Drinking Water

DEQ’s Drinking Water Bureau protects public health by ensuring drinking water from public water systems is safe and reliable. We work closely with the state’s public drinking water systems to protect drinking water sources, monitor for contaminants, inspect water systems, and review system engineering.

We carry out this work in partnership with Idaho’s seven public health districts. Together, we provide a variety of technical and compliance assistance to public drinking water systems to ensure compliance with state requirements.
