Site Description

The 23-acre Refuse Hideaway Landfill site, located in rural Dane County, Wisconsin, was licensed by the Wisconsin Department of Natural Resources (WDNR) in 1974. The landfill accepted municipal, commercial, and industrial wastes until 1988, when it was closed by order of a state court. The owner of the landfill, under oversight of WDNR, complied with the closing order by installing a clay and soil cap and seeding the cover. Public and private wells, located within four miles of the site, provide water supplies to an estimated 14,600 people in the area. The nearest of these wells is privately owned and located within one-half mile of the site. 

Site Responsibility

This site is being addressed through federal and state actions.

Threats and Contaminants

Soils and onsite and offsite groundwater, including private wells southwest of the site, are contaminated with various volatile organic compounds (VOCs), including perchloroethene, trichloroethene, and vinyl chloride. Individuals who accidentally ingest or come into direct contact with contaminated soil or groundwater could be at risk. 

Cleanup Progress

In 1988, WDNR detected VOC contaminants in three privately owned wells. Treatment systems were installed for two of the wells with the third well taken out of service. Beginning in 1989, WDNR installed a methane gas and leachate collection system and conducted landfill cap repairs. These actions reduced immediate threats that were posed to the safety and health of the nearby population, while further cleanup activities were being planned. 

WDNR conducted an investigation to define the contaminants and recommend alternatives for the final cleanup. In 1995, the selected site cleanup remedy included groundwater extraction and treatment to contain the contaminant plume, operation and maintenance of the existing landfill cap, gas and leachate systems, and a contingent option to allow the installation of additional point-of-entry treatment systems, should additional wells become contaminated. An administrative order on consent (AOC) was signed with the potentially responsible parties (PRPs) in April 1997 for the design of the selected remedy, groundwater pump and treat. The AOC also allowed the PRPs to collect data, showing that natural attenuation of groundwater contamination is occurring at a rate similar to that which could be achieved by using pump and treat.  From this information on September 30, 1998, an explanation of significant difference (ESD) was issued that eliminated the groundwater extraction and treatment component of the selected remedy.  The state of Wisconsin entered into a consent decree on August 31, 2001, to complete the modified design and continue cleanup work. The continuing cleanup work consists of long-term operation and maintenance of the existing landfill cap; gas and leachate systems; monitoring of these systems by gas, leachate, and groundwater sampling; and as a contingency, installation of additional point of entry treatment systems if needed. WDNR is currently performing this work and will continue to do so until cleanup goals have been achieved. In 2010, WDNR purchased, installed, and successfully started up solar energy photo-voltaic equipment, which provides power for site remedy systems.  Another ESD was issued on June 22, 2012 that updated the site cleanup goals for groundwater to the state of Wisconsin's Enforcement Standards.  The first five-year review for the site was completed on September 17, 2007 and the second five-year review was completed on August 29, 2012.  The five-year review determined that the site remedy continues to be protective of human health and the environment.

Community Involvement

WDNR and EPA are available to discuss any problems or concerns brought forth by the community.  As part of weekly Site operations, the contractor performing the work for WDNR regularly observes the Site and surrounding areas and communicates regularly to WDNR regarding any potential problems.  Over the past several years, no problems or concerns with the site have been communicated to WDNR or EPA.
