Oregon Drinking Water Protection Program

Oregon implements drinking water protection through a partnership of DEQ and the Oregon Health Authority. The program provides information about drinking water, helps Oregonians get involved in protecting drinking water quality.

DEQ and OHA encourage community-based protection and preventive management strategies to minimize risks to public drinking water resources from future contamination. For help in developing and implementing drinking water protection strategies, please refer to the contacts and resources page.
