SITE BACKGROUND

The Nepera Chemical Company site is located in Hamptonburgh, New York. The site is a 29-acre former industrial waste disposal facility. Between 1953 and 1967, lagoons at the site received about 50,000 gallons of wastewater per day from the Nepera chemical plant in Harriman, New York. Nepera made a variety of pharmaceutical and industrial chemicals. State inspectors detected leaks from the lagoons in 1958 and 1960, and operations ended in December 1967. The company’s operations contaminated soils and groundwater with hazardous chemicals. After immediate actions to protect human health and the environment, the site’s long-term cleanup is ongoing.
