Bank of America <br /> Environmental Services 24122 <br /> September 16, 1997 <br /> Mr. Steve Sasson <br /> Senior Registered Environmental Health Specialist <br /> San Joaquin County Public Health Services <br /> Environmental Health Division <br /> P.O. Box 388 <br /> Stockton, CA 95201-0388 <br /> Subject: Bank of America Ripon Branch <br /> 234 W. Main St., Ripon, CA <br /> Dear Mr. Sasson: <br /> Enclosed please find a copy of the final report for the Phase II subsurface investigation <br /> recently completed at the subject site. Please note that this copy is mistakenly <br /> designated as a "Draft"; however, it is a final report. In addition, I am enclosing a <br /> complete copy of the Phase II report for the subsurface site assessment completed in <br /> May 1997. <br /> As discussed in the report, no petroleum hydrocarbon constituents were detected in <br /> any of the soil samples collected during the investigation. Metal concentrations in soil <br /> samples were consistent with background levels for the area. <br /> Metal concentrations in grab groundwater samples were very low and well below the <br /> California Department of Health Services Primary Maximum Contaminant Levels for <br /> drinking water. No petroleum hydrocarbon constituents were detected in onsite grab <br /> groundwater samples. Very low concentrations of petroleum hydrocarbons were <br /> detected in offsite grab groundwater samples as follows: <br /> • 76-250 ug/L TPH-D in two offsite grab groundwater samples; and <br /> • 42.0 ug/L ethylbenzene and 41 .8 ug/L total xylenes in one offsite <br /> grab groundwater sample. <br /> Bank of America National Trust and Savings Association <br /> 4000 MacArthur Boulevard Suite 100 Newport Beach, CA 92660 Phone 714/260-5819 �� <br />
