Programmatic Sampling and Analysis Plan Project Number:60657245 6. Sampling Containers, Preservation, Packaging, and Shipping 6.1 Soil Samples PFAS - Soil samples will be analyzed for PFAS and collected in 4-ounce jars. The samples will be chilled to <6°C immediately upon collection. The container and preservative requirements are outlined in Section 4.1 and sample documentation will be followed as outlined in Section 8. 6.2 Water Samples PFAS —Water samples will be analyzed for PFAS and collected in 2x250-millilter HDPE bottles. The samples will be chilled to <6°C immediately upon collection. General Chemistry — Water samples will be analyzed for the alkalinity, anions, and total dissolved solids (TDS) in unpreserved containers. The samples will be chilled to <6°C immediately upon collection. Metals — Water samples will be analyzed for metals and collected in 500 mL HDPE bottles preserved with nitric acid. The samples are not required to be chilled, however, they may be placed in coolers with ice along with the samples collected for other analyses. The container and preservative requirements are outlined in Section 4.1 and sample documentation will be followed as outlined in Section 8. 6.3 Packaging and Shipping Upon collection and labeling, samples shall be packed for delivery to the assigned laboratory. Until shipment, sample integrity will be maintained in the field by AECOM field personnel using appropriate sample handling procedures. Specifically, appropriate sample preservation techniques (e.g., chemical preservations, stored in coolers with ice) will be applied to collected samples, samples will be packaged to prevent breakage or cross-contamination, and samples will remain under the control (e.g., within sight, locked storage) of the Field Sampling Team until custody is relinquished to the overnight delivery service. If samples are held overnight, sufficient ice (if necessary)will be added to the cooler to maintain the required preservation temperature of <_6°C, and the coolers will be kept in a locked, secure location. When transporting samples by vehicle, the following steps should be completed: • Select a sturdy cooler in good condition. Secure and tape the drain plug with duct tape both inside and outside. • Be sure the caps on all bottles are tight (will not leak); check to see that labels and chain-of-custody records are completed properly. • Place all bottles in separate and appropriately sized plastic zip-top bags and close the bags. Double bag all soil samples. Bottles may be wrapped in bubble wrap. It is preferable to place glass sample bottles and jars into the cooler vertically. • Place ice and sample containers in a large garbage bag(s)and properly seal with tape. Double bag with garbage bags and properly seal with tape. • Place the completed chain-of-custody form into a plastic zip-top bag, tape the bag to the inner side of the cooler's lid, and then close the cooler.
