Remedial Investigation QAPP Stockton Army Aviation Support Facility,California 14.2.13 Sample Handling, Storage and Transport Samples will be stored on ice, packaged, and submitted to the analytical laboratory for analysis as specified in Worksheet#15. Worksheets #17 & #18 provide the sampling design and rationale. Worksheets #17 & #18, Worksheets #19 & #30, and Worksheet #20 provide sample identifications, necessary sample volume and preservative requirements, and hold time limitations. Samples will be QC checked by the field team lead or designee (label correctness and completeness) and recorded on CoC forms. Samples will be packaged on ice and transported overnight by commercial carrier or a laboratory courier under standard custody procedures to the laboratory. See Parsons SOP PFAS ENV-10: Sample Handling, Storage, and Shipping (Appendix D) for additional information. 14.2.14 Field Documentation Sample collection information will be recorded in untreated bound field notebooks or specific field forms,and/or digital forms on tablet computers. If using a logbook or field form, an incorrect entry is made, striking a single line through the incorrect information will correct the text, and the person making the correction will initial and date the change. Sampling forms and other field forms will also be used to document field activities. Preference will be given for record keeping via digital forms as this allows for near real time data transfer back to the office and limits the likelihood for misplacing records. 14.2.15 Borehole Abandonment Unless they are being converted into monitoring wells, borings will be abandoned upon completion of sampling activities using grout mixed in accordance with county-specific requirements outlined in San Joaquin County Ordinance Code Section 9-1115.6,Well Standards(San Joaquin County,2005).Grouting will be performed using a tremie pipe advanced to the bottom of the hole, filling the borehole from the bottom to the top, removing sections of tremie pipe as the grout fills the borehole. If the boring is required in asphalt, it will be abandoned with grout to approximately 6 inches bgs,and the remainder of the borehole will be patched with an asphalt cold patch. Borings into concrete will be avoided, if possible, to minimize the introduction of foreign object debris. However, if borings are advanced into concrete, the borings will be abandoned with grout to approximately 6 inches bgs,and the remainder of the borehole will be filled with concrete to provide as flush a surface as possible. The surface at each location will be restored to match the surrounding area. See Parsons SOP PFASENV-05.Soil Borings and Monitoring Well Installation (Appendix D)for more details. 14.2.16 Facility Restoration Following well installation activities, the ground surface will be restored to match the surrounding area (e.g., seeded with grass if necessary). 14.2.17 Equipment Decontamination The team will utilize dedicated and disposable sampling equipment to the extent possible to avoid cross contamination due to inadequate decontamination processes. The dedicated/disposable sampling equipment will include disposable polyethylene tubing, disposable gloves, and laboratory-supplied sample bottles. Non-disposable or non-dedicated sampling equipment (e.g., water level meters, water quality meters, etc.) will be decontaminated prior to sampling and between sample locations. Decontamination will generally consist of a water rinse station to remove gross contamination, followed by a non-phosphate detergent (e.g., Liquinoxe) water rinse, a double rinse with water suitable for decontamination (Section 14.1.5), and a final rinse using lab PARSONS Worksheet#14&16: Project Tasks and Schedule Page 71
