ESI signed a performance-based contract to bring chlorinated solvent contaminated soil and groundwater at a dry cleaner site to specified cleanup levels within one year of system operation.

If EPA specified cleanup levels were not met then ESI would have been subject to forfeiture of a performance bond of over $300,000. The EPA suspected this site, along with several others, was contaminating the municipal drinking water supply of Columbus, NE.

This project was conducted as a subcontractor to IT Corporation under the EPA Region 7's Rapid Response Services (ERRS) Contract.

Under this fast track project, ESI constructed a partial system that included a treatment building, an assortment of horizontal and vertical SVE wells, and shallow and deep AS wells; conducted a pilot test; and completed final remediation system design within four months.

Site work was conducted without any accidents and with minimal disruption to dry cleaner operations. Closure criteria were achieved in all soil and groundwater compliance locations within one year.
