Why does San Francisco put anything in the water? It has some of the best tap water in the country. Hetch hetchy water exceeds all federal and state criteria for tap or bottled water. Raw.

I don't get why people think that water is somehow safe because it comes from some magical place. Water still needs to be transported 167 miles from HH, during which it can pick up plenty of things, like lead, chromium 6, bacteria and all sorts of other fun stuff. Never mind it has likely sat in a local reservoir for some period of time and who knows what the condition of those things are. Before it was chlorine and then apparently that wasn't enough, so they switched to chloramine. Then, they do shit like this, with some weird spin on it: https://www.sfgate.com/bayarea/article/SF-s-pure-drinking-water-to-get-a-new-ingredient-10949336.php https://www.sfgate.com/bayarea/article/SF-s-pure-drinking-wa... I had several fish tanks (one ~400 gallons) that I was caring for during that switch over. I tried to do filtration and additives and the fish were never the same, they all died. It just seems intuitive that adding something to water that kills fish almost instantly, couldn't be great for humans either. Needless to say, I only drink RO water, put a filter on my whole house and in my shower. That probably isn't enough, but at least it is better than nothing. https://www.epa.gov/dwreginfo/chloramines-drinking-water https://www.epa.gov/dwreginfo/chloramines-drinking-water https://19january2017snapshot.epa.gov/www3/region9/water/chloramine.html https://19january2017snapshot.epa.gov/www3/region9/water/chl...

  HH water runs inside pipes almost the whole way. It's not picking up much. Are you drinking local RO water? Like rain off your roof? Isn't that full of local smoke particles?

    Maybe reverse osmosis water?

      I concede that bacteria may get introduced during final distribution. There is less smoke pollution in the HH area than right here in the bay area where everyone is running their cars all the time.

Since this article was written, there have been fires almost every year. The water also moves from HH to other reservoirs along the way. Let's also not forget that the dirty air from SF, blows east. I also wasn't talking about rainwater, I was talking about reverse osmosis.
