MONITORING AND REPORTING PROGRAM 5 <br /> FOR CITY OF STOCKTON <br /> FRENCH CAMP LANDFILL <br /> CLASS III LANDFILL <br /> SAN JOAQUIN COUNTY <br /> Ground water sampling shall also include an accurate determination of the ground <br /> water surface elevation and field parameters (pH, temperature, electrical conductivity, <br /> turbidity) for that Monitoring Point or Background Monitoring Point. Ground water <br /> elevations taken prior to purging the well and sampling for Monitoring Parameters <br /> shall be used to fulfill the ground water gradient/direction analyses required. For each <br /> monitored ground water body, the Discharger shall measure the water level in each <br /> well and determine ground water gradient and direction at least quarterly, including <br /> the times of expected highest and lowest elevations of the water level for the <br /> respective ground water body. Ground water elevations for all background and <br /> downgradient wells for a given ground water body shall be measured within a period <br /> of time short enough to avoid temporal variations in ground water flow which could <br /> preclude accurate determination of ground water gradient and direction. This <br /> information shall be included in the quarterly monitoring reports. <br /> Statistical or non-statistical analysis should be performed as soon as the monitoring <br /> data are available. <br /> 3. Ground Water Monitoring <br /> Field and laboratory tests shall be reported in the quarterly monitoring reports. All <br /> Monitoring Parameters shall be graphed so as to show historical trends at each well. <br /> The ground water surface elevation (in feet and hundredths. M.S.L.) in all wells shall be <br /> measured on a quarterly basis and used to determine the velocity and direction of ground <br /> water flow. This information shall be displayed on a water table contour map and/or <br /> around water flow net for the site and submitted with the quarterly monitoring reports. <br /> The evaluation monitoring network shall consist of monitoring wells MW-1. MW-2, M-3, <br /> MW-4, and MW-5. Locations of these wells are shown on Attachment B attached hereto <br /> and made a part hereof. Ground water samples shall be collected from all wells and <br /> analyzed at the frequency and for the parameters specified in Table II. <br />
