More than 18 million gallons (bulk and containerized liquids and solids) were disposed of at the site, which was licensed by the State to accept industrial wastes. Substances found on-site include pesticides, solvents, alcohols, waste oils, paints, acids, caustics, and metal sludges. In 1976, the State found that on-site monitoring wells were contaminated. Subsequently, the State initiated an administrative enforcement action against the owner. An EPA inspection in 1979 also detected contamination of ground water and surface water.
