MBiaoDs or SAMKS ation of a sample is the process of nixing individual grab oaaar to minimise any bias of sample representativeness intrednoea by the natural stratification of constituents within the sample. To homogeniae a sample of a soiVsediasnt matrix, first recks, twigs, leaves and other debris should be removed if they ore not considered pert of the sample, fee eoil/sedinent should be removed frcn the sampling davioe and placed in a stainless steel pan, then thoroughly mixed vising a stainless steel spoon. The PHI!leant in the pan should be scraped from the sides, comers and botton of the pan, railed to the middle of the pan, and initially mixed. The sample should then be 'ijuaraaKas. and moved to the four corners of the pan. Bach quarter of t±» sample should as nixed individually, and then rolled to the center of the container and the sulls* sample mixed again. tlanpqanization of an aqueous sample is only necessary if stratification <af CSOsTBp^pAi^"UOrt^i^p ^^SJ OX* C3C3HC3BCD • JDQ^f CfiC3BQ9&w>«l mHidJ jHBflUSjL JUTI3F flL MflkCVOGs^ COf liquid, then hanucjmization would be performed by mixing in a stainless bowl. B. compositing of samples is performed when samplers desire to obtain an concentration of contaminants over a certain number of sampling points, compositing is performed, the concentration of ccntaminant in individual samples is diluted proportionately to the number of samples taken. Nob c the contaminant diluted, the detection limits for each individual sample are proportionally to the number of samples added to the composite. Pbr : a sampler wishes to composite two discreet samples into one, and detection limit for a taxgatoompound is 33O ppb, the detection^ llait targst compound doss not change for the cmyosits, howsvar, the dstoacti for the compound in tfce individual samplaw Khlcfa make up tba iBesjii.'isite is ivnl the normal detacticn limit or 2 * 330 - WO ppb. rmis fa important to feaef in sasji it is possible that if a contaminant ware pvaaanl in only ana of liai iam lited asmpOM! and if it wan at a level between 330 and 640 would not be quantified or possibly even identified <*» effective dilution of the contaminant oonoantxation in tae ooRDosi'bB* should be taken into account *hen determining the data gjuality objeetivaa composite sampling ttvant, to ensure ttoat lawful data im oolleeted.
