The Janesville Disposal Facility (JDF or 'the site') is located ona 65-acre parcel of land located in northwestern Janesville, Wisconsin. The facility contains four different areas: the Ash Beds (a National Priorities List or NPL Site), the Old Dump, the Old Landfill (another NPL Site) and the New Landfill. After reviewing groundwater monitoring data collected over several years, U.S. EPA has determined that natural attenuation has significantly reduced contaminant levels in the groundwater. Based on improvements in the levels of groundwater contamination downgradient of the site, U.S. EPA and WDNR have determined (1) that groundwater extraction and treatment are not necessary to achieve regulatory requirements and to protect public health and the environment, and (2) that these goals can be achieved by natural attenuation of groundwater contaminants. Contaminant concentrations in the groundwater will continue to be monitored and U.S. EPA will periodically review monitoring data to assess whether natural attenuation is reducing contaminant levels in a satisfactory manner.
