WVDP Phase 1 CSAPare a concern, then the analyte list for all remaining samples from this area will bemodified to include those contaminants.• If systematic sediment samples from Erdman Brook indicate contamination near to orabove sediment CG w levels at the boundary of the area of concern being sampled,systematic sampling will be extended to the balance of Erdman Brook within the WVDPpremises.• If the biased sample from Franks Creek indicates contamination near to or abovesediment CG w requirements, systematic sampling will be conducted along the balance ofFranks Creek within the WVDP premises.• If systematic surface soil samples exceed sediment CG w requirements, sampling willcontinue to depth until the encountered contamination is vertically bounded, andsampling will continue laterally until contamination is laterally bounded.J.10 ReferencesDOE 2009.
