Dover Municipal Well 4

Dover, New Jersey	

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
construction activities at the site.
