BIG OAK REHAB is one of 428 community water systems in New Jersey in the 500 or fewer people size category, serving 259 people from groundwater.
As of August 1, 2026, its federal record holds 3 entries between 1979 and 2018, all of which EPA lists as closed. Nothing has been added since 2018.
Of the 3, 2 are monitoring and reporting requirements — the category that accounts for about four in five of all violations in EPA's national dataset — rather than findings about the water itself. The record involves inorganic chemicals and the Radionuclides and Revised Rad Rule.
