MONITORING AND REPORTINGOOGRAM NO. 5-00-142 -5 - <br /> CITY OF ESCALON <br /> WASTEWATER TREATMENT PLANT <br /> SAN JOAQUIN COUNTY <br /> supported by field logs for each well documenting depth to groundwater; parameters <br /> measured before, during, and after purging; method of purging; calculation of the casing <br /> volume; and total volume of water purged. <br /> 2. Calculation of groundwater elevations, an assessment of the groundwater flow direction and <br /> gradient on the date of measurement, comparison to previous flow direction and gradient <br /> data, and discussion of seasonal trends, if any. <br /> 3. A narrative discussion of the analytical results for all media and locations monitored, <br /> including spatial and temporal trends, with reference to summary data tables, graphs, and <br /> appended analytical reports (as applicable). <br /> 4. A comparison of monitoring data to the discharge specifications, groundwater limitations, <br /> and surface water limitations, and explanation of any violation of those requirements. <br /> 5. Summary data tables of historical and current water table elevations and analytical results. <br /> 6. A scaled map showing relevant structures and features of the facility, the locations of <br /> monitoring wells and other sampling stations, and groundwater elevation contours <br /> referenced to mean sea level datum. <br /> 7. Copies of laboratory analytical report(s). <br /> C. Annual Report <br /> An Annual Report shall be prepared as the fourth quarter monitoring report. The Annual <br /> Report will include all monitoring data required in the monthly/quarterly schedule. The Annual <br /> Report shall be submitted to the Regional Board by 1 February each year. In addition to the <br /> data normally presented, the Annual Report shall include the following: <br /> 1. If requested by Staff, tabular and graphical summaries of all data collected during the year. <br /> 2. An evaluation of the performance of the domestic wastewater treatment system and <br /> evaporation/percolation ponds, as well as a forecast of the flows anticipated in the next year. <br /> 3. An evaluation of the performance of the industrial wastewater treatment system and <br /> evaporation/percolation ponds, as well as a forecast of the flows anticipated in the next year. <br /> 4. An evaluation of the groundwater quality at the wastewater treatment facility. <br /> 5. A summary data table of water levels and freeboard in the storage ponds. <br /> 6. A discussion of compliance and the corrective action taken, as well as any planned or <br /> proposed actions needed to bring the discharge into full compliance with the waste <br /> discharge requirements. <br />
