Cherokee Lane Lodi, CA 95240 ENVIRO! ENTAL HEALTH F ERMIT/SERVICES, Dear Mr. Johnson: As promised in the environmental assessment work plans for the Douglas station in Lodi, CA, I am submitting a, proposal of alternative remedial actions to re- cover the petroleum hydrocarbon on the unconfined groundwater and the adjacent soils. Implementation of the remedial actions shall begin after the necessary approvals are received. The following is •a description of the current hydrological conditions at the station which shall determine the alternatives available to mitigate the con- tamination discovered. The alternatives provided are based on the conclusion that there is no detectable or free product in any of the groundwater monitor- ing wells. However, the alternatives do describe specific methods to remediate the present contamination. SITE CONDITIONS On June 21, 1985, Fox Environmental Services, Inc. reported the groundwater depth to be7.;-50.958 feet for MW-1, 51.916 feet for MW-8, and 51.0 feet for MW-9. It was also reported that a minimum of 2.79 feet of free product was present in MW-8 as of that date. The product has been bailed to a non-progres- sive condition at each monitoring visit. Five additional groundwater monitoring wells have been installed to further define the aerial and vertical extent of the product discovered in MW-8. The installation technique and the location of these wells were reported in the September 4, 1985, work plan. Nevertheless, Figure 1 is a diagram of the station and the location of the monitoring wells installed by Fox Environmental Services and I. T. Corporation.
