    Stage of Clean-up: Remedial Assessment Not Begun

    The Peninsula Boulevard Ground Water Plume site (CERCLIS No. NYN000204407) is the location of a ground water plume with no identified source(s) of contamination. The area under which the ground water plume lies is predominantly residential. The plume was discovered when New York State Department of Environmental Conservation (NYSDEC) conducted a Remedial Investigation (RI) of a dry-cleaning business in Hewlett, New York. The investigation results indicated that almost 6 parts per million (ppm) of tetrachloroethylene (PCE) are present in shallow ground water; however, the highest concentrations and majority of plume area are not located directly beneath the subject dry-cleaning facility. Therefore, NYSDEC concluded that there is not enough evidence to identify the subject facility as a source of contamination. There are numerous other current and former dry-cleaning facilities in Hewlett. The NYSDEC RI indicated that ground water flows from the main plume area to the northwest, in the direction of the Long Island Water Corporation (LIWC) Plant 5 Well Field. This cluster of 43 active wells (and numerous inactive wells) is located just northwest of the plume delineated by the RI. The active wells are all screened in the Jameco aquifer (i.e., aquifer of concern, as discussed below) at depths of approximately 150 feet, and contribute to the LIWC system through a common suction unit that prevents access to individual wells.  More...
