To further protect public health, EPA will conduct long-term monitoring of the groundwater, in addition to other protective measures.

The EPA has finalized a cleanup plan to address groundwater contamination in the townships of Cinnaminson and Delran, New Jersey. The final decision addresses contaminants in groundwater at the site by using pump, treat and discharge methods that will capture groundwater contamination that can pose series health risks to citizens.

To further protect public health, EPA says that it will conduct a long-term monitoring of the groundwater, in addition to other protective measures.

“This decision reflects close coordination with the New Jersey Department of Environmental Protection as well as with the Townships of Cinnaminson and Delran to ensure the groundwater contaminants are properly treated and that the environment is secure,” said Acting Regional Administrator Walter Mugdan said in a press release. “This Record of Decision, which is critically important to community members in Cinnaminson and Delran, builds on earlier decisions at the site in which EPA called for the installation of vapor recovery systems at impacted properties and a groundwater pump and treatment system, and ensured the sufficiency of the existing landfill caps at the site.”

Under the finalized cleanup plan, EPA will target highly concentrated portions of the contaminated groundwater near the source areas by using a pump and treat remedy. EPA will also implement institutional controls, such as restricting the use of groundwater from the site, to prevent and reduce human exposure to contaminated groundwater until the cleanup goals are met. Furthermore, EPA will require periodic collection and analysis of groundwater samples to verify that the level and extent of contaminants are declining.
