MAMMOTH POOL MOBILE HOME PARK is one of 3,951 community water systems in California in the 500 or fewer people size category, serving 30 people from groundwater.

As of August 1, 2026, its federal record holds 12 entries between 1980 and 2014, all of which EPA lists as closed. Nothing has been added since 2014.

Of the 12, 8 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, the Miscellaneous Other Rules, and the Total Coliform Rules.

What is a Consumer Confidence Report?

A Consumer Confidence Report (CCR) is the annual drinking water quality report that community water systems must provide to the people they serve. 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.
