My drinking water today measured:
FC: 1.0 - 0.5
Should I call the water department? Or am I just bad at that color test? I can do an FAS-DPD test to verify the chlorine numbers but the PH is all color based and while I think I'm right it could be a between 7.8 and 8.2.
A few days ago I checked my father-in-law's drinking water and it measured:
FC: 1.5 (FAS-DPD measured)
EDIT: Hummmmm... I found some sources that say that PH can be as high as 9 in municipal water systems...
