7.1-8.7! That’s a huge range.

Not to mention hardness of 60 to 200 ppm.

Those ranges are difficult to deal with. According to the information, two creeks supply the water. Interesting there is that much variation; I wonder if it is seasonal.

They do add something to maintain pH for corrosion control. It would be worth finding out what, exactly; I have soda ash added here in Greater Vancouver, which dissipates out fairly quickly so it is not a problem for fish. Could you see if there may be more info on this (and maybe the GH variation) on that "American Water" website they mention near the end?
