Cherokee Road ROM 0118 <br /> Stockton, CA 95205 Global ID#: T0607700156 <br /> The San Joaquin County Environmental-Health Department (EHD) has reviewed <br /> Five-Day High Vacuum Soil Vapor Extraction (HVSVE) Pilot Test Report (Report) <br /> dated March 21, 2011 submitted by your consultant, Advanced GeoEnvironmental <br /> Inc., (AGE). The Report details the five-day high vacuum soil vapor extraction <br /> (SVE) pilot test conducted on-site in February 2011. The EHD had approved this <br /> test by correspondence dated December 14, 2010. <br /> It was concluded in the Report that soil vapor samples collected during the test <br /> contained total petroleum hydrocarbons as gasoline (TPHg) were detected ranging <br /> as high as 26,000 micrograms per liter (ug/1) and that approximately 410 pounds of <br /> gasoline were removed during the test. The radius of influence of.induced vacuum <br /> was as much as 100 feet from the extraction test well, VW-1. AGE recommended <br /> that a remedial action plan (RAP) be prepared proposing HVSVE as the <br /> remediation technology for vadose zone and deeper hydrocarbon-impacted soils. <br /> The EHD concurs. <br /> Please submit a RAP to the EHD (Geotracker) within 60 days. <br /> If you have any questions, plea contact Michael Infurna at (209.)468-3454. <br /> Zichael J.
