- Madison Metropolitan Sewerage District Lagoons added to EPA's Superfund list
- What occurred
- In April of 1970, 1 of the 2 sludge lagoons belonging to the sewage treatment facilities of south Madison partially collapsed, releasing 85 million gallons of sludge into a nearby ditch. Initially, a management plan suggested reusing the sludge as fertilizer for agricultural land in the area. However, in 1982, it was determined that the sludge had high levels of PCBs, thus leading to the addition of the site to the EPA's Superfund list in 1990. The site achieved the status of "ready for anticipated reuse" in 2010 after the construction of a soil and fabric cover over the lagoons and after waiting long enough for PCB concentrations to adequately decrease. The attached picture shows the installation of a site security fence.
