What We Do

Community Clean Water Institute (CCWI) protects water resources and public health, identifies pollution sources, and works to prevent water pollution throughout Northern California. CCWI collects and analyzes water quality data, conducts research, participates in education and community outreach activities, and shares information with government regulatory agencies and the public.

Community Clean Water Institute has developed a water quality testing program and laboratory to test ground, surface, and drinking water sources for a variety of pollutants and makes all of the findings available to the public. CCWI works with grassroots watershed groups and other non-profit organizations to address issues of clean water and public health. When an individual reports suspected pollution, CCWI investigates and conducts initial analysis and then decides whether or not the area needs to be regularly tested.

CCWI evolved from the Water Committee of the Town Hall Coalition, a group of citizens concerned with water quality, and interested in increasing the amount of scientific data on water quality of rivers, streams, and groundwater. The Water Committee collected water quality data and performed water tests from 1998-2000. In March of 2001, CCWI was founded as a separate 501(c)(3) non-profit organization.

Community Clean Water Institute focuses on the rivers and counties within the North Coast Regional Water Quality Control Board (Region 1). The Institute focuses on water quality and possible contamination of surface or ground water in Sonoma County, but may also survey Marin, Mendocino, Humboldt, Del Norte, Trinity, Siskiyou, Glenn, Modoc, and Lake counties. The organization works to protect water quality in the watersheds of the Eel, Russian, Van Duzen, Trinity, Mad, Smith, Klamath, Gualala, Navarro, Albion, Noyo, and Mattole Rivers and the other magnificent rivers, bays, and wetlands in Northern California.
