Atrazine in your water
Health effects
Atrazine is one of the most widely used weed killers and reaches water through agricultural runoff. It is an endocrine disruptor associated with reproductive and developmental effects, and concentrations tend to spike seasonally after application. It is most common in farming regions.

The federal legal limit is the maximum allowed by law. The EWG health guideline is what independent scientists consider safe — it is often far stricter.
