GROUND WATER SAMPLE COLLECTION <br /> Grab ground water samples were collected from soil borings PBI throu h PB 12 using new, clean, <br /> ' disposable plastic bailers. The augers were advanced to total depth, then pulled out approximately <br /> 5 feet to allow water to enter the boring. The bailer was lowered into the :)oring through the augers <br /> and allowed to fill with water. Samples were transferred into 40-m1EPA-approved VOA vials <br /> ' containing 0.5 ml 18% hydrochloric acid as a sample preservative, 500- plastic bottles without <br /> preservative and into one 1-liter amber bottles without sample preserva e, as appropriate for the <br /> desired analysis. Ground water sample containers were labeled with soil boring designation, date, <br /> time, and samplers initials. <br /> The preserved samples were logged on a chain-of-custody form, placed in a chilled container and <br /> transported to MAI and Cal Tech Environmental Laboratories (CT L), both DHS-certified <br /> laboratories for analysis. <br /> Advwced Ce Envkon UU4Inc. <br />
