The installation of these wells was proposed <br /> in the Preliminary Hydrogeologic Assessment Report submitted by <br /> Delta Environmental Consultants in September 1989. <br /> Following installation and development of these additional <br /> monitoring wells, all monitoring wells at the site will be sampled. <br /> Ground water samples will be submitted to a California-certified <br /> laboratory to be analyzed for ethylene dibromide (EDB) , 1,2- <br /> dichloroethane (EDC) , benzene, toluene, ethylbenzene, xylem <br /> (BTEX) , and total purgeable hydrocarbons (TPH) by EPA metho 60.�) <br /> Monitoring well installation, development, and sampling will follow <br /> those procedures and guidelines submitted previously in the <br /> Hydrogeologic Assessment Work Plan for this site. <br /> Laboratory turn-around time is typically 12 working days. I <br /> anticipate that a Problem Assessment Report addressing <br /> recommendations for further ground-water monitoring and remediation <br /> (if needed) can be forwarded to your office by July 31, 1990. <br /> If you have any questions, please give me a call. <br /> Sincerely, <br /> TRT GRTER ASSOCIATES <br /> Darrell L.
