uu.e ta,u. <br />• <br />4.2 Sample Collection <br />After three casing volumes had been purged from each well, and the temperature and pH had <br />stabilized, monitoring personnel donned clean disposable latex gloves and began sampling. Two <br />40m1 VOA vials were collected first, with care taken to avoid collecting headspace bubbles. The <br />remaining bailer volume was split between two 1 liter sample bottles. Subsequent bailer volumes <br />were also split between the two sample bottles. One oC the bottles was submitted to the <br />laboratory for analysis oC dissolved metals, while the second was analyzed for anions, pH, <br />alkalinity, specific conductance, turbidity, total dissolved solids, and total suspended solids. The <br />ground water samples were stored in a cooler on ice, and delivered to Evergreen Analytical, Inc., <br />Cor analysis. The bailer was carefully cleaned after sampling each well using non-phosphate <br />soap, hexane, and triple rinsed with deionized water. The nylon bailer rope was discarded after <br />sampling each well. <br />4.3 Surface Water Sample Collection <br />Af[er ground water sampling was completed, monitoring personnel performed surface water <br />sampling. Typically, two 40m1 VOA vials were immersed first, followed by the two 1 liter <br />bottles. Sampling personnel changed cloves after each sampling location. The surface water <br />• samples were stored on ice in a cooler with the ground water samples. <br />4.4 Sample Labeline <br />Ground water samples collected Crom monitoring well DFMW-1 were labeled: <br />DFMW - l l Volatile organic analysis (VOA) <br />12 VOA <br />IS anions, pH, alkalinity, specific conductance, turbidity, total <br />dissolved solids (TDS) and total suspended solids (TSS). <br />16 Dissolved metals <br />P~ojed N~bc 7e9-LL1-013 <br />• ]uly 73, 1990 <br />Page S <br />
