Idaho News
Spokane Public Radio The new study says heavy metals, phosphorus levels are steadily decreasing. Doug Nadvornick/Spokane Public Radio A National Academy of Sciences draft report concludes the quality of the water in Lake Coeur d’Alene has improved over the years. The report was shared this week at a symposium in Coeur d’Alene. Dan McCracken from the Idaho Department of Environmental Quality says the study found that the main sources of pollution — heavy metals and phosphorus — are entering the lake at lower levels than in the past. “Although we are still a long ways away from where we want to be, we’re starting to see some water quality improvements, just in the last five-to-10 years. Metals loading, coming from the upper Coeur d’Alene River, has consistently been improving since…

Water alternatives presented to Moscow leaders

Idaho News
By Anthony Kuipers; Moscow-Pullman Daily News The Palouse Basin Aquifer Committee presented its report on alternative water sources to the Moscow City Council on Tuesday in an effort to inform city leaders about ways to slow the aquifer’s decline. PBAC hired Alta Science and Engineering Inc. as a consultant to analyze the four alternatives. The recommended alternative is to divert water from the South Fork of the Palouse River in Pullman eight months out of the year, and divert water from Moscow’s Paradise Creek four months out of the year. It was the option that scored the highest based on criteria that includes cost and reliability. During a July PBAC meeting, Alta’s water resources division manager Robin Nimmer said this option had the least expensive capital cost of $73 million…

Finding an alternative water source for the Palouse

Idaho News
Moscow-Pullman Daily News The Palouse Basin Aquifer Committee is currently evaluating additional water sources for Latah and Whitman counties. Robin Nimmer, a senior hydrologist in the Water Resources Division at Alta Science and Engineering, spoke at the League of Women Voters of Moscow speaker forum Wednesday about how to ensure a lasting supply of water for the communities. "We've known about water level decline for a very long time," she said. "The wells aren't flowing anymore and we actually have data that shows us the water level is declining in our aquifer." Nimmer has recently been working with the Palouse Basin Aquifer Committee, which was formed in the 1980s, to evaluate alternative water sources for the region. The committee's mission since its start has been to plan for continued use…
