There’s a killer in Iowa’s water, and it doesn’t come from a factory smokestack or a chemical spill. It comes from the very fields that built the state’s identity and its economy.

Iowa now has the fastest growing cancer rate in the nation and the second highest overall. For young adults aged 20 to 39, the numbers are even more alarming: the state ranks second nationally for new cancer diagnoses in that age bracket. An estimated 21,700 Iowans will be diagnosed with invasive cancer this year alone, with 6,400 expected to die.

Politicians and industry lobbyists reach for the usual scapegoats binge drinking, obesity, too much sun. But a growing mountain of evidence points to something far more systemic: the chemical saturation of Iowa’s land, water, and air by industrial agriculture.
