Tutu. St Thomas. U.S. Virgin Islands Dear Ms. Kwan: Per our telephone conversation on April 5, 1995, the initial sampling of the soil venting pile at the O'Henry Laundry, Tutu, St. Thomas is scheduled to take place the second week of May, 1995. I will call you with the actual dates of field sampling when they are finalized. The soil pile consists of two soil layers with each layer divided into quadrants by the venting pipes ( Figure 1). One discrete soil sample will be collected from the approximate center of each quadrant in each layer with the depth of the sample to be determined as described below. A total of eight samples will be collected from the soil pile. In order to ensure reliability of field sampling procedures and materials, quality control (QC) samples will be collected or prepared. QC samples will include one field duplicate, one trip blank and an equipment rinsate sample. Samples will be analyzed for EPA's Target Analyte List VOCs according to EPA's CLP March 1990 SOW. All data will be validated. It is anticipated that stainless steel auger buckets will be used for soil sample collection. Samples will be collected continuously through each layer at each location and headspace measured for VOCs using PID. The sample with the highest headspace for each layer at each location will be sent to the laboratory for analysis. Soil removed from the pile, but not sent to the laboratory for analysis will be placed back in the pile at the location from where it was removed. A final determination of the sampling equipment will be made after an IT representative has examined the roof structure over the soil venting pile. A site visit is scheduled to take place the week of April 17th, 1995. Decontamination procedures for soil sample collection equipment will be similar to the procedures followed during soil remediation efforts in accordance with the Work Plan for O:\B\Apr\AM002\bf Regional Office 312 Directors Drive • Knoxville, Tennessee 37923-4799 • 615-690-3211 • FAX: 615-690-3626 IT Corporation is a wholly owned subsidiary ot Internationa!
