SVE Pilot Test at Custer’s Last Camp LUST Site
Using previous experience on similar sites Avanti designed an innovative SVE pilot test system that incorporated a two-tiered vertical screen interval and horizontal layout based on the hydro-geologic conditions at the site. The system performed as expected during the pilot test. This enabled Avanti to use the pilot system in the full scale design which saved the government time and money in implementing and operating the full-scale system. This system has operated very efficiently with free-product levels of hydrocarbons being reduced to ppb levels after 1.5 years of operation.
