Box 1810 <br /> Stockton, CA 95201 <br /> REVIEW OF2ND QUARTER 2004 MONITORING REPORT,HARNEY LANE SANITARY <br /> LANDFILL, SAN JOAQ UIN CO UNTY, FA CILITY NO. 5B390307001 <br /> We have reviewed the Harney Lane Sanitary Landfill, 2nd Quarter 2004 Groundwater and Surface <br /> Water Monitoring Report(Report). Based on our review, we find the report complies with Waste <br /> Discharge Requirements Order No. 96-139. <br /> We note your comments on further investigating the source of increased levels of constituents of concern <br /> in MW-4 downgradient from the water treatment ponds at the migrant farm labor camp. During our last <br /> inspection,we noted a groundwater well head. I recommend that water quality be gathered from this <br /> well, as well as drilling logs, screened interval and any other pertinent information as part of your <br /> investigation. We appreciate your efforts in this regard. <br /> We also note that chloride increases in groundwater are also occurring in upgradient well MW-1. We <br /> recommend that your investigation include farm practices using herbicides and pesticides on grape <br /> vineyards. Also, sources of irrigation wells that may be using groundwater from different aquifers that <br /> may have naturally higher chloride than the aquifer monitored at Harney Lane. We look forward to <br /> seeing the results of your research regarding this area of concern. <br /> If you have any questions,please contact me at 916-464-4737. <br /> A.
