electronic probe, from the mark located on the top of each casing. <br /> • The resulting data is shown in Table 2 . Depth to groundwater <br /> measurements were made prior to repair of MW-3 as discussed below. <br /> TABLE 2 <br /> Groundwater Elevation measurements - September 25, 1995 in Feet <br /> Well ID Well Elevation Depth to Water Groundwater <br /> Elevation <br /> MW-1 12 . 07 10. 46 1. 61 <br /> MW-2 12 .89 11. 20 1. 69 <br /> MW-3 11.75 10. 61 1. 14 <br /> .I The calculated gradient is 2970 at 0 . 01 ft/ft. <br /> Groundwater Sampling <br /> Close observation of MW-3 indicated that the casing and stovepipe <br /> protecting the well had been inadvertently hit. The casing had a <br /> crimp an it and would allow neither the pump nor bailer to get to <br /> the groundwater. JPCA, with an agreement with the owner, repaired <br /> he casing and reset the stovepipe in cement. <br /> . The wells were developed by pumping, purging and collecting the <br /> purged groundwater in 55-gallon drums labeled awaiting analysis. <br /> Each of the wells was pumped to dryness. The wells were slow in <br /> recovering as they were in the previous sampling event. Well data <br /> sheets are contained in Appendix A. <br /> The pump was decontaminated using tri-sodium phosphate solution <br /> (TSP) and twice rinsed with the last rinse using distilled water <br /> prior to being used in each well. <br /> Three groundwater samples, one from each well , was collected by a <br /> clean dedicated bailer, placed in two 40 ml VOAs with Teflon septa, <br /> labeled, held in a cooled (4 Degrees C) ice chest and transported <br /> to a State Certified Laboratory, under COC documentation, for <br /> analyses. The samples from Monitoring wells MW-1 and MW-2 were <br /> collected on September 25, 1995 and from Monitoring well MW-3 on <br /> September 26, 1995 after the well casing was repaired. <br /> The groundwater pumped from MW-1 had a slight hydrocarbon odor. No <br /> odor was observed in the groundwater at MW-2 . MW-3 had a <br /> noticeable odor after the water was pumped. <br /> • 4 <br />
