Mitch Smith: Conflict between Farm and City Water

New York Times:

The flat, endless acres of black dirt here in northern Iowa will soon be filled with corn and soybean seeds. But as farmers tuned up their tractors and waited for the perfect moment to plant, another topic weighed on their minds: a lawsuit filed in federal court by the state’s largest water utility.

After years of mounting frustration, the utility, Des Moines Water Works, sued the leaders of three rural Iowa counties last month. Too little has been done, the lawsuit says, to prevent nitrates from flowing out of farm fields into the Raccoon River and, eventually, into the drinking water supply for roughly 500,000 Iowans. The suit seeks to make farmers comply with federal clean-water standards for nitrates that apply to factories and commercial users, and requests unspecified damages.

No price signals to farmers for their export of pollution downstream, so other legal means are being explored to address degraded water quality,
