The long-term remedy at the site included leachate and groundwater collection and treatment, landfill gas venting, monitoring of the effectiveness of the cleanup, and deed restrictions and institutional controls. Construction finished in 2005. However, in 2006, cleanup results did not meet required performance standards.

South Macomb Disposal Authority Landfills 9 And 9a is a federal Superfund site in Michigan. The Superfund program, created by Congress in 1980, addresses sites where hazardous substances have been released or threaten release into the environment. EPA scores potential sites using the Hazard Ranking System; those that score high enough are placed on the National Priorities List.
Current status: Construction complete. Physical construction of the cleanup remedy is complete, though long-term monitoring and institutional controls typically continue for years or decades. Groundwater treatment systems, for example, often run long after surface cleanup finishes.
EPA has identified 10 contaminants of concern at this site, including 1,1-dichloroethane, 1,2-dichloroethene (cis and trans mixture), 1,4-dichlorobenzene. Contamination has been detected in groundwater.
If you live near this site and have health concerns, your state health department can provide site-specific guidance. EPA maintains a community involvement program for most NPL sites, and site documents — including the Record of Decision, five-year reviews, and public health assessments — are typically available through EPA's Superfund site profile.
