Project Name: Carneys Point Township, A. Clemente Asphalt Plant Property

Location of Work: Carneys Point Township, Salem County, New Jersey

Work Scope: Excel Environmental Resources, Inc. (Excel) has been retained by Carneys Point Township to provide overall management and technical consulting to evaluate a large former industrial property and landfill in preparation for redevelopment of this Brownfields property. On behalf of Carneys Point Township, Excel applied for and received a grant for nearly half a million dollars through the New Jersey Department of Environmental Protection (NJDEP) Hazardous Discharge and Site Remediation Fund (HDSRF) to conduct Preliminary Assessment (PA) and Site Investigation (SI) activities at the property in support of the municipality's overall redevelopment plans. The objective of the PA was to satisfy due diligence requirements including the identification of potential environmental areas of concern (AOCs) in accordance with N.J.A.C. 7:26E-3.1, NJDEP Technical Requirements for Site Remediation. Upon completion of the PA Excel identified more than 20 AOCs and subsequently prepared a SI Workplan for NJDEP approval to proceed with characterization of soil and/or groundwater quality. Excel has utilized HDSRF funds efficiently as necessary to characterize soil, surface water, and groundwater conditions at the property. Key aspects of the project include the following:

• Review of aerial photographs and Sanborn™ Fire Insurance Maps to determine historic land use of the property



• Review of local, State and Federal databases to obtain information regarding regulatory information on the properties



• Performance of detailed site inspections to identify potential AOCs for future characterization



• A geophysical survey was conducted to determine the presence of underground storage tanks (USTs), buried drums, and other subsurface metallic objects and debris



• Use of marine magnetometer, side scan sonar, and underwater video equipment to survey two large lakes located on the property and located any submerged drums or other potential environmental concerns



• A wetlands survey was conducted to delineate wetlands boundaries, in preparation for the SI phase of the work



• Based on the data that indicate that historic dumping occurred in a landfill area located on the property, the SI will include characterization of the contents of the landfill and evaluation of engineering alternatives for remediation and/or closure the landfill, as necessary and appropriate based on the findings



• Excel is currently in the process of implementing the SI to characterize the AOCs through sampling of soil, surface water, and groundwater to efficiently characterize the environmental conditions and to gather the data needed to develop conclusions and recommendations to complete characterization and/or to address soil and/or groundwater contamination, as applicable based on the SI results and future development plans for the property.
