So I am getting a plastic off-taste in my IPA that I kegged two weeks ago, and I am trying to pinpoint whether it could be my water or keg, tubing, infection, etc.
Anyway, I had a question on chlorine levels in the Boston water report, found here:
The 3rd to last page page says Minimum Residual Chlorine for Boston is 0.25 ppm, but the Average Residual Chlorine is 1.85 ppm, which I though was extremely high as I had the understanding that anything over 0.5 ppm was high.
Also, on the water quality page (last page), it doesn't show any values for Chlorine under the Wachusett system (which feeds Boston), except for "Chlorine, Total" of 2.9 ppm (which is also high?).
However, I was reading another post, here
, that said MWRA doesn't use chlorine, they use ozone and chloramines as disinfectants, so there shouldn't be any chlorine in the water.
Anyway, long story short, does Boston have high chlorine levels? I am guessing no since I know the Sam Adams brewery in Boston uses city water and they claim not to treat it at all. But on the other hand, the report above seems to say yes.
Any help would be appreciated!
