Results of a ground-water and DNAPL recovery and containment strategy
- DuPont Environmental Remediation Services, Niagara Falls, NY (United States)
Ground-water contamination and dense nonaqueous phase liquids (DNAPL) were discovered at the DuPont Necco Park Landfill in Niagara Falls, New York, shortly after the facility was closed in the late 1970s. The facility received a variety of solid and liquid process wastes, including chlorinated volatile and semivolatile organic compounds. A number of proactive response activities--including the operation of a ground-water recovery system, installation of a grout curtain, and DNAPL recovery--were implemented by DuPont concurrent with site characterization. These efforts minimized off-site contaminant migration and removed most of the recoverable free-phase DNAPL prior to completion of the full site characterization. Site investigations to characterize hydrogeologic controls over occurrence and migration of ground water and DNAPL revealed with distinct water-bearing zones beneath the site. A DNAPL recovery program, using gas-driven pump assemblies, was initiated in early 1989 at a small group of wells where DNAPL was frequently observed. The volume of recovered DNAPL declined over the next four years from a peak of 397 gallons per month in 1989 to little or no recovery in recent months.
