Site Description

The Freeway Sanitary Landfill site covers approximately 140 acres in Burnsville, Minnesota.  In 1971, the Minnesota Pollution Control Agency (MPCA) licensed the landfill to accept 1,962-acre feet of household, commercial, demolition, and non-hazardous industrial wastes. The state permit prohibited the disposal of liquids and hazardous wastes; however, heavy metals, acids, and bases were accepted by the landfill from local industries. The landfill also accepted 200 cubic yards of battery casings and 448 tons of aluminum sweat furnace slag.  Overall, the landfill contains nearly 5 million cubic yards of waste.  Currently, the waste is covered by a low permeability soil cover.

The groundwater beneath the Freeway Landfill flows into the nearby Kraemer Quarry due to long-term dewatering of the quarry for mining purposes. When this pumping ceases, the ground water flow will change substantially and there is a concern that contaminated ground water could flow into the Minnesota River, which is located aproximately 400 feet from the landfill. The City of Burnsville municipal water supply wells are located about 4,000 feet to the south of the landfill.

Site Responsibility

Currently this site is being addressed through State (MPCA) RCRA post-closure care permit actions.  The site is also a qualified facility eligible to be managed by the MPCA's Closed Landfill Program, but, as of early 2015, a binding Landfill Cleanup Agreement has not been signed.  

Threats and Contaminants

Groundwater contains contaminants which exceed drinking water standards including VOCs, such as tetrachloroethylene (PCE) and vinyl chloride, and metals, such as manganese and thallium.  Other contaminants exceed surface water criteria.  Exposure to contaminated ground water is possible if the pollutants migrate to the Burnsville municipal well field or discharge into the Minnesota River where wildlife could be harmed.   Landfill gases may also be a threat at the site. Currently no gas venting system is in place at the landfill. 

Cleanup Progress

In 2010, MPCA's Closed Landfill Program issued Areas of Concern for landfill gases and ground water at the site.  Based on the large mass of waste present, the lack of a landfill gas venting system, the lack of landfill gas data, and the potential for gas to migrate under seasonal low permeability (frozen) conditions, the MPCA has established a methane gas Area of Concern which extends 300 feet beyond the waste footprint.  Based on groundwater flow conditions at the site, the MPCA has also established a groundwater Area of Concern which extends out from the waste footprint.  Additional measures are needed to address both the landfill and the groundwater to assure long-term protection of human health and the environment.  Currently, pumping related to the nearby quarry operation is controlling human exposure to groundwater.  When this pumping ceases, additional measures will be needed to assure that human exposure to groundwater remains controlled and the nearby river environment is protected.  Discussions between the landfill owner and MPCA are ongoing.
