R. Simplot Company(OCC) are investigating the extent of <br /> groundwater contamination resulting from 38 years of agricultural chemical distribution <br /> operations at 1904 Charter Way in Stockton. OCC conducts groundwater sampling from 25 <br /> monitoring wells at and downgradient from this site. We have reviewed the following reports <br /> prepared by Geomatrix, OCC's consultant, describing the results of the groundwater monitoring <br /> events. <br /> • October 1999 Second Trimester 1999 Monitoring Report <br /> • February 2000 Third Trimester 1999 Monitoring Report <br /> • May 20001999 Annual and First Trimester 2000 Monitoring Report(1999 Annual Report) <br /> • October 2000 Second Trimester 2000 Monitoring Report <br /> • February 2001 Third Trimester 2000 Monitoring Report <br /> • June 2001 2000 Annual and First Trimester 2001 Monitoring Report(2000 Annual Report) <br /> The monitoring reports are well written and contain a good description of the site history and <br /> investigations to date. The 1999 Annual Report additionally contains results of field tests and <br /> general mineral analyses that OCC performed on the groundwater for two years to assess the <br /> potential for bioremediation. The mineral analyses include nitrate, iron, manganese, and <br /> dissolved organic carbon. These can be compared to the field parameters of dissolved oxygen <br /> (DO) and oxidation reduction potential(ORP) to identify if biodegradation status could be <br /> approximated with either DO or ORP. This will be more important if OCC wishes to pursue <br /> bioremediation of groundwater. <br /> In the Third Trimester 1999 Monitoring Report, Geomatrix reports that a third party has <br /> validated the analytical data for four consecutive years and that the analytical laboratory <br /> satisfactorily meets objectives. This data validation is not required in Monitoring and Reporting <br /> California Environmental Protection Agency <br /> Q, Recycled Paper <br /> The energy challenge facing California is real.
