Rain Worsens Nitrate Levels as Farmers Work to Reduce Runoff
Central Iowa Water Works has issued a lawn watering ban this week due to record-high nitrate levels in the Raccoon and Des Moines Rivers, which supply central Iowa's drinking water. On Wednesday, nitrate levels in both rivers exceeded the EPA drinking water standard of 10 mg/L, measuring over 13 mg/L in the Raccoon River and over 11 mg/L in the Des Moines River. This ongoing issue, exacerbated by recent rainfall, impacts the drinking water supply for communities in central Iowa, including Des Moines.
