Site Description

The Dakhue Sanitary Landfill covers 25 acres of an 80-acre property located in Dakota County, six miles north of Cannon Falls, Minnesota.  From 1971 to 1988, the property was used as a privately owned and state-permitted sanitary landfill.  The landfill was used for the disposal of mixed municipal and commercial waste and small amounts of industrial waste.  The area surrounding the landfill consists mainly of single family residences and farms.  Residential drinking water supply wells, municipal water supply wells, and irrigation wells in the surrounding area draw groundwater from a shallow aquifer and from deeper aquifers.  Pine Creek, located a mile south of the site, and the Cannon River, located three miles south of the site, are used for recreation by area residents.  

Site Responsibility

Site cleanup was addressed through federal, state, and potentially responsible party (PRP) actions.  Currently the site is operated and maintained by the Minnesota Pollution Control Agency (MPCA) as part of its Closed Landfill Program.  

Threats and Contaminants

The landfill contains approximately 1.5 million cubic yards of mixed municipal, commercial, and industrial solid wastes.  Groundwater beneath the landfill was contaminated with volatile organic compounds (VOCs), chloroform, and heavy metals, including cadmium and lead. 

Cleanup Progress

The site was listed on the National Priorities List in 1990.  Shortly thereafter, responsible parties completed interim erosion control measures, filled in areas where waste was exposed, and re-directed surface water runoff into catch basins.  Under the supervision of the MPCA, responsible parties also conducted a remedial investigation and feasibility study (RI/FS).

In 1991, the MPCA and EPA signed a cleanup decision for the landfill.  Required actions included fencing and capping of the landfill, installing a passive gas control system and an active leachate collection system, and monitoring of air and groundwater.  In 1992, the Agencies modified the decision to make a change to the cover design.  In 1993, MPCA, with EPA's concurrence, selected a remedy for groundwater which required ongoing monitoring of natural attenuation, and additional actions if that was not sufficient.  Construction for the site was completed in 1994.  In 1995, following an agreement between MPCA's Closed Landfill Program and EPA, the site was deleted from the National Priorities List.

Landfill maintenance and groundwater monitoring are conducted by the MPCA's Closed Landfill Program.  In 2003, the MPCA constructed a major upgrade to add active control of landfill gas.  EPA conducts Five-Year Reviews for the site. The latest review was completed in 2014 and documented that the remedy for the landfill is protective of human health and the environment because the landfill cap is intact, landfill gas is under control, and the groundwater plume is stable and continuing to attenuate.
