1 MTBE Site Closure <br /> Remediation Case History <br /> 1 Isleton, California <br /> ART In-Well Technology <br /> The ART In-Well Technology was implemented at the site of a tanker spill in Isleton, California <br /> (northern) As a result of the spill, the site was impacted by gasoline, diesel and MTBE, which <br /> posed an immediate threat to drinking water wells and an adjacent waterway Responsible parties <br /> identified the ART Technology as the most aggressive and cost efficient remedy to clean up the <br /> impacted areas and mitigate contaminant migration Within months,the ART technology reduced <br /> MTBE contamination levels to below the California primary cleanup standards of 13 <br />' microgram per liter (pg1l) The following table summarizes MTBE concentration reduction over <br /> time at monitoring well MW-2 in the source area where the ART wells were installed <br />' ART Technology Remediation Results <br /> Month/Year 9102 12/02 3103 4103 6103 7103 8103 10103 2/04 <br /> 1 MTBE (µgi1) 42,000 4,800 150 780 32 26 91 57 28 <br /> Note system was shut down m August 2003 <br /> The ART system was shut down in August 2003 Site sampling continued, as requested by <br /> the regulatory agency, to determine if contamination rebound would occur Analytical <br /> testing confirmed that MTBE concentrations did not rebound; instead, concentrations <br /> continued to decrease. The site has been closed, wells pulled and California State closure <br /> ' letter received. <br /> The ART Technology combines in-srtu air stripping, air sparging, soil vapor extraction, Dynamic <br /> Subsurface CirculationTm and enhanced bioremediationloxidabon in an innovative wellhead <br /> system The ART technology has consistently provided enhanced remediation at chlorinated <br /> solvent and hydrocarbon sites - thus avoiding long-term remediation costs. The ART <br /> technology has demonstrated its MTBE remediation ability at this and other sites where <br /> ' other technologies had failed to perform. <br /> For additional information, please contact: <br /> Marco M.
