(New York, N.Y. - April 24, 2015) The E.P.A. is proposing to modify an interim cleanup project originally issued in 2007 to address a portion of the contaminated groundwater at the Fulton Avenue Superfund location in the Towns of North Hempstead and Hempstead, New York. The groundwater is contaminated with volatile organic compounds (VOCs), including tetrachloroethylene (PCE), that resulted in part from previous dry cleaning operations conducted by a fabric-cutting mill at 150 Fulton Avenue in Garden City Park, New York. The modified project suggested by E.P.A. calls for continuing to operate existing treatment systems for Village of Garden City drinking water supply wells 13 and 14, but eliminates projects for a separate groundwater treatment system for the groundwater near 150 Fulton Avenue. This separate system is not needed, at this time, in part because contamination levels in this area of groundwater have been declining since E.P.A. issued its 2007 cleanup decision. The E.P.A. is taking public comments in this suggestion until May 26, 2015 and will hold a public meeting on Tuesday, May 12, 2015 at 7:00 PM at the Garden City Village Hall, Garden City, New York 11531.
"Long Island relies on groundwater as its major source of drinking water, so it is essential that groundwater resources be protected from toxic contamination," said E.P.A. Regional Administrator Judith Enck.
VOCs can cause cancer and other health impacts. The extent and nature of potential health effects depend on many factors, including the contaminant levels and the length of exposure to the pollution.
Public water supply wells impacted by the contamination have treatment systems and are monitored regularly to ensure that the water quality meets federal and state drinking water standards.
The Fulton Avenue location also includes trichloroethylene (TCE) contamination in groundwater that is being addressed as part of a 2nd phase of work. The E.P.A. is performing an investigation to evaluate the problem and develop a suggested project for the 2nd phase.
From approximately 1965 to 1974, the fabric-cutting mill at 150 Fulton Avenue was operated by several businesses, including a division of Genesco Incorporated Volatile organic compounds from dry cleaning operations at the mill, primarily PCE, were disposed of in a well and seeped into the groundwater beneath the 150 Fulton Avenue property, which has been owned by Gordon Atlantic Corporation since 1963. With the support of New York State, the location was added to the Superfund list in 1998, with New York State taking the lead.
From 1998 to 2004, Genesco Incorporated took certain actions under state oversight to address some of the contamination at the site. The company installed a system to extract VOC vapors from the soil using a type of vacuum.
A technology called air sparging was also used to reduce the contamination in the groundwater underneath 150 Fulton Avenue until contaminant concentrations met New York State requirements. Air sparging is the process of injecting air directly into the contaminated groundwater to reduce VOCs. In addition, a ventilation system was installed to protect occupants of the building at 150 Fulton Avenue from chemical vapors that may enter from under the building there.
In 2007, the E.P.A. issued a cleanup project requiring the construction of a groundwater pump and treatment system nearby in the Village of Garden City, New York, and the treatment of portions of the groundwater containing higher-level PCE contamination at or in the vicinity of the Fulton Property.
After E.P.A. issued its 2007 cleanup decision, sampling results showed that the levels of PCE contamination in the groundwater beneath a portion of the location are declining, and the E.P.A. has therefore determined that the separate groundwater treatment system is not necessary as part of this interim cleanup plan. The E.P.A. will continue to investigate other areas for possible contamination sources that may need to be addressed.
Periodic sampling shows that the existing treatment system for 2 of the Village of Garden City's wells (Nos. 13 and 14) continues to protect the public from exposure to site-related VOCs, including PCE. The pumping of these wells is helping to limit the amount and movement of the contamination in the groundwater near wells 13 and 14.
Currently, the groundwater entering wells 13 and 14 is pumped to the surface and treated using an air stripper, which forces air through polluted groundwater to remove harmful chemicals. This system will continue to be operated and maintained until a final remedial approach for the location is implemented.
The suggested modification of the cleanup project includes other elements, such as an evaluation of chemical vapors that may enter nearby buildings, and also relies upon an existing Nassau Co. law that restricts the installation of private drinking water wells.
The modified remedy will also include sampling and analysis of a monitoring well network and of wells 13 and 14 to ensure protection of public health.
The Superfund plan operates on the principle that polluters should pay for the cleanups, rather than passing the costs to taxpayers. The E.P.A. searches for parties legally responsible for the contamination at sites that are placed on the Superfund list and it looks for to hold those parties accountable for the costs of investigations and cleanups. The E.P.A. expects to modify an existing settlement with Genesco, Incorporated to undertake the cleanup with E.P.A. oversight. The estimated cost of the cleanup is approximately $4 million.
