WILLIAMS MHP is one of 4,942 community water systems in North Carolina in the 500 or fewer people size category, formerly serving 45 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 18 entries between 1986 and 1993, all of which EPA lists as closed. Nothing has been added since 1993.

All 18 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, the Radionuclides and Revised Rad Rule, and the Lead and Copper Rule.
