While purging gr <br /> each well, the pli specific conductance, and volume of water purged was monitored. <br /> Approximately three well volumes of groundwater were evacuated from all sampled monitoring <br /> wells. <br /> The wells were sampled using disposable polyvinyl chloride bailers equipped with bottom- <br /> emptying valves. The sample was drained directly from the bottom valve into four 40-milliliter <br /> . i septums. The samples were stored on ice from the time of <br /> glass battles with teflon-lin <br /> k collection through delivery to Enseco, a California state-ceAffi laboratory' <br /> All groundwater produced during the sampling activity was removed from the site by Armour <br /> Petroleum Services. <br /> 3330REPORT%0Cr9tqnRt'r - - <br />
