WASHINGTON – Seasonal spikes of atrazine – a weed killer that can disrupt hormones and harm developing fetuses – contaminate drinking water in corn-growing areas of the Midwest and beyond, according to an analysis of federal records by the Environmental Working Group.

Environmental Protection Agency data show that in some Corn Belt communities, atrazine levels can spike three to seven times above the legal limit in late spring and early summer. But by avoiding water testing during peak periods, some water utilities stay in compliance with drinking water regulations – and don’t have to tell customers they were exposed to a hazardous chemical in their tap water.
