us geological survey http://kbia.org en Scientists detect high levels of nitrogen in Midwest waterways http://kbia.org/post/scientists-detect-high-levels-nitrogen-midwest-waterways <p>This spring and summer, U.S. Geological Survey scientists <a href="http://harvestpublicmedia.org/article/scientists-check-corn-belt-waters-effects-ag-runoff">waded into 100 Midwest streams</a> to test for hundreds of chemicals used in farming, including nutrients, pesticides like atrazine and glyphosate, and livestock hormones. The results from the study are trickling in. But preliminary findings indicate that from May through early July, 21 percent of the region’s streams contained very high levels of nitrogen in the form of nitrates.</p> Tue, 27 Aug 2013 14:39:02 +0000 Abbie Fentress Swanson 39487 at http://kbia.org Scientists detect high levels of nitrogen in Midwest waterways Scientists check Corn Belt waters for effects of ag runoff http://kbia.org/post/scientists-check-corn-belt-waters-effects-ag-runoff <p><span style="line-height: 1.5;">Eleven miles northeast of Centralia, Mo., five U.S. Geological Survey scientists don waders and bright reflective life jackets to wade into </span>Goodwater<span style="line-height: 1.5;"> Creek.
