Gallery: Tainted water in farming communities is complex issue

4:07pm

The nitrate-removal system -- now woven into the infrastructure of this heavily Dutch settlement - reflects a dilemma that is spreading across Minnesota farm country: Corn and soybean fields pump money into local economies, while pumping unwanted chemicals into the groundwater. Edgerton's history with the problem provides a vivid example of the link between farming and tainted water - but also the reluctance of small-town Minnesotans to point fingers where their neighbors are involved.
