Superfund Site: NEASE CHEMICAL

Superfund Site Profile


The 44-acre Nease Chemical site is located near Salem in Columbiana County, Ohio. Between 1961 and 1973, Nease Chemical produced various chemical compounds, including household cleaning compounds, fire retardants and pesticides (most notably mirex, a probable human carcinogen). Facility operations contaminated soil and groundwater with hazardous substances. Surface water runoff also carried contamination into the Middle Fork of Little Beaver Creek (MFLBC), which is an important natural resource in the region. Design of the site’s long-term remedy and negotiations for its implementation are underway.
