The Waterbodies project unit includes Hilliards Creek and its floodplain from West Clementon Road in Gibbsboro to the inlet of Kirkwood Lake in Voorhees, as well as Silver Lake, Bridgewood Lake and Kirkwood Lake.
Over the course of the 125-year industrial history of the former manufacturing plant, certain metals, primarily lead and arsenic, were transported downstream resulting in contamination within the floodplain and lakes.
On April 1, 2021, EPA released a Proposed Remedial Action Plan for the Waterbodies Unit. The proposed plan was based upon a comprehensive Feasibility Study, prepared by Sherwin-Williams, which evaluated the remediation alternatives for Hilliards Creek and its floodplain, as well as Silver Lake, Bridgewood Lake and Kirkwood Lake located in Gibbsboro and Voorhees, New Jersey. The public comment period is complete and EPA is expected to issue a Record of Decision by the end of 2021.
