Nitrates

The City of Des Moines’s water utility is trying to sue 10 drainage districts in northwest Iowa in federal court, accusing the districts of polluting the Raccoon River. But first, Des Moines Water Works must convince the state Supreme Court that drainage districts can be held liable.

The drainage districts assert that for over a century, the Iowa Supreme Court has held that they can’t be sued for a civil wrong due to their limited authority. Attorney Michael Reck told the court during oral arguments Wednesday that it should stand by its previous rulings.

  New figures from Iowa’s Department of Agriculture and Land Stewardship show 1,800 Iowa farmers have taken advantage of $3.5 million in state money meant to reduce pollutants from their fields. The state’s largest water utility says the figures divert attention from Iowa’s slide toward accepting environmental mediocrity.

  The state’s largest water utility is restarting its nitrate removal equipment because levels of the pollutant are spiking in the rivers Des Moines uses for drinking water. 

The Des Moines Water Works recently sued three northwest Iowa counties (Sac, Buena Vista and Calhoun counties) saying water from agricultural drainage districts contributes to the high level of nitrates.

It’s that time of year when Midwest farmers are preparing to plant their crops. This year though more may be thinking about the water in their fields, that’s because a lawsuit by Iowa’s largest water utility is targeting the nitrates farms send downstream and polluting the Des Moines metro's drinking water sources. Local governments and big agriculture interest groups alike are now watching this lawsuit.
