Box 4267 <br /> Stockton, CA 95204-0267 <br /> FIRST SEMI-ANNUAL 2004 GROUNDWATER MONITORING, FORMER SPRECKELS <br /> SUGAR PLANT NO. 2, SAN JOAQUIN COUNTY (CASE NO. 860) <br /> We have reviewed the First Semi Annual 2004 Groundwater Monitoring Report, Former Spreckels <br /> Sugar Plant No. 2 submitted on 30 August 2004 by Kleinfelder Inc. on behalf of AKF Development <br /> LLC. <br /> The enclosed Monitoring Report Compliance Checklists summarizes our comments on the report. The <br /> report is complete. <br /> Monitoring results since closure of the lime ponds demonstrate a steady decrease of constituents of <br /> concern (pollutants) in groundwater. Although, an identifiable body of impacted groundwater remains <br /> northwest of the former pond area, the extent of impacts have decreased and concentrations are lower. <br /> In light of the success of corrective actions at your site,the 2004 annual report should propose <br /> revisions to the Monitoring and Reporting Program. Trend analysis may be used to estimate time to <br /> reach tolerance limits, drinking water MCLs and/or average groundwater background concentrations <br /> for selected constituents and possibly justify changes to monitoring requirements. <br /> If you have any questions about what should be in the annual report please call me at (916) 464-4614. <br /> ROSS D.
