Recently, Mr. Peters has resolved his financial difficulties and resumed investigation and <br /> monitoring of the site. Upgradient monitored and sampled the wells on November 17, 1997. <br /> 3.0 MONITORING PROCEDURES <br /> Upon arrival at the site, Upgradient personnel opened the wells and allowed them to equalize with <br /> air pressure. Approximately 15 minutes after opening,the depth to groundwater was measured with <br /> a Solinst water level meter. The water depths are shown in Table 1 and Appendix A. <br /> A two-stage submersible pump was then used to purge the wells of standing water, which was <br /> deposited in 55-gallon drums. During purging, the temperature, pH, and conductivity of the water <br /> were measured at 2-gallon intervals with a Corning Checkmate meter until these parameters <br /> stabilized (see Appendix A). To prevent cross-contamination, the pump -was washed in a TSF <br /> solution between wells. The water samples were collected with a disposable plastic bailer and <br /> placed in 40-m1 vials. The vials were labeled and logged, placed in a cooled ice chest, and shipped <br /> under chain-of-custody documentation to McCampbell Analytical for analysis. The chain of <br /> custody and laboratory report are included in Appendix B. <br /> 4.0 RESULTS <br /> • �,.! IDs W�"�to Gro�:�����er <br /> Groundwater has risen since 1995 by as much as four feet. At the present time, the depth averages <br /> approximately 12.5 feet. The elevation of the water table is slightly more than 10.5 feet below mean <br /> sea level. <br /> 4.2 Groundwater Gradient <br /> The data in Table 1 were used to calculate the groundwater gradient and determine the flow <br /> direction, which are illustrated in Figure 3. The present gradient is N52°E' at 0.00178 ft/ft. Since <br /> monitoring began in 1995,the direction has ranged between this and S72°E. <br /> Groundwater elevation data were collected in August 1997 by Blaine Tech at the former Chevron <br /> site across Franklin Street, and the gradient map constructed by Blaine Tech from that data also <br /> indicates that groundwater flow is to the northeast, toward the Kwikee Foods site. <br /> 3 <br />
