs do not include values <1.0 with a J qualifier. 8. NA - Not Applicable - Well has been destroyed. 9. Hurricane Maria made landfall on Puerto Rico September 20, 2017.

Due to various quality control (QC) problems some analytes may have been qualified with a II J" ( estimated), 11N" (presumptive evidence for the presence of the material), 11U" (non-detect), or II JN" (presumptive evidence for the presence of the material at an estimated value) flag. All action is detailed on the attached sheets. The "R11 flag means that the associated value is unusable.

HOLDING TIME: The amount of an analyte in a sample can change with time due to chemical instability, degradation, volatilization, etc. If the specified holding time is exceeded, the data may not be valid. Those analytes detected in the samples whose holding time has been exceeded will be qualified as estimated, "J". The non-detects (sample quantitation limits) will be flagged ATTACHMENT 1 Page 3 of6 as estimated, "J", or unusable, "R" if the holding times are grossly exceeded. Qualifications were applied to the samples and analytes as shown below. No problems were found for this criterion. 2. DEUTERATED MONITORING COMPOUNDS (DMCs) All samples are spiked with DMC compounds prior to sample preparation to evaluate overall laboratory performance and efficiency of the analytical technique. If the measured DMC recoveries were outside contract specifications, qualifications were applied to the samples and analytes as shown below. The following samples have one or more DMC/surrogate recovery values less than the primary lower limit but greater than or equal to the expanded lower limit of the criteria window. Detected compounds are qualified J-. Non-detected compounds are qualified UJ. 1,1-Dichloroethene-d2: RB-1-190930-01, RB-1-191001-01, and RB-2-191001-01 trans-1,2-Dichloroethene, cis-1,2-Dichloroethene, 1, 1-Dichloroethene 3. MATRIX SPIKE/ MATRIX SPIKE DUPLICATE (MS/MSD) RECOVERY: MS/MSD data is generated to determine the long-term precision and accuracy of the analytical method in various matrices. The MS/MSD data may be used in conjunction with other QC criteria for additional qualification of data. Sample MW-12D-001-01 was used for MS/MSD analyses. No problems were found for this criterion. 4. BLANK CONTAMINATION: Quality assurance (QA) blanks, i.e., method, trip, field, or rinse blanks are prepared to identify any contamination which may have been introduced into the samples during sample preparation or field activity. Method blanks measure laboratory contamination. Trip blanks measure cross-contamination of samples during shipment. Field and rinse blanks measure cross-contamination of samples during field operations. Depending on the amount of contamination present in the QA blanks, the analytes are qualified as non- detects, "U". Qualifications were applied to the samples and analytes as shown below. A) Method blank contamination: No problems were found for this criterion. B) Trip or Rinse blank contamination: Chloromethane concentration in trip blank was less than the contract required quantitation limit (CRQL). The chloromethane concentrations in samples MW-12D-001-01, MW-2-001-01, and MW-25-001-01 were also reported less than the the CRQLs. Detected compounds are qualified U. Non-detected compounds are not qualified. Sample concentrations reported below CRQL have been elevated to the CRQL. ATTACHMENT 1 Page 4 of6 Chloromethane - CRQL with 'U' qualifier applied to samples MW-12D-001-0l, MW-2-001- 01, and MW-25-001-01 Acetone was detected at concentration above 4 times ( 4x) CRQL in the trip blank and rinsate blanks. Detected acetone results were qualified as non-detect (U) at the blank concentration. Non-detected compounds were not qualified. Acetone-Blank value with 'U' qualifier applied to samples DW-2-001-01, MW-1 lD-001-01, MW-12D-001-01, MW-12D-001-02, MW-2-001-01, MW-25-001-01, MW-7-001-01, MW-8- 001-01, RD-7-001-01, and RD-8-001-01 Benzene, toluene, o-xylene, m,p-xylene, styrene, and/or carbon disulfide were detected less than CRQL in the trip blank and/or rinsate blanks. Since, benzene, toluene, o-xylene, m,p-xylene, styrene, and/or carbon disulfide samples results were non-detect in associated samples, no qualification was required. D) Storage Blank associated with VOA samples only: No problems were found for this criterion. E) Tentatively Identified Compounds: No problems were found for this criterion. 5. MASS SPECTROMETER TUNING: Tuning and performance criteria are established to ensure adequate mass resolution, proper identification of compounds and to some degree, sufficient instrument sensitivity. These criteria are not sample specific. Instrument performance is determined using standard materials. Therefore, these criteria should be met in all circumstances. The tuning standard for volatile organics is Bromofluorobenzene (BFB). If the mass calibration is in error, all associated data will be classified as unusable "R". Qualifications were applied to the samples and analytes as shown below. No problems were found for this criterion. 6. CALIBRATION: Satisfactory instrument calibration is established to ensure that the instrument is capable of producing acceptable quantitative data. An initial calibration demonstrates that the instrument is capable of giving acceptable performance at the beginning of an experimental sequence. The continuing calibration verifications (CCVs) document that the instrument is giving satisfactory daily performance. A) Response Factor GC/MS: The response factor measures the instrument's response to specific chemical compounds. The response factor for the target compound must be ~ 0.05, and ~ 0.01 for the poor performers in both the initial and opening continuing calibrations. For closing continuing ATTACHMENT 1 Page 5 of6 calibration response factor for all target compounds must be 2:: 0.01. A value < 0.05 for target compounds or < 0.01 for the poor performers indicates a serious detection and quantitation problem (poor sensitivity). Analytes detected in the sample will be qualified as estimated, "J". All non-detects for that compound will be rejected "R". No problems were found for this criterion. B) Percent Relative Standard Deviation (%RSD) and Percent Difference (%D): Percent RSD is calculated from the initial calibration and is used to indicate the stability of the specific compound response factor over increasing concentration. Percent D compares the response factor of the CCV to the mean relative response factor (RRF) from the initial calibration. Percent D is a measure of the instrument's daily performance. Percent RSD and %D must meet criteria listed in Table 2 of SOP HW-34A. A value outside of these limits indicates potential detection and quantitation errors. For these reasons, all positive results are flagged as estimated, "J". Non-detects are flagged "UJ" for %D values outside criteria only. If %RSD exceeds QC criteria, non-detects may be qualified using professional judgement. Qualifications were applied to the samples and analytes as shown below. No problems were found for this criterion. 7. INTERNAL STANDARDS PERFORMANCE GC/MS: Internal standards (IS) performance criteria ensure that the GC/MS sensitivity and response are stable during every experimental run. The internal standard area count must be in the range of 60% - 140 % of the associated continuing calibration internal standard from the associated continuing calibration standard. If the area count is greater than 140%, all positive results quantitated using that IS are qualified as estimated "J-", and non-detects are not qualified. If the area count is less than 60% of the associated standard, all positive results for compounds quantitated with that IS are qualified as estimated "J+" and all non-detects are qualified "R". If an internal standard retention time varies by more than 20 seconds, the reviewer will use professional judgment to determine either partial or total rejection of the data for that sample fraction. Qualifications were applied to the samples and analytes as shown below. No problems were found for this criterion. 8. FIELD DUPLICATES: Sample pairs MW-12D-001-01 and MW-12D-001-02 were collected and analyzed as an overall indication of precision. This analysis measures both field and laboratory precision. A control limit of 20% for the Relative Percent Difference (RPO) will be used for original and duplicate sample values 2:: five times (Sx) the Contract Required Quantitation Limit (CRQL). A control limit of the CRQL will be used if either the sample or duplicate value is < Sx the CRQL. For field duplicate analysis that does not meet the technical criteria, the action was applied to only the field sample and it's duplicate. ATTACHMENT 1 Page 6 of6 Chloromethane was detected in sample MW-12D-001-01 at a concentration less than the reporting limit but was not detected in its field duplicate MW-12D-001-02. Chloromethane was previously qualified as U in field sample MW-12D-001-01, due to trip/rinsate blanks contamination. Since both results are non-detected, no further qualification was required. Acetone was detected in sample MW-12D-001-01 and its field duplicate MW-12D-001-02 at a concentration less than the reporting limit. Acetone was previously qualified as U in field sample MW-12D-001-01 and its field duplicate MW-12D-001-02, due to trip/rinsate blanks contamination. Since both results are non-detected, no further qualification was required. 9. COMPOUND IDENTIFICATION: Target compounds are identified on the GC/MS by using the analyte's relative retention time (RRT) and by comparison to the ion spectra obtained from known standards. For the results to be a positive hit, the sample peak must be within a window of 0.06 RRT units of the standard compound and have an ion spectrum which has a ratio of the primary and secondary m/z intensities within 20% of that in the standard compound. For the tentatively identified compounds (TIC) the ion spectra must match accurately. In the cases where there is not an adequate ion spectrum match, the laboratory may have provided false positive identifications. Qualifications were applied to the samples and analytes as shown below. No problems were identified. 10. CONTRACT NON-COMPLIANCE: No problems were identified. 11. FIELD DOCUMENTATION: The Chain-of-Custody was reviewed; no problems were found. 12. OTHER PROBLEMS: None 13. DILUTIONS, RE-EXTRACTIONS & REANALYSIS: Samples may be reanalyzed after dilution, re-extraction and for other QC reasons. In such cases, the best result values are consolidated in one single report and the other report is marked as not to be used.

HOLDING TIME: The amount of an analyte in a sample can change with time due to chemical instability, degradation, volatilization, etc. If the specified holding time is exceeded, the data may not be valid. Those analytes detected in the samples whose holding time has been exceeded will be qualified as estimated, "J". The non-detects (sample quantitation limits) will be flagged as estimated, "J", or unusable, "R" if the holding times are grossly exceeded. Qualifications were applied to the samples and analytes as shown below. No problems were found for this criterion. 2. DEUTERATED MONITORING COMPOUNDS (DMCs) All samples are spiked with DMC compounds prior to sample preparation to evaluate overall laboratory performance and efficiency of the analytical technique. If the measured DMC recoveries were outside contract specifications, qualifications were applied to the samples and analytes as shown below. No problems were found for this criterion. 3. MATRIX SPIKE/ MATRIX SPIKE DUPLICATE (MS/MSD) RECOVERY: MS/MSD data is generated to determine the long-term precision and accuracy of the analytical method in various matrices. The MS/MSD data may be used in conjunction with other QC criteria for additional qualification of data. Not Applicable 4. BLANK CONTAMINATION: Quality assurance (QA) blanks, i.e., method, trip, field, or rinse blanks are prepared to identify any contamination which may have been introduced into the samples during sample preparation or field activity. Method blanks measure laboratory contamination. Trip blanks measure cross-contamination of samples during shipment. Field and rinse blanks measure cross-contamination of samples during field operations. Depending on the amount of contamination present in the QA blanks, the analytes are qualified as non- detects, "U". Qualifications were applied to the samples and analytes as shown below. A) Method blank contamination: No problems were found for this criterion. B) Trip blanks contamination: Chloromethane, chloroform, toluene, m,p-xylene, and styrene concentrations were less than ( <) the contract required quantitation limit (CRQL); and acetone concentration was< 2 times (2x) ATTACHMENT 1 Page 4 of7 CRQL in trip blanks TB-191007-01 and TB-2-191007-01. Detected compounds are qualified U. Non-detected compounds are not qualified. Sample concentrations reported below CRQL have been elevated to the CRQL and sample concentration greater than(>) 2 x CRQL and< 4x CRQL have been reported as concentration of sample with a U. Chloromethane - CRQL value with 'U' qualifier applied to samples OU2-MW-6-001-01, RD- 1-001-01, RD-6-001-01, and RD-9-001-01 Toluene - CRQL value with 'U' qualifier applied to samples OU2-MW-6-001-01, RD-1-001-01, RD-14-001-01, RD-3-001-01, RD-4-001-01, and RD-9-001-01 Acetone - CRQL value with 'U' qualifier applied to samples RD-1-001-01, RD-2-001-01, RD-3- 001-01, RD-4-001-01, RD-5-001-01, RD-6-001-01, and RD-9-001-01 Acetone- sample concentration with 'U' qualifier applied to sample OU2-MW-6-001-01 C) Rinsate blanks contamination: Acetone, carbon disulfide, toluene, m,p-xylene, styrene, methylene chloride, 2-butanone, dibromochloromethane, and bromoform were detected at concentration less than CRQL in the rinsate blanks. Since, acetone and toluene were previously qualified due to trip blanks contamination, no further action was required. Carbon disulfide, m,p-xylene, styrene, 2- butanone, dibromochloromethane, and bromoform were not detected in samples associated with rinsate blanks, therefore, no further action was required. Since, benzene, toluene, o-xylene, m,p- xylene, styrene, and/or carbon disulfide samples results were non-detect in associated samples, no qualification was required. Sample concentrations reported below CRQL have been elevated to the CRQL. Methylene Chloride - CRQL value with 'U' qualifier applied to sample RD-13-001-01 D) Storage Blank associated with VOA samples only: No problems were found for this criterion. E) Tentatively Identified Compounds: No problems were found for this criterion. 5. MASS SPECTROMETER TUNING: Tuning and performance criteria are established to ensure adequate mass resolution, proper identification of compounds and to some degree, sufficient instrument sensitivity. These criteria are not sample specific. Instrument performance is determined using standard materials. Therefore, these criteria should be met in all circumstances. The tuning standard for volatile organics is Bromofluorobenzene (BFB). If the mass calibration is in error, all associated data will be classified as unusable "R". Qualifications were applied to the samples and analytes as shown below. No problems were found for this criterion. ATTACHMENT 1 Page 5 of7 6. CALIBRATION: Satisfactory instrument calibration is established to ensure that the instrument is capable of producing acceptable quantitative data. An initial calibration demonstrates that the instrument is capable of giving acceptable performance at the beginning of an experimental sequence. The continuing calibration verifications (CCVs) document that the instrument is giving satisfactory daily performance. A) Response Factor GC/MS: The response factor measures the instrument's response to specific chemical compounds. The response factor for the target compound must be ~ 0.05, and ~ 0.01 for the poor performers in both the initial and opening continuing calibrations. For closing continuing calibration response factor for all target compounds must be ~ 0.01. A value < 0.05 for target compounds or < 0.01 for the poor performers indicates a serious detection and quantitation problem (poor sensitivity). Analytes detected in the sample will be qualified as estimated, "J". All non-detects for that compound will be rejected "R". No problems were found for this criterion. B) Percent Relative Standard Deviation (%RSD) and Percent Difference (%D): Percent RSD is calculated from the initial calibration and is used to indicate the stability of the specific compound response factor over increasing concentration. Percent D compares the response factor of the CCV to the mean relative response factor (RRF) from the initial calibration. Percent D is a measure of the instrument's daily performance. Percent RSD and %D must meet criteria listed in Table 2 of SOP HW-34A. A value outside of these limits indicates potential detection and quantitation errors. For these reasons, all positive results are flagged as estimated, "J". Non-detects are flagged "UJ" for %D values outside criteria only. If %RSD exceeds QC criteria, non-detects may be qualified using professional judgement. Qualifications were applied to the samples and analytes as shown below. No problems were found for this criterion. 7. INTERNAL STANDARDS PERFORMANCE GC/MS: Internal standards (IS) performance criteria ensure that the GC/MS sensitivity and response are stable during every experimental run. The internal standard area count must be in the range of 60% - 140 % of the associated continuing calibration internal standard from the associated continuing calibration standard. If the area count is greater than 140%, all positive results quantitated using that IS are qualified as estimated "J-", and non-detects are not qualified. If the area count is less than 60% of the associated standard, all positive results for compounds quantitated with that IS are qualified as estimated "J+" and all non-detects are qualified "R". If an internal standard retention time varies by more than 20 seconds, the reviewer will use professional judgment to determine either partial or total rejection of the data for that sample fraction. Qualifications were applied to the samples and analytes as shown below. No problems were found for this criterion. ATTACHMENT 1 Page 6 of7 8. FIELD DUPLICATES: This analysis measures both field and laboratory precision. A control limit of 20% for the Relative Percent Difference (RPO) will be used for original and duplicate sample values ~ five times (5x) the Contract Required Quantitation Limit (CRQL). A control limit of the CRQL will be used if either the sample or duplicate value is < 5x the CRQL. For field duplicate analysis that does not meet the technical criteria, the action was applied to only the field sample and it's duplicate. Not applicable 9. COMPOUND IDENTIFICATION: Target compounds are identified on the GC/MS by using the analyte's relative retention time (RRT) and by comparison to the ion spectra obtained from known standards. For the results to be a positive hit, the sample peak must be within a window of 0.06 RRT units of the standard compound and have an ion spectrum which has a ratio of the primary and secondary m/z intensities within 20% of that in the standard compound. For the tentatively identified compounds (flC) the ion spectra must match accurately. In the cases where there is not an adequate ion spectrum match, the laboratory may have provided false positive identifications .. Qualifications were applied to the samples and analytes as shown below. For all TICs where there was a presumptive evidence of a match as compared to the reference spectra (>85% match), results were qualified as tentatively identified (NJ) with approximated concentrations. TICs identified and reported by the laboratory with a poor match compared to the reference spectra (<85% match) were changed to "Unknown" by the validator and results were qualified as estimated (J) (refer to qualified Form Is). 10. CONTRACT NON-COMPLIANCE: No problems were identified. 11. FIELD DOCUMENTATION: The Chain-of-Custody was reviewed; no problems were found. 12. OTHER PROBLEMS: Tetrachloroethene concentration exceeded the calibration range in sample RD-5-001-01. Concentration of the tetrachloroethene was reported from the dilution analysis (RD-5-001- 0lDL). Vinyl chloride concentration exceeded the calibration range in sample RD-9-001-01. The concentration of vinyl chloride was reported from the dilution analysis (RD-9-001-0IDL). Sample RD-13-001-01 was diluted I Ox due to bad matrix. ATTACHMENT 1 Page 7 of7 13. DILUTIONS, RE-EXTRACTIONS & REANALYSIS: Samples may be reanalyzed after dilution, re-extraction and for other QC reasons. In such cases, the best result values are consolidated in one single report and the other report is marked as not to be used.

HOLDING TIME: The amount of an analyte in a sample can change with time due to chemical instability, degradation, volatilization, etc. If the specified holding time is exceeded, the data may not be valid. Those analytes detected in the samples whose holding time has been exceeded will be qualified as estimated, "J". The non-detects (sample quantitation limits) will be flagged as estimated, "J", or unusable, "R" if the holding times are grossly exceeded. Qualifications were applied to the samples and analytes as shown below. No problems were found for this criterion. 2. DEUTERATED MONITORING COMPOUNDS (DMCs) All samples are spiked with DMC compounds prior to sample preparation to evaluate overall laboratory performance and efficiency of the analytical technique. If the measured DMC recoveries were outside contract specifications, qualifications were applied to the samples and analytes as shown below. The following samples have one or more DMC/surrogate recovery values less than the primary lower limit but greater than or equal to the expanded lower limit of the criteria window. Detected compounds are qualified J-. Non-detected compounds are qualified UJ. 1,1-Dichloroethene-d2: IW-1-001-01 trans-1,2-Dichloroethene, cis-1,2-Dichloroethene, 1, 1-Dichloroethene The following samples have one or more DMC/surrogate recovery values greater than or equal to the expanded lower limit of the criteria window. Detected compounds are qualified J-. Non- detected compounds are not qualified. Vinyl Chloride-d3: OU2-MD-2-001-01 Vinyl Chloride 3. MATRIX SPIKE/ MATRIX SPIKE DUPLICATE (MS/MSD) RECOVERY: MS/MSD data is generated to determine the long-term precision and accuracy of the analytical method in various matrices. The MS/MSD data may be used in conjunction with other QC criteria for additional qualification of data. Sample IW-2-001-01 was used for MS/MSD analyses. No problems were found for this criterion. The MS/MSD analyses of sample MW-6D-001-01 yielded low MS recoveries for benzene and toluene; using professional judgment, the non-detected results for benzene and toluene in sample MW-6D-001-01 was estimated (UJ). ATTACHMENT 1 Page 4of8 4. BLANK CONTAMINATION: Quality assurance (QA) blanks, i.e., method, trip, field, or rinse blanks are prepared to identify any contamination which may have been introduced into the samples during sample preparation or field activity. Method blanks measure laboratory contamination. Trip blanks measure cross-contamination of samples during shipment. Field and rinse blanks measure cross-contamination of samples during field operations. Depending on the amount of contamination present in the QA blanks, the analytes are qualified as non- detects, "U". Qualifications were applied to the samples and analytes as shown below. A) Method blank contamination: No problems were found for this criterion. B) Trip blank contamination: Chloromethane, chloroform, toluene, m,p-xylene, and styrene concentrations were less than ( <) the contract required quantitation limit (CRQL); and acetone concentration was< 2 x CRQL in trip blanks TB-191007-01 and TB-2-191007-01. Detected compounds are qualified U. Non- detected compounds are not qualified. Sample concentrations reported below CRQL have been elevated to the CRQL and sample concentration CRQL and< 2 times (2x) CRQL have been reported as concentration of sample with a U. Chloromethane - CRQL value with 'U' qualifier applied to samples IW-2-001-01, IW-2-001- 02, MW-14-001-01, and OU2-MW-2-001-01 Acetone - CRQL value with 'U' qualifier applied to samples IW-lS-001-01, MW-13D-001-01, MW-14-001-01, MW-15-001-01, MW-lD-001-01, MW-21D-001-01, MW-6D-001-01, OU2- MD-2-001-01, OU2-MW-1-001-01, OU2-MW-2-001-01, and OU2-MW-5-001-01 Toluene - CRQL value with 'U' qualifier applied to samples IW-2-001-01, IW-2-001-02, MW- 13D-001-01, MW-15-001-01, and MW-5-001-01 Chloroform concentration in trip blanks TB-191007-01 and TB-2-191007-01 were less than the CRQL. The chloroform concentrations in samples listed below were greater than CRQL but less than 2 x CRQL. Detected compounds are qualified U. Non-detected compounds are not qualified. Concentrations in samples listed below will be reported with 'U' at sample concentrations. Chloroform - 'U' qualifier applied to samples MW-14-001-01, MW-15-001-01, MW-6D-001- 01, OU2-MW-1-001-01, and OU2-MW-2-001-01 C) Rinse blanks contamination: (8-rinsate blanks can be found in SDG K5309) Benzene, acetone, toluene, vinyl chloride, m,p-xylene, styrene, methylene chloride, trichloroethene, cis-1,2-dichloroethene, 2-butanone, dibromochloromethane, and/or carbon disulfide were detected less than CRQL in the rinsate blanks. Since, acetone and toluene were ATTACHMENT 1 Page 5 of8 previously qualified due to trip blank concentration, therefore, no further qualifications were required. Benzene, vinyl chloride, m,p-xylene, styrene, methylene chloride, trichloroethene, cis- 1,2-dichloroethene, 2-butanone, dibromochloromethane, and/or carbon disulfide samples results were non-detect in associated samples, no qualification was required. Trichloroethene concentration in rinsate blank RB-2-191003-01 was <CRQL. Detected compounds are qualified 'U'. Non-detected compounds are not qualified. Sample concentrations reported below CRQL have been elevated to the CRQL and qualified with 'U' and sample concentration greater than(>) CRQL but< 2x CRQL were reported at sample concentration with 'U'. Trichloroethene - CRQL value with 'U' qualifier applied to samples MW-10D-001-01 and MW-6D-001-02 Trichloroethene - 'U' qualifier applied to samples MW-13D-001-01 Tetrachloroethene was reported greater than CRQL in rinsate blank RB-2-191003-01. The following samples have analyte concentrations reported above the CRQL and less than blank concentrations were raised to the level of the blank concentration with a U. Sample concentrations reported below CRQL have been elevated to the CRQL and qualified with a U Non-detected compounds are not qualified. Tetrachloroethene - Blank value with 'U' qualifier applied to samples MW-13D-001-01, MW- 6D-001-01, and MW-6D-001-02 Tetrachloroethene - CRQL value with 'U' qualifier applied to sample OU2-MW-1-001-01 D) Storage Blank associated with VOA samples only: No problems were found for this criterion. E) Tentatively Identified Compounds: No problems were found for this criterion. 5. MASS SPECTROMETER TUNING: Tuning and performance criteria are established to ensure adequate mass resolution, proper identification of compounds and to some degree, sufficient instrument sensitivity. These criteria are not sample specific. Instrument performance is determined using standard materials. Therefore, these criteria should be met in all circumstances. The tuning standard for volatile organics is Bromofluorobenzene (BFB). If the mass calibration is in error, all associated data will be classified as unusable "R". Qualifications were applied to the samples and analytes as shown below. No problems were found for this criterion. ATTACHMENT 1 Page 6 of8 6. CALIBRATION: Satisfactory instrument calibration is established to ensure that the instrument is capable of producing acceptable quantitative data. An initial calibration demonstrates that the instrument is capable of giving acceptable performance at the beginning of an experimental sequence. The continuing calibration verifications (CCVs) document that the instrument is giving satisfactory daily performance. A) Response Factor GC/MS: The response factor measures the instrument's response to specific chemical compounds. The response factor for the target compound must be ~ 0.05, and ~ 0.01 for the poor performers in both the initial and opening continuing calibrations. For closing continuing calibration response factor for all target compounds must be ~ 0.01. A value < 0.05 for target compounds or < 0.01 for the poor performers indicates a serious detection and quantitation problem (poor sensitivity). Analytes detected in the sample will be qualified as estimated, "J". All non-detects for that compound will be rejected "R". No problems were found for this criterion. B) Percent Relative Standard Deviation (%RSD) and Percent Difference (%D): Percent RSD is calculated from the initial calibration and is used to indicate the stability of the specific compound response factor over increasing concentration. Percent D compares the response factor of the CCV to the mean relative response factor (RRF) from the initial calibration. Percent D is a measure of the instrument's daily performance. Percent RSD and %D must meet criteria listed in Table 2 of SOP HW-34A. A value outside of these limits indicates potential detection and quantitation errors. For these reasons, all positive results are flagged as estimated, "J". Non-detects are flagged "UJ" for %D values outside criteria only. If %RSD exceeds QC criteria, non-detects may be qualified using professional judgement. Qualifications were applied to the samples and analytes as shown below. No problems were found for this criterion. 7. INTERNAL STANDARDS PERFORMANCE GC/MS: Internal standards (IS) performance criteria ensure that the GC/MS sensitivity and response are stable during every experimental run. The internal standard area count must be in the range of 60% - 140 % of the associated continuing calibration internal standard from the associated continuing calibration standard. If the area count is greater than 140%, all positive results quantitated using that IS are qualified as estimated "J-", and non-detects are not qualified. If the area count is less than 60% of the associated standard, all positive results for compounds quantitated with that IS are qualified as estimated "J+" and all non-detects are qualified "R". If an internal standard retention time varies by more than 20 seconds, the reviewer will use professional judgment to determine either partial or total rejection of the data for that sample fraction. Qualifications were applied to the samples and analytes as shown below. No problems were found for this criterion. ATTACHMENT 1 Page 7 of8 8. FIELD DUPLICATES: This analysis measures both field and laboratory precision. A control limit of 20% for the Relative Percent Difference (RPD) will be used for original and duplicate sample values ~ five times (5x) the Contract Required Quantitation Limit (CRQL). A control limit of the CRQL will be used if either the sample or duplicate value is < 5x the CRQL. For field duplicate analysis that does not meet the technical criteria, the action was applied to only the field sample and it's duplicate. For field duplicate pair IW-2-001-01 and IW-2-001-02, the RPDs were >50% for carbon disulfide (74.4%) and 1,3-dichlorobenzene (128%). The positive results and/or non-detects in sample IW-2-001-01 and its field duplicate IW-2-001-02 were estimated (J/UJ) for carbon disulfide and 1,3-dichlorobenzene. For field duplicate pair MW-6D-001-01 and MW-6D-001-02, the RPDs were >50% for acetone. Acetone was detected in sample MW-6D-001-01 at a concentration less than the reporting limit but was not detected in its field duplicate MW-6D-001-02. Since, acetone was previously qualified as U in field sample MW-6D-001-0l, due to trip/rinsate blanks contamination, both results are non-detected, no further qualification was required. 9. COMPOUND IDENTIFICATION: Target compounds are identified on the GC/MS by using the analyte's relative retention time (RRT) and by comparison to the ion spectra obtained from known standards. For the results to be a positive hit, the sample peak must be within a window of 0.06 RRT units of the standard compound and have an ion spectrum which has a ratio of the primary and secondary m/z intensities within 20% of that in the standard compound. For the tentatively identified compounds (TIC) the ion spectra must match accurately. In the cases where there is not an adequate ion spectrum match, the laboratory may have provided false positive identifications. Qualifications were applied to the samples and analytes as shown below. For all TICs where there was a presumptive evidence of a match as compared to the reference spectra (>85% match), results were qualified as tentatively identified (NJ) with approximated concentrations. TICs identified and reported by the laboratory with a poor match compared to the reference spectra ( <85% match) were changed to "Unknown" by the validator and results were qualified as estimated (J) (refer to qualified Form Is). 10. CONTRACT NON-COMPLIANCE: No problems were identified. 11. FIELD DOCUMENTATION: The Chain-of-Custody was reviewed; no problems were found. ATTACHMENT 1 Page 8 of8 12. OTHER PROBLEMS: Vinyl chloride concentration exceeded the calibration range in sample IW-1-001-01. The concentration of vinyl chloride was reported from the dilution analysis (IW-1-001-0lDL). Tetrachloroethene concentration exceeded the calibration range in sample MW-15-001-01. The concentration oftetrachloroethene was reported from the dilution analysis (MW-15-001-0lDL). Cis-1,2-Dichloroethene and tetrachloroethene concentrations exceeded the calibration range in sample MW-1D-001-01. The concentrations of cis-1,2-dichloroethene and tetrachloroethene were reported from the dilution analysis (MW-1D-001-0lDL). Vinyl chloride, cis-1,2-dichloroethene, trichloroethene, and tetrachloroethene concentrations exceeded the calibration range in sample OU2-MD-2-001-0l. The concentrations of vinyl chloride, cis-1,2-dichloroethene, trichloroethene, and tetrachloroethene were reported from the dilution analysis (OU2-MD-2-001-01DL). Cis-1,2-Dichloroethene and tetrachloroethene concentrations exceeded the calibration range in sample OU2-MW-2-001-01. Concentrations of the cis-1,2-dichloroethene and tetrachloroethene were reported from the dilution analysis (OU2-MW-2-001-01DL). Cis-1,2-Dichloroethene, trichloroethene, and tetrachloroethene concentrations exceeded the calibration range in sample OU2-MW-5-001-0l. The concentrations of cis-1,2-dichloroethene, trichloroethene, and tetrachloroethene were reported from the dilution analysis (OU2-MW-5- 001-01DL). Samples IW-1-001-01 (x200), OU2-MW-3-001-01 (x40), and OU2-MW04001-01 (x50) were diluted due to bad matrix. 13.

HOLDING TIME: The amount of an analyte in a sample can change with time due to chemical instability, degradation, volatilization, etc. If the specified holding time is exceeded, the data may not be valid. Those analytes detected in the samples whose holding time has been exceeded will be qualified as estimated, "J". The non-detects (sample quantitation limits) will be flagged as estimated, "J", or unusable, "R" if the holding times are grossly exceeded. Qualifications were applied to the samples and analytes as shown below. No problems were found for this criterion. 2. DEUTERATED MONITORING COMPOUNDS (DMCs) All samples are spiked with DMC compounds prior to sample preparation to evaluate overall laboratory performance and efficiency of the analytical technique. If the measured DMC recoveries were outside contract specifications, qualifications were applied to the samples and analytes as shown below. No problems were found for this criterion. ATTACHMENT 1 Page 3 of6 3. MATRIX SPIKE/ MATRIX SPIKE DUPLICATE (MS/MSD) RECOVERY: MS/MSD data is generated to determine the long-term precision and accuracy of the analytical method in various matrices. The MS/MSD data may be used in conjunction with other QC criteria for additional qualification of data. Sample P0002-STEELE-191007-01 was used for MS/MSD analyses. No problems were found for this criterion. 4. BLANK CONTAMINATION: Quality assurance (QA) blanks, i.e., method, trip, field, or rinse blanks are prepared to identify any contamination which may have been introduced into the samples during sample preparation or field activity. Method blanks measure laboratory contamination. Trip blanks measure cross-contamination of samples during shipment. Field and rinse blanks measure cross-contamination of samples during field operations. Depending on the amount of contamination present in the QA blanks, the analytes are qualified as non- detects, "U". Qualifications were applied to the samples and analytes as shown below. A) Method blank contamination: No problems were found for this criterion. B) Trip or Rinse blank contamination: Chloromethane concentration in trip blank was less than the contract required quantitation limit (CRQL). The chloromethane concentrations in the samples listed below were also reported less than the CRQLs. Detected compounds are qualified U. Non-detected compounds are not qualified. Sample concentrations reported below CRQL have been elevated to the CRQL. Chloromethane - 'U' qualifier applied to samples P000l-SMITH-1101007-01, P0002- STEELE-191007-01, P0002-STEELE-191007-02, and P0003-DELEGARD-191007-01 Acetone concentration in trip blank was less than 2 times (2x) CRQL. The acetone concentrations in the samples listed below were also reported less than the 2x CRQLs. Detected compounds are qualified U. Non-detected compounds are not qualified. Sample concentrations reported below CRQL have been elevated to the CRQL. Acetone-P000l-SMITH-1101007-01, P0002-STEELE-191007-01, P0002-STEELE-191007- 02, P0003-DELEGARD-191007-01, and P0004-TILLET-101005-01 Toluene, ethylbenzene, o-xylene, m,p-xylene, and styrene were detected less than CRQL in the trip blank. Since, Toluene, ethylbenzene, o-xylene, m,p-xylene, and styrene samples results were non-detect in associated samples, no qualification was required. D) Storage Blank associated with VOA samples only: No problems were found for this criterion. ATTACHMENT 1 Page 4of6 E) Tentatively Identified Compounds: No problems were found for this criterion. 5. MASS SPECTROMETER TUNING: Tuning and performance criteria are established to ensure adequate mass resolution, proper identification of compounds and to some degree, sufficient instrument sensitivity. These criteria are not sample specific. Instrument performance is determined using standard materials. Therefore, these criteria should be met in all circumstances. The tuning standard for volatile organics is Bromofluorobenzene (BFB). If the mass calibration is in error, all associated data will be classified as unusable "R". Qualifications were applied to the samples and analytes as shown below. No problems were found for this criterion. 6. CALIBRATION: Satisfactory instrument calibration is established to ensure that the instrument is capable of producing acceptable quantitative data. An initial calibration demonstrates that the instrument is capable of giving acceptable performance at the beginning of an experimental sequence. The continuing calibration verifications (CCVs) document that the instrument is giving satisfactory daily performance. A) Response Factor GC/MS: The response factor measures the instrument's response to specific chemical compounds. The response factor for the target compound must be :::: 0.05, and :::: 0.01 for the poor performers in both the initial and opening continuing calibrations. For closing continuing calibration response factor for all target compounds must be :::: 0.01. A value < 0.05 for target compounds or < 0.01 for the poor performers indicates a serious detection and quantitation problem (poor sensitivity). Analytes detected in the sample will be qualified as estimated, "J". All non-detects for that compound will be rejected "R". No problems were found for this criterion. B) Percent Relative Standard Deviation (¾RSD) and Percent Difference (¾D): Percent RSD is calculated from the initial calibration and is used to indicate the stability of the specific compound response factor over increasing concentration. Percent D compares the response factor of the CCV to the mean relative response factor (RRF) from the initial calibration. Percent D is a measure of the instrument's daily performance. Percent RSD and ¾D must meet criteria listed in Table 2 of SOP HW-34A. A value outside of these limits indicates potential detection and quantitation errors. For these reasons, all positive results are flagged as estimated, "J". Non-detects are flagged "UJ" for ¾D values outside criteria only. If ¾RSD exceeds QC criteria, non-detects may be qualified using professional judgement. Qualifications were applied to the samples and analytes as shown below. No problems were found for this criterion. ATTACHMENT 1 Page 5 of6 7. INTERNAL STANDARDS PERFORMANCE GC/MS: Internal standards (IS) performance criteria ensure that the GC/MS sensitivity and response are stable during every experimental run. The internal standard area count must be in the range of 60% - 140 % of the associated continuing calibration internal standard from the associated continuing calibration standard. If the area count is greater than 140%, all positive results quantitated using that IS are qualified as estimated "J-", and non-detects are not qualified. If the area count is less than 60% of the associated standard, all positive results for compounds quantitated with that IS are qualified as estimated "J+" and all non-detects are qualified "R". If an internal standard retention time varies by more than 20 seconds, the reviewer will use professional judgment to determine either partial or total rejection of the data for that sample fraction. Qualifications were applied to the samples and analytes as shown below. No problems were found for this criterion. 8. FIELD DUPLICATES: . Sample pairs P0002-STEELE-191007-01 and P0002-STEELE-191007-02 were collected and analyzed as an overall indication of precision. This analysis measures both field and laboratory precision. A control limit of 20% for the Relative Percent Difference (RPD) will be used for original and duplicate sample values ~ five times (Sx) the Contract Required Quantitation Limit (CRQL). A control limit of the CRQL will be used if either the sample or duplicate value is < Sx the CRQL. For field duplicate analysis that does not meet the technical criteria, the action was applied to only the field sample and it's duplicate. Field duplicate sample pairs P0002-STEELE-191007-01 and P0002-STEELE-191007-02 yielded comparable results. 9. COMPOUND IDENTIFICATION: Target compounds are identified on the GC/MS by using the analyte's relative retention time (RRT) and by comparison to the ion spectra obtained from known standards. For the results to be a positive hit, the sample peak must be within a window of 0.06 RRT units of the standard compound and have an ion spectrum which has a ratio of the primary and secondary m/z intensities within 20% of that in the standard compound. For the tentatively identified compounds (TIC) the ion spectra must match accurately. In the cases where there is not an adequate ion spectrum match, the laboratory may have provided false positive identifications. Qualifications were applied to the samples and analytes as shown below. For all TICs where there was a presumptive evidence of a match as compared to the reference spectra (>85% match), results were qualified as tentatively identified (NJ) with approximated concentrations. TICs identified and reported by the laboratory with a poor match compared to the reference spectra (<85% match) were changed to "Unknown" by the validator and results were qualified as estimated (J) (refer to qualified Form Is). ATTACHMENT 1 Page 6 of6 10. CONTRACT NON-COMPLIANCE: Due to software limitations, laboratory entered the incomplete sample numbers on Form Is. Data reviewer manually completed the sample numbers on Form is and initialed it 11. FIELD DOCUMENTATION: The Chain-of-Custody was reviewed; no problems were found. 12. OTHER PROBLEMS: Tetrachloroethene concentration exceeded the calibration range in sample P0004-TILLET- 101005-0 l. The concentration of the tetrachloroethene was reported from the dilution analysis (P0004-TILLET-101005-01DL). 13. DILUTIONS, RE-EXTRACTIONS & REANALYSIS: Samples may be reanalyzed after dilution, re-extraction and for other QC reasons.
