Posted

A work plan to clean up contaminated soil in East Rockaway was scheduled to start this week, according to the New York State Department of Environmental Conservation.

Under New York State’s Brownfield Cleanup program, the work to address the contamination will be done at the Minute Man Cleaners site at 89 Ocean Ave. Ben Ley Enterprises, Inc. will perform the cleanup with oversight provided by the New York State Department of Environmental Conservation. The goal of the cleanup action, said the DEC, is for the site is to achieve levels that protect public health and the environment.

The cleanup action for the site includes:

• In-situ chemical oxidation of residual contaminated soil and groundwater. ISCO is a technology used to treat volatile organic compounds in the soil and groundwater. The process injects a chemical oxidant into the subsurface. The chemical oxidant will be applied onsite through multiple injection points.

• Performance groundwater sampling after the subsurface injections is completed to evaluate the effectiveness of the injections.

• Continued operation of the soil vapor extraction system

• Institutional controls in the form of an environmental easement will require periodic certification of institutional and engineering controls allowing for commercial and industrial use of the controlled property, restricting groundwater usage at the site, evaluation of the potential for on-site soil vapor intrusion if the use of PCE on-site is discontinued; and a provision for the consideration of sampling upon request from the property owner in offsite locations where access was previously refused in the past.
