Box 1810 <br /> Stockton, CA 95201 <br /> REVIEW OF 3RD Q DAR TER 2004 MONITORING REPORT,IL 4 RNEY LANE SA N'ITAR Y <br /> LANDFILL, SANJOA QUIN COUNTY, FACILITNO. 5B390307001 <br /> We have reviewed the Harney Lane Sanitary Landfill, 3rd 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 /> VOCs were detected in MW-2 as dichlorodifluoromethane, 1,2-dischloropropane, and tetrachloroethene. <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 at the migrant farm labor camp. I recommend that water <br /> quality be gathered from this well, as well as drilling logs, screened interval and any other pertinent <br /> information as part of your 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 and, <br /> according to the County, unexplained levels in MW-4. We recommend that your investigation include <br /> farm practices using herbicides, fertilizers, and pesticides on grape vineyards. Also, the County should <br /> investigate the 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 or schwabk@rb5s.swrcb.ca.gov. <br /> KIM/A.
