Site Description

The Dover Municipal Well No. 4 site is located in the Town of Dover, New Jersey. Dover Municipal Well No. 4 is located approximately 1.5 miles east of three potable water production wells that serve a community of approximately 22,000 people. The Dover Water Commission owns and operates this municipal well field. Dover Municipal Well No. 4 was one Dover's primary drinking water supply wells. In 1980, it was taken out of service because ground water contaminated with halogenated organic solvents was discovered. Since that time, standby well No. 3 has been used in place of well No. 4 as a potable water production well.

Current Site Status and Cleanup Actions to Date

  • In 1992, EPA issued a Record of Decision (ROD) that addressed the ground water portion of the site with the installation of a pump and treatment system. EPA amended the ROD, however, by eliminating the treatment system because the contamination in the ground water has decreased significantly through natural attenuation since 1992. EPA currently believes that once the contamination source has been removed, the contaminants in the ground water will reach acceptable levels in nearly the same time as they would with active treatment.
  • In 2005, EPA issued a Record of Decision (ROD) selecting a remedy that includes demolishing a dry cleaner building, excavating contaminated soil, and chemically treating residual source material.
  • In 2007, EPA started actions to implement the 2005 ROD.

Current Funding Status

  • In Fiscal Year 2007, EPA obligated approximately $3 million for cleanup activities at this site.
