Clean soil was brought to the site for backfilling, followed by grading and grass-seeding. Installation of a pilot groundwater treatment facility was accomplished in 1989. This was followed by a series of field sampling and hydrogeologic studies which lasted until the middle of 1993. The results were used to design the final system, which was completed in September 1994. Groundwater cleanup is currently in progress.
Contaminated water is extracted by wells and cleaned on-site using activated carbon filters.
Finally, clean water is pumped back into the ground through a set of on-site disposal wells. Approximately 33,000 gallons of water are treated per year. This project is expected to terminate in the year 2002. EPA and the State are collaborating in the cleanup efforts which are funded by the potentially responsible parties.
