1935 - 2007: Dropping water levels.
Water levels in the Grande Ronde Aquifer are declining 1.5 feet per year -- jeopardizing the long-term future of communities that rely on this sole source aquifer. The Palouse groundwater basin is the sole source of water for over 50,000 residents of Pullman, Washington and Moscow, Idaho and outlying areas in both Whitman County (Washington) and Latah County (Idaho). Washington State is permitting this Aquifer to be mined in violation of state law.
