MONITORING AND REPORTING PROGRAM NO.R5-2002-0121 -5- FOR FORWARD INC. AUSTIN ROAD LANDFILL FACILITY CLASS III LANDFILL SAN JOAQUIN COUNTY Ground water sampling shall also include an accurate determination of the ground water surface elevation and field parameters (pH, temperature, electrical conductivity, turbidity) for that Monitoring Point or Background Monitoring Point. Ground water elevations taken prior to purging the well and sampling for Monitoring Parameters shall be used to fulfill the ground water gradient/direction analyses required. For each monitored ground water body, the Discharger shall measure the water level in each well and determine ground water gradient and direction at least quarterly, including the times of expected highest and lowest elevations of the water level for the respective ground water body. Ground water elevations for all background and downgradient wells for a given ground water body shall be measured within a period of time short enough to avoid temporal variations in ground water flow which could preclude accurate determination of ground water gradient and direction. This information shall be included in the quarterly monitoring reports. Statistical or non-statistical analysis should be performed as soon as the monitoring data are available. 3. .Leachate Monitoring Program If leachate surfaces, the discharger shall immediately sample the leachate and continue to sample and report the leachate at the frequencies listed in Table I thereafter. Also, should a Leachate Collection Removal System be constructed, it shall be monitored according to the schedule in Table I. For COC detection, the leachate sump will be sampled in the fourth quarter of the year in which it is constructed, for the parameters and frequencies in Table I. Those COCs that are detected will be analyzed in leachate in the second quarter of the year following the year of construction. Any COCs detected in the retest sample shall be included in the COC list for ground water, surface water and unsaturated zone. Thereafter, leachate samples for COC detection will be collected annually in the fourth quarter of the year. If constituents are detected that are not already CDCs, leachate will be resampled for those constituents only in the second quarter of the following year. If the COC is detected in the retest sample it shall be added to the list of COCs in the ground water monitoring program, the surface water monitoring program, and the unsaturated zone monitoring program.
