Yikes — it turns out there's a lot of hormone-disrupting junk running straight from your faucet and into your glass. Atrazine is a widely used pesticide, which means it often sinks into the ground and contaminates drinking water. That would be OK — if it didn't cause chemical castration! That's right: atrazine has caused feminization and chemical castration in frogs, an effect that applies in varying degrees to all vertebrates. So stick to certified organic pesticide-free produce, support organic farming and buy a good water filter!
