State lists don't usually change every year. There is usually substantial process that needs to happen to make a change. Does not surprise me at all that nothing has changed in several years. Ohio's is reviewed every 5 years.
Great Lakes pH

I think it just the limestone. My water comes from wells in limestone. My local creeks are mostly limestone. Both are right about 8.3.
Interesting thing about my well water I use for my fish systems:
It comes out of the ground at 7.5 but jumps to 8.4 after vigorous aeration. Apparently due to the release of CO2? All my outdoor ponds are in the 8.4 range. Soil is also very alkaline. Limestone layer is about 400 feet down. Aquaculture well pump is set at 44 feet in an 88 foot well.
My alkalinity is so high (350 mg/L) it's a bitch to get the Ph down in my swim spa with Muriatic acid and keep it there. Same goes for my past aquaponics systems.
