San Joaquin StreetLP <br /> P.O. Box 388 <br /> Stockton, California 95201 <br /> Attn: Mr. Michael .Infurna, R.E.H.S. <br /> Senior Health Specialist <br /> Dear Michael: <br /> We are forwarding two (2) copies of the Work Plan in connection with the Phase II <br /> Environmental Assessment to be conducted at the American Savings Bank's property at 222 <br /> North El Dorado Street, Stockton, California. <br /> The primary objective of the investigation is to determine if the subsoils at the property site <br /> have been impacted by petroleum hydrocarbons and volatile organics resulting from the site's <br /> former use as an auto service station and associated auto businesses. Since there are potential <br /> off-site sources, the groundwater beneath the property will also be investigated. <br /> We plan to drill and sample five (5) boreholes by using the Geoprobe System of coring and <br /> sampling. Three (3) of the boreholes will be advanced within the saturated zone to obtain <br /> groundwater samples. <br /> The soil samples will be analyzed for TPH and TEH by EPA 8015 Modified; and volatile <br /> organics by EPA 8260. Groundwater samples will be analyzed for TPH as gasoline and <br /> diesel, BTEX and VOCs. The groundwater monitoring well presently onsite will be sampled <br /> at the same time I will be in contact with you when we get closer to the permitting stage of <br /> this proposal. <br /> Thank you for all the assistance you have extended to us. <br /> Sincerely, <br /> CRC Environmental Risk Management, Inc. <br /> R nnie Almero, M.S R.E.A. #3376 <br /> Pr ject Manager <br /> cc: Trevor Santochi, CRC <br /> S:\SPT:\RONNIE\SANJOAQ.LET <br /> jl <br />
