Scientist presents major groundwater quality analysis for south central Idaho
By Rachel Cohen; Boise State Public Radio News A water quality sampling line is fed down a groundwater well in southern Idaho. Idaho Water Science Center USGS Water in south central Idaho has had nutrient issues for a long time. That’s according to Kenneth Skinner, a groundwater hydrologist at the U.S. Geological Survey. But Skinner said, while several state and federal agencies have collected data in the Magic Valley area since the 1990s, there hasn’t been a recent analysis of regional groundwater contamination trends. That’s what he set out to complete by analyzing samples of a particularly widespread pollutant, nitrogen, from over 500 groundwater wells. Some common sources of nitrogen are fertilizer and manure. His findings, shared at the Idaho Water Quality Workshop on Wednesday, show nitrate levels in the Magic…
