Superlon Plastics

SITE DESCRIPTION

From 1925 to 1951, the property was used to produce and warehouse lead-arsenate pesticides.  In 1951, the site was sold and operated as a lumber company and wood treatment facility until 1972.  Superlon Plastics purchased the site in 1972 to manufacture plastic piping.  The company is still in operation.  Site investigations led to the discovery of several contaminants above state standards in soil, groundwater and standing water.  Contaminants include arsenic, cadmium, lead, mercury, gasoline and oil range hydrocarbons, pentachlorophenol, tetrachloroethylene, trichloroethylene, cis-1,2-dichloroethylene, vinyl chloride, and chloromethane.
