Water Quality Report

Since 1990, California public water agencies have been providing an annual Water Quality Report to their customers. Each year ETWD mails out a report in June and covers drinking water testing and reporting for the prior year. The U.S. Environmental Protection Agency and the California Department of Public Health are the agencies responsible for establishing and enforcing drinking water quality standards. ETWD’s staff continuously monitors the water supply, conducting approximately 12,000 water quality tests each year from 70 representative sample locations throughout the District. We are proud to have a state-of-the-art Water Quality Laboratory that is state certified. ETWD is committed to delivering safe drinking water to your home or business.

This year, and previous years, Annual Water Quality Reports can be viewed by clicking the links below. For more information about this report, or your water quality in general, please contact Customer Service at (949) 837-0660.
