Jones Sanitation is a 57-acre former industrial and septic waste disposal facility in Hyde Park, Dutchess County, New York. It operated from 1956 to 1977 and accepted industrial liquid wastes and sludges, including oils, solvents, metals from plating operations, and other hazardous materials. EPA placed it on the National Priorities List in July 1987.
Thirty-four contaminants of concern were identified across soil, groundwater, sediment, and surface water. These include heavy metals such as arsenic, cadmium, chromium, lead, mercury, nickel, and zinc. Volatile organic compounds include benzene, vinyl chloride, tetrachloroethene, methylene chloride, chloroform, and trichloroethylene. Polychlorinated biphenyls (PCBs) and several polynuclear aromatic hydrocarbons (PAHs), including benzo[a]pyrene, were also found.
EPA selected a cleanup plan in March 1997. The approach involved digging up contaminated soil, consolidating it in a central area, and building an engineered cap over it. Groundwater monitoring was also required. Construction ran from September 2000 through December 2001. Legal restrictions filed with the Dutchess County Clerk in September 2004 prohibit development on the capped area and ban groundwater use beneath it except for monitoring. Groundwater outside the cap cannot be withdrawn without EPA approval.
EPA deleted the site from the National Priorities List in September 2005 after confirming cleanup was complete. Human exposure is under control, and groundwater migration is stabilized with no unacceptable discharge to surface water. A portion of the property now serves as a parking and truck storage area, and wetlands and wooded areas on the site were protected. The site achieved sitewide ready for anticipated reuse status in March 2009. The fourth five-year review, completed in July 2021, confirmed the cleanup continues to protect human health and the environment. The next five-year review is estimated between July and September 2026. Ongoing activities include groundwater monitoring, gas monitoring, and routine cap inspections.
