The work plan proposes to install a shallow monitoring well north of the <br /> Koppel Stockton facility in response to Central Valley Regional Water Quality Control Board(Regional <br /> Board) staff s 27 September 2004 letter requesting plume delineation to the north. <br /> Koppel proposes to install this monitoring well (MW-1 OS)in June 2005, and sample this well semi- <br /> annually in the first and third quarters (Jan-March and July-September) for nitrate and ammonium <br /> pursuant to Monitoring and Reporting Program No. R5-2004-0835. The rationale for installing <br /> MW-1 OS in June is to wait until the seasonally wet soils have dried sufficiently to support drilling <br /> equipment. <br /> We concur with the Work Plan as proposed. Please provide a Monitoring Well Installation Report as an <br /> Appendix t the Annual Groundwater Monitoring report, which is due I November 2005.
