Judge dismisses Des Moines Water Works lawsuit
A U.S. district judge rejected the legal underpinnings of the Des Moines Water Works' lawsuit that sought to hold drainage districts in northwestern Iowa responsible for nutrient runoff from farms. The judge dismissed the case, ending the chances for a precedent-setting interpretation of clean-water laws. Agricultural runoff generally is exempt from the water pollution laws, but the Des Moines utility argued that the drainage districts were identifiable "point" sources of pollution and should be required to meet clean-water standards.
