Groundwater constituents of concern include nitrate, ammonium, atrazine,bromacil, dinoseb, 1,2-dichloropropane (1,2-DCP), 1,2,3- trichloropropane (1,2,3-TCP), and other constituents. On behalf of the other operators, Miller Springs Remediation Management(MSRM) is coordinating the investigation and remediation of the site. Central Valley Regional Water Quality Control Board (Regional Board) staff have reviewed the history of the site, distribution of constituents,remediation activities, analysis of additional remedial activities, and recommendations, as presented in the following reports prepared by Geomatrix Consultants: • April 2002 LTTD Soil Remediation Report • September 2003 Feasibility Study/Remedial Options Evaluation Report for Groundwater Remediation (FS/RO) • October 2003 Second Semiannual and Annual 2003 Monitoring Report • February 2004 Analyses for 1,2,3-Trichloropropane • April 2004 First Semiannual 2004 Monitoring Report Soil Remediation hi its 13 July 1999 Revised Feasibility Study for Soil Remediation, MSRM outlined a strategy to remediate soil at this site by excavating and treating the most contaminated area of soil, and establishing a phytoremediation plot to remediate nitrate and low concentrations of pesticides in soil in the remainder of the property. In late 2001, pursuant to its 13 June 2001 Soil Remediation Plan, Geomatrix Consultants excavated and successfully treated about 2,900 tons of contaminated soil with low temperature thermal destruction, as reported in the April 2002 LTTD Soil Remediation Report. In the summer of 2003, Geomatrix planted about 1,500 eucalyptus trees as proposed in its 8 November 2001 Phytoremediation Work Plan. The primary objective of the phytoremediation plot is to remove nitrogen from the soil column by biological uptake. A secondary objective is to accelerate degradation of residual pesticides in soil.
