WVDP Phase 1 CSAP• If the GWS results indicate areas that likely exceed surface soil CG w requirements, onelocation will be selected for sampling with the highest GWS results, and surface soilsample locations will be selected to laterally bound contamination.• If the GWS results are ambiguous with respect to surface soil CG w requirements, surfacesampling locations will be selected to clarify GWS results.• If systematic surface soil samples exceed background levels, sampling will continue todepth at those locations until the encountered contamination is vertically bounded.D.10 ReferencesDOE 2009.
