Atrazine Container A container of household Atrazine weed killer.

Atrazine is an herbicide used against broadleaf and grassy weeds in crops. The chemical makes its way into our water supply through leaching—runoff water from rain or irrigation flows into the soil, where the chemical dissolves and is carried down into the groundwater connected to wells and springs.

While it’s been banned in Europe, atrazine is the most widely used herbicide in the United States. Many researchers have been calling for its ban in America, due to possible endocrine effects, carcinogenic effects, and connection to low sperm count in men.
