7. The soil type, color, odor, and amount of recovery will be recorded in the soil boring logs as described in Section 4 and Attachment 3 of this SOP. 8. Subsamples of the soil will be collected for volatile field screening in a soil jar, sealed with aluminum foil, or in a re-sealable plastic bag. After allowing the sample to sit for at least fifteen minutes, a calibrated PID or FID will be carefully inserted through the foil or bag to collect a volatile content reading. The reading will be recorded on the soil boring log. 9. At each location, hollow steel direct-push rods equipped with a disposable tip and a section of slotted PVC will be advanced to the groundwater sample depth. Once the bottom of the target sample depth has been reached, the rods will be retracted, exposing the slotted PVC screen over the target sample interval while the disposable tip remains stationary. Groundwater samples will be collected with a new disposable polyethylene bailer or clean polyethylene tubing and peristaltic PUMP. 10. Groundwater samples will be collected with a new disposable polyethylene bailer or clean polyethylene tubing and peristaltic pump. The water quality will be monitored using a calibrated multi-parameter water quality measurement device. Groundwater samples will be collected directly into the appropriate laboratory supplied sample containers from the bailer or the peristaltic pump tubing before it goes through the multi-parameter probe flow through cell. Samples will be collected as outlined in the QAPP. Observations will be recorded on the field form in Attachment 4. 11. Upon completion of the soil boring, the drilling subcontractor will abandon the boring in accordance with the Department of Water Resources (DWR) Well Bulletin and local regulations specified by the boring permit,using a grout mixture that consists of Type II to V Portland cement, bentonite powder, and water. The grout mixture will be prepared aboveground, and the boring will be backfilled to at least 2 feet bgs. If the soil boring extends below the water table or is deeper than 30 feet bgs, a tremie pipe will be used to pour grout, otherwise the grout mixture may be allowed to free-fall into the boring. After backfilling,the location will be restored to pre-investigation conditions to the extent possible. 12.Non-disposable equipment or tools that may have come into contact with subsurface soil will be decontaminated. All disposable equipment used during sampling activities will be disposed of in a designated location. Soil cuttings and purged groundwater will be stored in drums and disposed of under proper waste manifest protocol, as described in Section 4 of this SOP. 5
