WVDP Phase 1 CSAP• Depending on the outcome of the first round of systematic soil sampling, additionalsystematic soil sample locations will be selected to further laterally bound contaminationextent.• If contamination above background levels is encountered in any 15 cm-1 m soil interval,additional deeper 1-m interval soil samples will be required for that location to determinevertical extent of contamination. If additional vertical samples are required, verticalsampling will continue until background conditions are observed.I.10 ReferencesDOE 2009.
