RIDGEWOOD WATER SYSTEM is one of 3,951 community water systems in California in the 500 or fewer people size category, serving 265 people from surface water.

As of August 1, 2026, its federal record holds 6 entries between 1980 and 2013, all of which EPA lists as closed. Nothing has been added since 2013.

Of the 6, 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 the Radionuclides and Revised Rad Rule, inorganic chemicals, and the Miscellaneous Other Rules.

It lists the contaminants detected in the system’s water during the year, where the water comes from, and how the results compare with federal limits. EPA’s revised CCR rule takes effect January 1, 2027, and the first reports in the new format are due July 1, 2027.
