The Site Characterization Report was approved in 1998. Active and passive soil and groundwater remediation occurred between May 2000 and August 2015.

A Soil Vapor Extraction (SVE)/Air Sparge (AS) system operated between October 2001 and November 2003.  A total of 8,576 pounds of volatile organic compounds (VOCs) was extracted.  From May 2005 until March 2011 seventeen mobile multi-phase extraction events occurred. A total of 1,148 pounds of petroleum hydrocarbons were extracted from the groundwater. Remediation activities for soil also included the excavation of approximately 3,294 cubic yards of contaminated soil.
