Programmatic Sampling and Analysis Plan Project Number:60657245 <br /> 4. Request of Analyses <br /> 4.1 Analyses Narrative <br /> Soil and water samples collected in the field will be submitted to California-approved laboratory <br /> Eurofins Lancaster. Sample container requirements and holding times are described in the <br /> following table: <br /> Table 4.1 —Sample Container and Holding Time Requirements <br /> Analytical Method Container Requirements Preservative Holding Time <br /> Soil Samples <br /> PFAS* 4 oz HDPE with Unlined Cool <_6°C 28 Days <br /> Screw Cap <br /> Groundwater Samples <br /> PFAS* 2x250mL HDPE with Cool <_6°C 14 Days <br /> Unlined Screw Cap <br /> SM2540C—Total Dissolved 1 L Amber Cool <_6°C 7 Days <br /> Solids <br /> USEPA 9056A—Anions: <br /> Chloride, Nitrate-Nitrogen, 500mL HDPE Cool <_6°C 48 Hours <br /> Sulfate <br /> SM 2320B—Alkalinity: 500mL HDPE Cool <_6°C 28 Days <br /> Bicarbonate, Carbonate <br /> SW-846 6010C— Metals: <br /> Calcium, Magnesium, 500mL HDPE HNO3, pH <2 180 Days <br /> Potassium, Sodium <br /> Stormwater Samples <br /> PFAS* 2x250mL HDPE with Cool <_6°C 14 Days <br /> Unlined Screw Cap <br /> *The PFAS analyte list is provided in Table 1. <br /> —Less Than mL—Milliliter <br /> <_—Less Than or Equal to oz—Ounce <br /> °C—Degrees Celsius PFAS—Per-and Polyfluoroalkyl Substances <br /> HDPE—High Density Polyethylene SM—Standard Methods <br /> HNO3—Nitric Acid USEPA—United States Environmental Protection Agency <br /> L—Liter <br /> 4.2 Analytical Laboratory <br /> Collected environmental samples will be analyzed by laboratories that have well-developed QA <br /> programs; the laboratory used to implement this SAP will be California approved to perform the <br /> analyses specified in Section 4.1. The analytical data will be generated by Eurofins Lancaster of <br /> Lancaster, Pennsylvania. Eurofins Lancaster is certified for the analyses specified in Section 4.1 <br /> and holds DOD ELAP accreditation. <br /> AECOM acknowledges that it understands and agrees to the measurement quality objectives <br /> defined by Eurofins Lancaster which will be used for the project. Laboratory QC measures for <br /> standards, blanks, calibration, analyte identification, and quantitation will be performed as <br /> specified by the analytical method, DOD QSM version 5.3 (DoD, 2019), this SAP, and Eurofins <br /> Lancaster's Quality Assurance Manual (available upon request). <br /> Soil and water reporting limits will be less than or equal to those reported in Table 1. <br /> AECOM <br /> 11 <br />
