DAKHUE SANITARY LANDFILL

EPA ID# MND981191570
Last Updated: July, 2012

Site Description

The Dakhue Sanitary Landfill covers 25 acres of an 80 acre site 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 site 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 parties' actions.  Currently the site is operated and maintained by the Minnesota Pollution Control Agency'.  

Threats and Contaminants

Approximately 1.5 million cubic yards of mixed municipal, commercial, and industrial solid wastes are on the site.  Onsite groundwater 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 garbage was exposed, and re-directed surface water runoff into catch basins.  Under the supervision of the Minnesota Pollution Control Agency (MPCA), responsible parties also conducted a remedial investigation and feasibility study (RI/FS).

In 1991, the MPCA and U. S. Environmental Protection Agency (U.S. EPA) signed a cleanup decision for the landfill.  Required actions included fencing and capping the landfill, installing a passive gas control system and an active leachate collection system, and monitoring air and groundwater.  In 1992, the Agency's modified the decision to make a change to the  the cover design.  In 1993, MPCA signed, and EPA concurred with, a remedy decision 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, the site was deleted from the National Priorities List.

Currently the landfill and groundwater monitoring are operated and maintained by the Minnesota Pollution Control Agency under its Closed Landfill Program.  In 2003, the MPCA constructed a major upgrade to add active control of landfill gas.  The latest five-year review for the site was completed in 2009 and documented that the landfill is protective of human health and the environment and all unacceptable risks from groundwater remain controlled.
