Box 3006 <br /> Lodi, CA 95241-1910 <br /> GROUNDWATER MONITORING STATUS REPORT, CITY OFLODI, WHITE SLOUGH= <br /> WATER POLLUTION CONTROL FACILITY, SANJO,4QL1V COUNTY <br /> We have reviewed the Groundwater Monitoring Status Report received 25 July 2003. We recognize the <br /> status report is preliminary, however we have the following comments: <br /> 1.' The report is not certified by the Discharger as required by the Standard Provisions; <br /> 2. Specific Conductivity and Total Coliform Organisms are groundwater constituents that were <br /> measured for the groundwater-monitoring program. However, it appears that these data have <br /> been overlooked. No mention is made as to why these constituents have been excluded from the <br /> status report evaluation; <br /> 3. The report does not present the constituents cumulative data in a tabular format for easy review; <br /> 4. Groundwater flow gradient and direction are not calculated or graphically presented. The <br /> calculation and presentation are required by the Monitoring and Reporting Program <br /> No. 5-00-031; and <br /> 5. Figures 4 and 5 show areas where nitrogen was added in surplus over the estimated annual crop <br /> uptake. The surplus may have contributed to nitrogen percolating into groundwater. Nitrogen <br /> percolation to groundwater appears to be an explanation for Figures C3 through C9 contained in <br /> Appendix C indicating a nitrogen anomaly in the same area. The report does not fully explain <br /> the anomaly presence. Instead, Conclusion 9 states no significant impact from the treatment <br /> plant operations on groundwater. Also,the no impact conclusion is presented without any <br /> presentation, evaluation, or discussion to support excluding Specific Conductivity and Total <br /> Coliform Organisms from the groundwater quality analysis. Therefore,water quality has not <br /> California Environmental Protection Agency <br /> Ca Recycled Paper <br /> The energy challenge facing California is real.
