' Corrective Action Plan Page 2 <br /> Former Manna Pro Site <br /> Project No 207 3 <br /> • February 16,2001 <br />' 1.1 Site History <br />' The former Manna Pro facility was originally constructed in 1956 as a grain mill, which <br /> processed animal feed products Two 10,000-gallon underground diesel tanks and two <br /> 5,000-gallon underground gasoline tanks and a single 10,000-gallon underground <br />' gasoline tank were formerly operated at the site The former tanks were located dust <br /> northeast of the main entrance to the Property from El Dorado Street <br />' In January 1990, as part of an environmental site assessment, WHF installed six soil <br /> borings near the tanks and soil samples were collected from the borings One soil <br /> sample, collected from 15 feet below grade, contained elevated levels of gasoline and <br />' diesel range hydrocarbons In July of 1990, Semco removed the tanks and petroleum <br /> hydrocarbons were detected in soil samples from beneath 4 of the 5 tanks Based on the <br /> results of this initial soil sample analysis, several hundred yards of fuel-impacted soil <br />' were excavated The excavation reached a total depth of about 15 feet <br /> In October of 1990, ERM West conducted additional work to characterize the lateral and <br />' vertical extent of the hydrocarbon contamination in the sub-surface This included <br /> installing 25 soil borings into groundwater of which, a total of 6 borings were later <br />'. converted to groundwater monitoring wells Between 1993 and 1996, Groundwater <br /> Technology Inc (GTI) installed four additional monitoring wells, a combination <br /> groundwater/vapor extraction well and three observation wells These wells were used <br />' for the completion of groundwater pumping and vapor extraction pilot tests In 1996, <br /> GTI conducted a feasibility study, which included pilot level field work to test the <br /> appropriateness of several remedial options The GTI report concluded that a <br />' combination of vapor extraction and groundwater pumping offered the most attractive <br /> option for remediation of the gasoline plume at this site <br />' In 2000, Geo-Phase Environmental Inc constructed a deep (97 feet) monitoring well to <br /> define the vertical extent of the contaminant plume, and also conducted a pilot remedial <br /> test of vapor extraction and air sparge technologies The deep monitoring well produced <br />' groundwater samples that contained non-detectable levels of gasoline range petroleum <br /> hydrocarbons Based on the results of the pilot testing as well as previously completed <br /> work, a Feasibility Study was completed which evaluated the relative merits of four <br /> different remedial methods The Feasibility Study concluded that the remedial method <br /> best suited for this release will consist of simultaneous vapor extraction and air sparging <br /> I <br /> 2937 Veneman Ave, 413240 Geo-Phase Environmental Inc Phone(209)569-0293 <br /> Modesto,CA 95356 Fax(209)569-0295 <br />
