SEAWOOD ESTATES MUTUAL WATER COMPANY is one of 3,951 community water systems in California in the 500 or fewer people size category, serving 63 people from surface water.
As of August 1, 2026, its federal record holds 13 entries between 1980 and 2014, all of which EPA lists as closed. Nothing has been added since 2014.
Of the 13, 3 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 the Miscellaneous Other Rules, the Surface Water Treatment Rules, and the Radionuclides and Revised Rad Rule.
