• If a hydropunch type sampler is not used, the boring will be extended 3 to 5 feet into the <br /> aquifer. The augers or drive casing will be pulled back to allow for water to enter the boring. <br /> If caving of the borehole occurs, temporary PVC casing may be lowered into the drive casing <br /> or hollow stem augers prior to retraction of the drive casing. <br /> • Groundwater will be sampled using a small diameter stainless steel or disposable <br /> polyethylene bailer. <br /> • Groundwater samples will be transferred from the fill end of the bailer(bottom) to appropriate <br /> size/type containers with the appropriate preservatives, as required by the project needs. <br /> Precautions will be taken to avoid capturing air bubbles in the samples. Sample containers <br /> will be labeled, wrapped in plastic bags and stored in a cooler, on ice. The water samples will <br /> be transported to aState-certified laboratory for the appropriate chemical analyses. <br /> Soil borings will be closed by filling to the surface with a cement/bentonite grout mixture, not <br /> exceeding 5% bentonite. The locations of each boring will be marked with spray paint. <br /> S.
