I can offer a few things on drinking water. First off is the water in town is high in mineral content (hard water). You may want to invest in a water softener if you want to extend the life of your water heating appliances. Particularly if you have an on demand hot water heater. Hard water can be brutal on these types of units.
As for testing the water, yes they pass the tests they have to send in. If you look up test results you will find they only regularly test for E. coli and Coliform bacteria. There are also lots and lots of things in the water that are never tested for. There are many different drug compounds being detected in our waterways because sewage treatment plants do not remove them.
For me, I use a reverse osmosis system in my home for drinking water and only drink bottled water from companies that use municipal water and further filter it. I do not use bottled spring water as they actually have fewer quality standards than most municipal systems.
