ROHNERT PARK, CITY OF is one of 376 community water systems in California in the 10,001 to 100,000 people size category, serving 43,821 people from groundwater.

As of August 1, 2026, its federal record holds 200 entries between 2017 and 2021, all of which EPA lists as closed. Nothing has been added since 2021.

All 200 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 volatile organic chemicals, the Total Coliform Rules, and inorganic chemicals.
