Ms. Frances Schmiedt 2 - 15 September 2004 • <br />Each of the groundwater samples needs to include analysis for 1,2-dichloropropane and 1,2,3- <br />trichloropropane by EPA Method 8260. <br />Soil samples in the area of MW-2 must be analyzed for dieldrin by EPA Method 8081A. <br />The Work Plan proposes quarterly reporting for groundwater monitoring reports. Semi-annual <br />reporting is sufficient for this site. <br />Based on the schedule provided in the Work Plan, by 17 December 2004, please submit an <br />investigation report detailing the soil sampling as proposed along with recommendations for additional <br />work if needed. The first semi-annual groundwater monitoring report for the fourth quarter of 2004 <br />and the first quarter of 2005 is due by 1 May 2005. If you have any questions, you may contact me at <br />(916) 464-4719 or by email at lewisd@rb5s.swrcb.ca.gov. <br />(g—f2)U-Jte(_2-4.W_;LO <br />DEVRA LEWIS <br />Environmental Scientist <br />cc: Mr. Steve Becker, Department of Toxic Substances Control, Sacramento <br />San Joaquin County Environmental Health Department, Stockton <br />Mr. Joe Wells, City of Manteca Public Works, Manteca <br />Mr. Rod Attebury, Esq., Neumiller & Beardslee, Stockton <br />Mr. Joseph Zelles, Kleinfelder, Stockton
