SOUTH AMBOY W DEPT is one of 97 community water systems in New Jersey in the 3,301 to 10,000 people size category, formerly serving 7,800 people from groundwater.
EPA's federal records list this system as inactive in 2000; the record below is historical.
As of August 1, 2026, its federal record holds 4 entries in 1979, all of which EPA lists as closed. Nothing has been added since 1979.
All 4 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.
