It's time for the "spring flush"... of pesticides

May 13, 2015 by Emily Marquez

What, you may ask, is the "spring flush?" In late spring and early summer, large concentrations of herbicides are flushed from croplands. These chemicals like the herbicide atrazine then get transported far and wide through surface water systems.

Herbicides are water-soluble and thus have the potential to leach into groundwater supplies as well as streams, lakes and other surface waters. Atrazine is a frequently found contaminant in drinking water supplies throughout the Corn Belt, and every year the spring flush raises concerns over the potential of atrazine spikes in drinking water supplies.
