Programmatic Sampling and Analysis Plan Project Number:60657245 <br /> 3. Sampling Design and Rationale <br /> The following is a description of the rationale for collection and analysis of soil and water samples. <br /> The proposed sampling locations for surface and subsurface soil, influent, effluent, groundwater, <br /> and/or stormwater as identified as where PFAS may be currently and/or may have been <br /> historically released. <br /> Soil Sampling <br /> Soil samples will be analyzed for PFAS as noted in Section 4.1. <br /> Groundwater Sampling <br /> Groundwater samples will be analyzed for PFAS, general chemistry, and metals as noted in <br /> Section 4.1. <br /> Stormwater Water Sampling <br /> Stormwater samples will be analyzed for PFAS, general chemistry, and metals as noted in <br /> Section 4.1. <br /> 3.4 Wastewater Sampling <br /> Influent Sampling <br /> Influent sampling will be required at facilities with an onsite wastewater treatment plan. Influent <br /> samples will be collected from location prior to any treatment and representative of all wastewater <br /> associated with the facility's industrial discharge. <br /> Two influent samples will be collected; one sample representing the facility's un-treated <br /> wastewater and one sample representing the stormwater commingled with the untreated <br /> wastewater (if applicable). <br /> Effluent Sampling <br /> Effluent sampling will be required at facilities with an onsite wastewater treatment plant. Effluent <br /> sample locations must represent the treated wastewater associated with the facility's industrial <br /> activities. <br /> Wastewater samples will be analyzed for PFAS, general chemistry, and metals as noted in <br /> Section 4.1. <br /> AECOM <br /> 10 <br />
