The Palouse Groundwater Basin is the sole source of drinking water across eastern Washington (Pullman, WA) and northern Idaho (Moscow, ID). The Palouse Basin Aquifer Committee (PBAC) is a consortium of public entities including cities, counties, and universities, along with the respective state water agencies. By working together, their goal is to implement the Palouse Basin Groundwater Management Plan, enacted in 1992, by analyzing and researching the Palouse Groundwater Basin. The Committee monitors groundwater levels and annual water usage, continually advocates for education opportunities within the community, and explores implementing supplemental water sources.
