Chico Urban Area Nitrate Compliance Plan

Visit our mapping tool to find out if your property is in a nitrate project area.

The “Chico Urban Area Nitrate Compliance Plan (Plan)” has been prepared in response to the contamination of groundwater in the Chico Urban Area by nitrate, a form of nitrogen. The discharge from individual septic systems has been cited by the Central Valley Regional Water Quality Control Board (Regional Board) as the primary source of groundwater nitrate contamination that exceeds drinking water standards set by the U.S. Environmental Protection Agency and the State Water Resources Control Board (State Board). Nitrate levels that exceed the standard have been established as a threat to the public health and is subject to regulation.
