Our Aquifer


Postcard of the Portneuf River near Lava Hot Springs Idaho

The Lower Portneuf Valley Aquifer is the only source of drinking water for the Cities of Pocatello, Chubbuck, and north Bannock County. Because we live on top of the aquifer and because there is very little protective soil cover due to the geologic history of the valley, our water supply is vulnerable to contamination from human activities associated with industrial, business, residential, and agricultural practices.

Protect Our Aquifer…..We Drink It!
