ripon city landfill

S OF COUNTY HWY FF

The 7.3-acre Ripon City Landfill (RCL) site is located northwest of the city limits of Ripon, Wisconsin. The site is in a rural area surrounded by woods, a gravel pit, a park, and cropland. Several private homes are located within one-half mile. The RCL site was a former gravel pit that was owned by a private party who leased the land to the Speed Queen Corporation in 1967 for the purpose of landfilling. The City of Ripon began leasing the property in 1968 for the disposal of wastes, and in 1969, it was issued a license to operate the landfill. Later, the Town of Ripon joined with the City of Ripon in operating the landfill. The landfill was operated until 1983 and accepted municipal, commercial, and industrial solid wastes for disposal. In 1984, a residential well located 500 feet south of the site was found to be contaminated with substances from the landfill. The well was abandoned. In 1985, the landfill area was capped with clay, vegetation was established, and a gas venting system was placed along the western edge of the landfill. In 1992, a group of potentially responsible parties (PRPs) signed an agreement with the Wisconsin Department of Natural Resources (WDNR) to complete a full remedial investigation (RI) and feasibility study (FS) at the site and to implement a source control remedy. According to the 2010 census, the City of Ripon had an estimated population of about 7,733 people. Ripon obtains its drinking water from an area groundwater aquifer. One of the city's municipal wells is located 3,700 feet southeast of the landfill. Site Responsibility The RCL site is being addressed through federal, state, and potentially responsible party (PRP) actions.
