SITE BACKGROUND

The Peninsula Boulevard Groundwater Plume site consists of an area within and around a tetrachloroethylene (PCE or perc) groundwater plume in Hewlett, New York. The groundwater flows toward the northwest, in the direction of the New York American Water Plant 5 Well Field, a source of drinking water. Since April 1991, the Plant 5 well water has been treated by a packed tower aeration system, also known as an air stripper. EPA issued a Record of Decision (ROD) in 2011, selecting groundwater extraction and treatment, as well as limited bioremediation, as the remedy to address the groundwater contamination.  The remedial design (RD) for the site’s groundwater treatment system, as well as the bioremediation, was completed in September 2016.  The designs have not yet been constructed.  EPA completed the remedial investigation to identify the sources of the groundwater contamination in May 2017, and in June 2016, issued a Proposed Plan outlining the preferred remedy for the source areas.
