NPL Site Narrative for Jackson Steel
Mineola, North Hempstead, New York
Conditions at Proposal (October 22, 1999): The Jackson Steel site is an inactive "roll form metal shapes" manufacturing facility located in Mineola/North Hempstead, Nassau County, New York. It is not known when Jackson Steel began operating; however, they submitted a form/application to the Nassau County Health Department on October 19, 1977. Jackson Steel reportedly ceased operations at the site in April 1991. Degreasers, including tetrachloroethylene (also referred to as perchloroethylene (PCE)), trichloroethylene (TCE), and 1,1,1-trichloroethane (TCA), were used at the site until March 1985. Degreasing sludge was stored in drums on a paved area located southwest of the building. The site property is bordered to the northwest by First Street, to the northeast by an apartment building, to the southeast by a billiard parlor and an electronics store, and to the southwest by a paved parking area, law offices, and a bar/restaurant. The site is located on the edge of a mixed-use area, with commercial and industrial properties located to the south and west and residential properties located to the north and east.
The Nassau County Department of Health conducted numerous inspections of the Jackson Steel site between 1979 and 1996; improper spill control at the waste storage area was noted once, in 1981, during the period when degreasers were used on site. A Limited Phase II Assessment of the Jackson Steel site was performed in December 1991. During this inspection, a third dry well was observed in the building, in the loading dock. Soil samples collected beneath the dry wells indicated the presence of PCE, TCE, 1,1,1-TCA, 1,2-dichloroethylene (DCE), and 1,1-dichloroethane (DCA) at depths up to 17 feet below ground surface. 1,2-DCE is a degradation product of TCE and PCE and 1,1-DCA is a breakdown product of PCE, TCE, and 1,1,1-TCA.
A reconnaissance of the site was conducted in November 1992 as part of an Environmental Site Investigation (ESI). Numerous stained areas and puddles were observed in the building. Drums containing petroleum products were stored in the building and on the paved area. The dry wells were partially filled with liquid and a 275-gallon degreasing tank was observed "in close proximity" to the dry well located in the loading dock. Between December 1992 and February 1993, numerous samples were collected in, around, and below the dry wells and nine ground water samples at the site. The analytical results reportedly indicated the presence of PCE, TCE, 1,1,1-TCA, and 1,2-DCE at depths up to 40 feet below the ground level and PCE, TCE, 1,1,1-TCA, 1,2-DCE, and 1,1-DCA in ground water collected from monitoring wells located downgradient of the dry wells.
The ESI report suggests that a release of PCE, TCE, and 1,1,1-TCA to ground water has occurred from the site. Drinking water within 4 miles of the site is derived from public/municipal supply wells screened in the Upper Glacial, Magothy, and Lloyd Aquifers. The nearest well drawing from the aquifer of concern is located approximately 3,100 feet south and side-gradient to the site. Potable wells within 4 miles of the site, and drawing from the aquifer of concern, serve over 300,000 people.
Status (February 2000): EPA is considering various alternatives for this site.
