I think that's the most reasonable hypothesis I've heard: how could you flood the effluent stream with tons, literally tons of estrogen-estriadol and related hormones, and NOT get male fish with egg proteins in their testes, and sexually deviant amphibians (who are absorbing it through every pore) as well as sexual ambiguity and disorientation right up through the vertebrate population in the affected watersheds?
Any by the way, I've read that ALL the watersheds are affected. Don't have time now, but search with keywords like feminized amphibians contraceptive hormone --- well, here ya go, LINK!!
Ask any man you know, if he wants his sons wasting their lives in chronic gender confusion. Or if he wants eggs developing in his testicles.
