The NW Mauthe site is a former electroplating facility located in Appleton, Wisconsin. The property is located in an area of mixed residential, commercial, and light industrial. The site is bordered by Melvin Street on the north, a parking lot owned by Miller Electric and Manufacturing Company on the west, and the Wisconsin Central Transportation Corporation railroad. The site is currently inactive.

The NW Mauthe site operated from 1960 to 1987. Hard chromium plating took place in the on-site building until 1976. In 1976, chromium plating operations ceased at the site. From 1978 until 1987 the site was used for electroplating of zinc, cadmium, copper, and possibly silver. During the operations, hydrogen gas and chromic acid mists generated from the chromium plating process were blown outside of the building by fans, while splashes, drips, and spills were directed to a shallow floor trench and channeled into the sanitary sewer system. Also, cracks and pits were formed around the plating bath area which allowed infiltration of solvents into ground water and soil.

In March 1982, ponded yellow-green water was reported to the Wisconsin Department of Natural Resources (WDNR). In May 1982, over 30,000 gallons of water were pumped and treated from puddles. In late 1982, WDNR installed ground-water collection systems and took soil borings from the site. In October 1984, a federal Superfund Field Investigation Team inspected the site. In September 1988, the WDNR signed a Cooperative Agreement with the USEPA to conduct a fund financed, RI/FS. In 1987, contractors of US Sprint received reports of workers developing rashes and irritations caused by contact with water and soil while digging in trenches by the railroad tracks adjacent to the site. In 1991, the US EPA installed a fence around the NW Mauthe site, excavated the soils and placed highly contaminated soils into containers. Miscellaneous debris was decontaminated and disposed of, or placed in containers. Under contract with WDNR, CH2M Hill conducted a RI/FS at the site in November 1991. A final RI report and the FS report was approved in late 1993.

The ROD addresses the contaminated soils and surface water at the site which pose a threat to human health and the environment because of risks from possible ingestion or dermal contact.
Remedy:  The selected remedial action for this site includes: demolishing and removing of buildings on the property; removing and disposing the containerized waste currently at the site; excavating soils with elevated concentrations of chromium; treating soils offsite; backfilling the area with clean soil; capping the site with clay soil; installing ground water collection trenches and constructing and operating a ground water treatment facility; installing foundation drain systems and repairing homes; implementing institutional controls; and monitoring.
