... for anyone who has a well and a septic tank, or drinks water from a river downstream of any larger urban area.
In many ways being downstream of industrial agricultural "farms" is worse. Somebody is supposedly responsible for monitoring the discharge of sewage treatment plants, but industrial agriculture is often like "Who me? Shucks, I'm just a farmer!"
Even giant multi-billion dollar agricultural corporations with executives wearing $10,000 designer suits and flying around in private jets play that farmer card.
It's silly to consider desalinization of seawater any better, considering all the crap we've dumped in the ocean, and are still dumping in the ocean.
Hell, Los Angeles used to dump sewage they'd simply screened out the worst of the garbage they didn't want on their beaches directly into the ocean, including waste from chemical manufacturers. The poor brown pelicans almost went extinct from the waste of DDT manufacturers, and PCB got into everything including nursing mothers' milk.
Heck, Los Angeles sewage may have made me the man I am today, a lowest tier mutant superhero sidekick with some very peculiar and mostly useless talents.
The sewage from my house gets recycled as "good enough to drink, bathe, or swim in" agricultural water. Some of the food you eat may have been irrigated with sewage from my house.
It's actually one of those odd "conservation" things in my life. I don't feel too bad about water that runs down my drain because I know it won't be wasted.
We have these last few years let our backyard lawn die, and we replaced our front lawn with low & no water plants way back in the twentieth century.
Okay, I'll confess, I'm not sure how much of the back lawn abandonment was for noble environmental reasons, or the fact that we adopted a husky from the animal shelter who likes to dig, most especially in the grass.
