Crown Vantage LandfillAlexandria Township, New Jersey
Hunterdon County7th Congressional District

iconSite Location/Size:
   The Crown Vantage Landfill site is an inactive industrial landfill located off Milford-Frenchtown Road (County Route 619) in Alexandria Township, Hunterdon County, New Jersey. The site encompasses approximately 10 acres within the floodplain of the Delaware River.

iconSite History:
   Waste deposition activities at the site began in the late 1930s and continued until the early 1970s. Background information indicates that the site has been inactive since that time. The landfill was used by previous owners for the deposition of wastes generated at a paper mill, including flyash and drums containing press room wastes (varnish, shellac, methyl ethyl ketone (MEK), inks, and dyes).

iconSite Contamination/Contaminants:
   Surface soil, flyash, and sediment samples indicate that site-attributable contaminants have been released to the Delaware River. Surface soil samples contain semi-volatile organic compounds (SVOCs), PCBs, and metals (including barium, chromium, and lead) at elevated concentrations. Flyash samples reveal elevated concentrations of SVOCs, including polycyclic aromatic hydrocarbons (PAHs). Metals detected at elevated concentrations in flyash samples include lead and chromium. PAHs were also detected in soil at concentrations exceeding screening levels.

iconPotential Impacts on Surrounding Community/Environment:
   The Delaware River adjacent to and downstream of the site is used for fishing. Surface soil, sediment, and flyash samples collected in November 2003 document a release of contaminants into the surface water and actual contamination of the Delaware River in areas used for fishing. Potential receptors of contamination within 15 miles downstream include approximately 1.8 miles of wetland frontage, one State-listed threatened species habitat, and two Federally-listed threatened species habitats. In addition, the Lower Delaware River, downstream of Alexandria Township, is a National Wild and Scenic River.

iconResponse Activities (to date):
   EPA completed shoring up specific areas of the landfill in November 2004, after the bank of the landfill was substantially damaged by flood waters associated with summer hurricanes. In addition to shoring up areas where the landfill collapsed, EPA placed warning signs along the perimeter. While the Agency's actions addressed the most severely damaged sections of the landfill, the entire landfill face will need stabilization in order to minimize the potential for further damage. In early April, 2005, the Delaware River, at a gauging station closest to the landfill, peaked 11 feet over flood stage due to a surge of spring rainfall; this was the third highest crest recorded at that location in the past 160 years at that location. On April 5, 2005, EPA observed potential areas of erosion and two subsidences several feet in depth at one part of the landfill after the flooding. Water levels remained high restricting observations; however, the areas stabilized previously by EPA, that were viewable, appear to have held. EPA will continue the process of assessing the flood damage for potential response actions.
