nepera chemical co., inc.

COUNTY RT 4

The site is a 29.3-acre former industrial waste disposal facility located in the Town of Hamptonburgh, near the Village of Maybrook, in Orange County. It is in a rural, residential and agricultural area near the confluence of two streams, with wetlands nearby. The former wastewater lagoon area, containing six backfilled lagoons, occupies an area of about five acres. Currently, much of the site is wooded and the former lagoon area is fenced and covered with grasses. Between 1953 and 1967, the lagoons were used to dispose of approximately 50,000 gallons a day of wastewater from the Nepera chemical plant in Harriman, New York. The plant produced a variety of pharmaceutical and industrial chemicals, including pyridine-based compounds. State inspectors detected leaks from the lagoons in 1958 and 1960. Because of the State's continuing concern about the proper containment of the waste and the threat to a local well field, operations were discontinued in December 1967. By 1974, all of the lagoons had been backfilled with soil. Approximately 6,500 people live within a 3-mile radius of the site. The closest residences are located approximately 250 feet to the west, and 175 feet and 450 feet to the northeast. These residences rely on private supply wells for drinking water. Monitoring of these residential wells is conducted on an ongoing basis for all site-related contaminants. Furthermore, three (3) public water supply wells owned by the Village of Maybrook, which lie approximately 800 feet north of the site, are monitored for site-related contaminants on a quarterly basis. Site Responsibility: This site is being addressed through federal, state, and potentially responsible party actions
