Water Quality & Testing

Clackamas River Water member’s drinking water is closely regulated by both the Environmental Protection Agency (EPA) and the Oregon Health Authority (OHA). Water Provider staff and testing experts conduct more than a thousand tests every month in our source water, drinking water treatment plants, and in our distribution systems. This continuous monitoring of quality and safety, ensures that our drinking water more than meets strict federal and state drinking water standards.

A few examples of required water quality testing are:

• Coliform Bacteria.

• Inorganic Compounds & Radionuclides – Nitrates, manganese, other simple chemicals and minerals, and radium.

• Volatile Organic Compounds (VOCs) – Solvents, cleaners, pesticides, and other man-made contaminants.
