Note though that the stuff you drink from your tap is filtered and treated with chlorine more often than not. Granted, it is not "clean" for sure, but it isn't exactly crawling with E. coli and strangely enough, I've checked. You drink more mold from you faucet-head being dirty than bacteria from you tap water.

This IS a big deal, but unfortunately this video presents it so poorly that people won't buy it and will generally consider it as much as they consider PETA or other such groups... sad.

New studies are coming out frequently now that what we put down the drain is really hurting things... one very unexpected example is birth-control drugs. I didn't see this one coming, but it turns out that the boatload of estrogen going down the drain as a result of the drug might be tainting fish populations. It turned out in one river that a 10:1 female to male ratio had occurred in trout populations with an abundant amount of other mixed gender fish as well. I'll tell you now as a geneticist that 10:1 is NOT GOOD. WE NEED BETTER WATER TREATMENT!

"EPA estimates that about 850 billion gallons of untreated wastewater and storm water are released as CSO (Combined Sewer Overflow) each year in the United States"

So, the video is right (860 billion, 850 billion - close enough!) on at least one of its points.
