Superfund Site Profile
The 40-acre Northern Engraving Corporation (NEC) site is located in Sparta, Wisconsin. An active NEC manufacturing facility on site produces metal name plates, dials and decorative trim for the automotive industry, using anodizing, chemical etching and chromate conversion-coating processes. Past wastewater treatment and disposal practices led to soil, groundwater and surface water contamination. Following cleanup, EPA took the site off the Superfund program’s National Priorities List (NPL) in 1997.
