Charter Way, Stockton, California <br />Dear Ms. Turkatte: <br />This letter report is submitted by Ground Zero Analysis, Inc. (Ground Zero) on behalf of Mr. Mark <br />Ranuio to summarize field activities and analytical results of soil and groundwater sampling at the <br />subject site. The work was conducted at the request of Wells Fargo Bank to explore the potential <br />presence of subsurface contaminants at the site. The location of the site is shown on Figure 1. <br />BACKGROUND <br />The site is located at the northeast corner of Charter Way 'and Fresno Avenue in Stockton, California. <br />The site previously housed three underground fuel storage tanks (one 500 -gallon, one 1000 -gallon, and <br />one 5000 -gallon capacity) which were reportedly operated by Signal Oil Company and Bill's Bait Shop. <br />The tanks were reported located beneath the dispenser island and were reportedly abandoned in place <br />by filling with slurry in 1981. k <br />In August 1989 Uriah Environmental of Livermore, California was- retained to explore potential <br />subsurface contaminants. A total of 12 exploratory soil borings were advanced to collect soil and water <br />samples from beneath the site. Analytical results indicated that soil had been moderately impacted by <br />petroleum hydrocarbons. Tabulated contaminant concentration data from that investigation is included <br />in Attachment A. <br />Following removal of the tanks, approximately 1530 cubic yards of soil were excavated under the <br />supervision of Uriah Environmental in 1990 to remediate contaminated soils beneath the site.
