Same's true here. I still filter or boil it. It's just to ingrained in me not too, but I'd love to have the water tested from a few of the places I go often just to know for sure.

For years, when I was a kid growing up in No IL, the government told us we had an aquifer with water that was over 2000 years old and pure as arctic ice. Some of it came out in artesian springs. People used to go to one of them and fill jugs and bring them home. I drank out of it when I was a kid. Turns out that pollutants did seep into it before it got to us.

Around here (the Ozarks), water can flow for miles and miles underground. I do know that local wells have very pure water, and that makes me feel better, but I'll never be completely confident again without testing the source.
