As noted during a telephone communication with Clearwater, the depth to <br /> groundwater did not range from 23.83 to 24.46 feet below top of casing, as reported. <br /> Depth to water measurements actually ranged from 15.93 to 17.34 feet. <br /> Groundwater samples were not collected from monitoring wells, MW1 and MW2, <br /> because product was observed at depths from 0.16 feet to a sheen, respectively. Please <br /> note that in the future, should free product be observed, efforts should be made to <br /> immediately initiate removal. <br /> The domestic well should be sampled during the next quarterly monitoring event and <br /> annually thereafter. Samples collected from monitoring wells, MW3 - MW7 did not <br /> detect petroleum hydrocarbon contamination, thereby defining the horizontal extent of <br /> the groundwater plume. <br /> During second quarter, April 7, 1995, additional wells were installed that included one <br /> recovery well, RW1 and two air sparge wells, SW1 and SW2. The results of soil <br /> sampling conducted during installation are yet to be reported. <br /> A Division of San Joaquin County Health Care Services <br />
