Iowa Faces a Reckoning over Water Quality and Cancer Rates in Midterm Campaigns
Candidates are pressing for stronger runoff controls as Iowa reports the nation’s second-highest rate of new cancers.
Problems that have simmered for decades—water quality and cancer rates—have been forced to the forefront of Iowa state politics this year, with candidates from both parties making these issues central to their campaigns.
Chemical fertilizers and animal waste contain nitrates that wash into rivers, creating tension between Iowa's urban centers relying on drinking water and agricultural producers upstream.
Democrat Josh Turek linked clean water to cancer rates last week while speaking with cancer patients; Republican Zach Lahn has diverged from peers by directly connecting polluted water and agrochemicals to Iowa's cancer crisis.
In May, Republican Gov. Kim Reynolds committed $320 million for water infrastructure and conservation projects, with funding directed to utilities like Central Iowa Water Works that operated nitrate removal systems for a record 193 days straight.
The Environmental Protection Agency does not currently classify nitrates as a cancer risk despite ongoing scientific analysis, maintaining the issue as a point of intense political debate across the state.
