i <br /> I <br /> REMEDIATION SYSTEM SUMMARY <br /> In Situ Groundwater Extraction and Treatment System VB <br /> System description <br /> A vacuum vaporizer well system,known as UVB (Unterdruck Verdampfer Brunnen), is capable of <br /> extracting groundwater from one well,UVB The UVB treatment system consists of an in situ,400- <br /> millimeter-diameter reduced pressure air stripper and a 5-horsepower blower and includes a <br /> weatherproof cover and moisture knockout drum The moisture knockout drum has a built-in <br /> stripping unit to treat any accumulated water prior to removal Vapors stripped from groundwater in <br /> the UVB air stepper are extracted by the UVB vacuum blower The pressure outlet of the UVB <br /> blower is connected to a Thermtech VAC 25 thermal/catalytic oxidizer, to destroy volatile organic <br /> Icompound vapors in a heated chamber prior to release into the ambient air <br /> System startup date- 6 February 1997 <br /> Active extraction wells. None <br /> Inactive extraction wells/reason: UVB (The system was shut down on 22 September 2000 as <br /> proposed during the 12 September 2000 meeting between San <br /> Joaquin County Public Health Services and ExxonMobil <br /> Refining and Supply Company) <br /> lie Modifications made during reporting period/reasons for modifications <br /> None <br /> Status of system operation during reporting period/reasons for downtime: <br />' The UVB system did not operate <br /> ISystem performance data totals (totals since system startup) <br /> Groundwater extracted: Not applicable <br /> Pounds of TPH removed: 1,998 7 (calculated as TPH-g) <br /> Pounds of benzene removed: 1845 <br /> Pounds of MTBE removed.
