Status: No national drinking water standard exists

 

Ethinyl estradiol is one of the 3 types of estrogen made by the human body. Sex hormones get into water downstream from livestock and pharmaceutical production, or incomplete removal in waste water treatment. There are no standards to gauge how risky additional hormones are for human health.
