Dive Brief:

• The Environmental Protection Agency (EPA) has concluded that the caps at two shuttered landfills at New Jersey’s Cinnaminson Groundwater Contamination Superfund are sufficient for the sites. The Superfund is located in the Cinnaminson and Delran townships.
• The EPA assessed the conditions at the site and found that no further contamination issues exist at this time. The agency monitored groundwater for 26 years before coming to its conclusion.
• The EPA has been overseeing the site's closure, which included capping the two landfills in 1987. At that time, tests showed that groundwater and soil had been tainted with volatile organic compounds and heavy metals. 

Dive Insight:

The site closed in the 1980s, with the EPA taking control of the site when it was added to the Superfund list in 1986. The agency will continue to monitor the site and address any issues that arise. 

Superfund sites are added to an ongoing list of areas monitored by the EPA. Sites are added to the list due to certain landfills' potential to increase health and environmental hazards. The EPA has listed almost 1,700 sites to the National Priority Superfund list since the program's launch in 1983. Since then, approximately 68% of the listed areas have cleanup procedures in place, while 36% have long-term plans for redevelopment and reuse.
