Amanda Winkelmann held up a baby bottle filled with tap water as she spoke at the Iowa Capitol Thursday about the need for greater attention to Iowa’s water quality.

“If we could see it,” Winkelmann said and used a paintbrush to put a drop of pink paint into the water. “Would we solve it?” 

Winkelmann, who lives in Des Moines, said she and her husband choose to refill water jugs with filtered water due to their concerns about drinking tap water that has consistently high nitrate concentrations.

She was one of more than 150 Iowans gathered in the Iowa Capitol Rotunda Thursday afternoon urging lawmakers to support bills that would improve Iowa’s rivers, lakes, streams and drinking water.

Water quality has been a major topic in the state among environmental advocates for years, who have warned about the impacts of farm runoff and chemicals like PFAS in the state’s water. But these concerns have been further elevated in the past year as central Iowa faced elevated nitrate levels in the Des Moines and Raccoon rivers in 2025.

A new Iowa Environmental Council (IEC) report issued Tuesday (July 16) paints the NRS as a very slow road to nowhere.
