Site Description

The Schmalz Dump site, located in the Town of Harrison, Calumet County, Wisconsin, covers three-quarters acre near the northern shore of Lake Winnebago.  The ten and one-half acre site includes the capped seven-acre dump, three acres of adjacent property, and a half-acre wetland.  Unauthorized dumping occurred at the site from 1968 to 1979. In 1972 through 1973, fly ash and bottom ash from a utility company were disposed of on the site. In 1978 through 1979, building demolition debris, contaminated with polychlorinated biphenyls (PCBs), was disposed of on the site.  The property adjacent to the dump does not contain waste material from the dump and is not covered by the impermeable cap. The Site is bound to north and west by what were historically wetlands that have been filled for commercial development.  Sixty residences and businesses are located within 1,000 feet of the site.  A wetland borders the east side of the Site. A railroad right-of-way is on the southern border. South of the railroad tracks is a residential area called Waverly Beach.  In 1984, all residences in the Waverly Beach area were connected to the City of Menasha water system. A number of residents still have private wells, but use them only for watering yards and other outdoor purposes.

Site Responsibility

Remedial actions were implemented using federal funds.  PRPs have reimbursed some federal costs.   The site is being addressed through state actions.

Threats and Contaminants

Groundwater is contaminated by lead and chromium; soil, sediments, and surface water were contaminated with heavy metals and PCBs. A health threat would exist if the site or site groundwater was developed for residential usage in the future.

Cleanup Progress

In 1985, the United States Environmental Protection Agency (EPA) constructed a fence around the site. In 1988, EPA excavated and removed 3,500 cubic yards of PCB-contaminated soil and sediments. From 1984 to 1987, U.S. EPA conducted a remedial investigation/feasibility study at the site. In 1989 and 1993, private parties entered consent decrees with EPA to reimburse past costs.

In 1994 through 1995, EPA constructed the final remedial action, which primarily consisted of installation of a low-permeability soil cover over the site. The State of Wisconsin continues to conduct the long-term operation and maintenance of the Site. 

The first Five year Review was signed on September 24, 1993.  The remedy was protective of the public health and the environment.

A second Five Year Review was signed in September 1998 and determined that the remedy remained protective of human health and the environment.

EPA and the Wisconsin Department of Natural Resources (WDNR) completed a third five-year review in September 2003.  The review determined that the remedy remained protective of human health and the environment

A fourth Five Year Review was completed by EPA on August 22, 2008.  The remedy was found to be funtioning as intended.  Institutional Controls were evaluated to determine their effectiveness for the long-term stewardship of the remedy.  WDNR will prepare an IC Plan to ensure that effective ICs are implemented and enforced. 

WDNR is conducting annual groundwater sampling at the site to confirm that the groundwater contaminants remain below the Wisconsin drinking water standards.

On June 9, 2011 the Sitewide Ready-for-Anticipated Use (SWRAU) was signed. 

The fifth Five Year Review was signed on August 12, 2013.  The remedy remains protective of human health and the environment because they eliminate the principal threat posed by the Site by preventing direct contact with contaminated materials, removal and capping of contaminated soils, and groundwater monitoring.  Long term protectiveness of the remedies require compliance with institutional controls.  Although ICs are in place, an IC plan will be prepared by the State to include the steps necessary to ensure that the ICs are maintained and effective.
