In the Heart of the Corn Belt, an Uphill Battle for Clean Water

Runoff from farms and feedlots has badly polluted Iowa’s waterways, more than half of which do not meet federal quality standards. Now, an unlikely coalition is calling for stricter controls to clean up the drinking water sources for millions of the state’s residents.

Runoff from farms and feedlots has badly polluted Iowa’s waterways, more than half of which do not meet federal quality standards. Now, an unlikely coalition is calling for stricter controls to clean up the drinking water sources for millions of the state’s residents.

“Health trumps politics,” said Iowa State Senator David Johnson before taking the stage at a raucous rally in Des Moines last winter to support strengthening the state’s water quality. In the marble rotunda of the state capitol, he rose to denounce the nitrogen and phosphates that have been flowing in ever-increasing quantities into Iowa’s public water supplies — and was cheered by the small crowd of family farmers, concerned mothers, and his new political allies, the legislature’s drastically outnumbered Democrats. Johnson had been one of the longest-serving Republicans in Iowa until he left the party to become an independent in 2016 after defying it repeatedly on one of the most divisive issues in Iowa — the integrity of the state’s water.
