Sixteen Stormceptors® are Integral in Superfund Clean-up
Cleaning up land contaminated by industrial wastes is a lengthy and costly process. The Superfund program addresses abandoned hazardous waste sites and in cleaning-up the contaminated sites, makes them available for reuse. A completed project in Stratford, Connecticut illustrates the success of the federal Superfund project.
Hazardous pollutants from the manufacture of brake pads, clutch components, asbestos gaskets and other automotive parts left a 33-acre industrial site contaminated. The facility was closed in 1989, with its presence reminding the area residents of the hazards associated with industrial facilities.
Ultimately, the location landed on the federal government’s Superfund list. By becoming a Superfund project, the facility was eligible for federal funds as part of the remediation project.
The remediation plan called for recontouring the site and topping the contaminated soil with an impermeable liner cap to eliminate downward migration of contaminants into the groundwater as a result of surface water infiltration.
"The ability to control future sources of pollution from the site was an important issue with regulatory agencies," said Mike Shannon, remediation manager with Foster Wheeler Environmental Corporation (Livingston, New Jersey), the prime contractor for the project.
As part of the storm water pollution plan, sixteen Stormceptor® Systems were installed as part of the drainage system. "With the planned redevelopment of the site as a shopping center, the ability to remove oil, grease and sediment from the surface runoff was a must," added Shannon.
Where portions of the Stormceptor® penetrated the liner, the liner system is "booted" around the unit to ensure a watertight seal. The portions of the Stormceptor® below the liner which would possibly come into contact with groundwater or waste were treated with an epoxy coating.
Stormwater flows into the Stormceptor® and is diverted by a U-shaped weir, through a pipe, and into the separation/holding chamber. Right angle outlets direct flow around the chamber to the submerged outlet pipe. Fine and coarse sediments settle to the bottom of the tank, while petroleum products and floatables rise and become trapped underneath the weir.
The Stormceptor® units were manufactured by Rinker New England Pipe, in Wauregan Connecticut. The Rinker Materials Corporation Wauregan office provided technical and installation support for the project.
