Cyanobacteria (Blue-Green Algae) Program

The Columbia River is the main source of drinking water for Richland, West Richland, Pasco, and Kennewick. In summer 2021, algal blooms on the river resulted in the detection of anatoxin-a in water samples. The Cyanobacteria Program monitors and responds to future algal bloom events on the river.

Water Quality

Monitoring and controlling backflow and cross connections are crucial elements of maintaining water quality. Learn more about these processes below.

Cross Connection Control Program

A cross connection is any connection where non-drinking water could enter a water system. The Cross Connection Control Program protects the public water system from contamination via cross connections. Learn more about the program and related procedures here.

Backflow Prevention

A backflow preventer keeps drinking water from becoming contaminated. Backflow preventers are installed at cross connections to prevent contaminated water from flowing into your drinking water system. Read more about the importance of backflow preventers here.

The City maintains a list of approved backflow testers. To ensure your backflow prevention system is working properly, have your system tested regularly.
