Public health assessment for Circuitron Corporation, Farmingdale, Nassau County, New York, Region 2. CERCLIS No. NYD981184229. Final report

The Circuitron Corporation site, which is on the National Priorities List, is situated near the Nassau County-Suffolk County border in East Farmingdale, Suffolk County, New York. Subsurface soils at the site are contaminated with metals and volatile organic compounds, primarily copper and 1,1,1-trichloroethane, respectively. Groundwater from the shallow aquifer under the site is significantly contaminated with 1,1,1-trichloroethane at levels exceeding the New York State Department of Health standard for public water supplies and the respective maximum contaminant level set by the United States Environmental Protection Agency. Currently, groundwater in the shallow aquifer is not used as a source of drinking water or for other domestic purposes. The potential for impacts to indoor air quality at nearby businesses warrants the need for further investigation. Other exposure pathways of concern include inhalation, ingestion, and direct contact with on-site soil/sediment/fugitive dusts only during anticipated remedial activities which involve excavation of on-site soils
