We have reviewed the following reports <br />prepared by your consultant, GeoSyntec Consultants: <br />• 1 May 2003 Results of 1 St Quarter 2003 Groundwater Monitoring (First QMR) <br />• 30 January 2003 2002 Annual Report and Results of Fourth Quarter 2002 <br />• 31 October 2002 Results of 3rd Quarter 2002 Groundwater Monitoring <br />• 1 August 2002 Results of 2`1 Quarter 2002 Groundwater Monitoring <br />The First QMR includes a work plan for downgradient delineation of groundwater pollutants and <br />proposes revisions to Monitoring and Reporting Program No. 5-01-818. <br />Downgradient Delineation <br />The work plan included in the First QMR proposes six off-site grab groundwater samples to <br />determine the extent of off-site migration of 1,2-dichloropropane (1,2-DCP), 1,2,3-trichloro- <br />propane (1,2,3 -TCP), and nitrate. GeoSyntec proposes to obtain the samples along South <br />Argonaut Way, north of the facility. This is downgradient of the highest concentrations of these <br />compounds that have been detected on-site. We concur with the sample locations, but there <br />remains a gap in the downgradient delineation between MW -4, MW -5, and South Argonaut <br />Way. In order to reduce the need for subsequent grab groundwater investigations, JTF should <br />add at least one grab groundwater sample near the northeast corner of the facility. <br />California Environmental Protection Agency <br />:tea Recycled Paper <br />The energy challenge facing California is real. Every Californian needs to take immediate action to reduce energy consumption.
