Stockton, California <br /> Dear Ms. Lewis: <br /> On behalf of Western Farm Service, Inc. (WFS) GeoSyntec Consultants <br /> (GeoSyntec) submitted the Results of 2003 Semi-Annual Groundwater Monitoring and <br /> 2003 Annual Monitoring Report to the Regional Water Quality Control Board <br /> (RWQCB) on 31 October 2003. In the report, WFS recommended that the analysis of <br /> groundwater samples for chlorinated herbicides by EPA 8151 be reduced from Semi- <br /> annual to annual, and that isoconcentration contour maps be replaced with posted data. <br /> On 30 December 2003, the RWQCB issued a draft Monitoring and Reporting Program <br /> (MRP) incorporating some of the recommended changes. This letter comments on the <br /> draft MRP. <br /> We accept the changes made to the MRP, with the following exceptions: <br /> We recommend that the description of site ownership in the first sentence of <br /> the first paragraph be revised as follows: "The agricultural chemical facility <br /> at 1905 North Broadway Avenue in Stockton (site) was owned by Unocal <br /> until February of 1993. At that time, it was purchased by Crop Production <br /> Services (CPS), which was owned by Agrium.
