Well bummer….
I just got those tests back, and I have MAC in our water even with a deep well, UV system, and 140 hot water.
Oddly, my tub and shower water didn’t have MAC
but kitchen and bathroom sink hot water (same room as shower and tub) did have MAC.

Thankfully, I haven’t been drinking the kitchen faucet water as we filter our drinking water through a Berkey filter machine. I am going to have THAT water tested now.
Rats………
