Approximately 2,800 cubic yards of material was excavated at the site. The material was treated and reused at the site. Off-site transportation and disposal would have cost an additional $500,000 over the treatment costs.
Cement-based solidification/stabilization (S/S) treatment technology is enabling the U.S. Environmental Protection Agency to clean up the New Bedford Harbor Superfund site while reusing the treated material to build a dewatering facility.
The Retek Process is a well established on-site remediation approach that has been applied to a broad range of contaminated soils, dredge and other media, contaminated with substances classified as "hazardous" by the Environment Agency and US EPA.
It had been the initial intention to excavate and transport the contaminated soil to either a treatment facility or landfill. United Retek’s on-site remediation technology was chosen instead as the processed material can be used as structural fill and paving base for the parking lot, representing additional project savings as compared to trucking in backfill to the site.
