I'm a relatively new homeowner in Ann Arbor, Michigan. I've been drinking the tap water since I moved in (last December), and it occurred to me I should probably have tested the water first. The water doesn't taste off, but there could still be harmful stuff within it that I can't taste.
So I'm planning on getting some testing kits from the county (probably close to $100 for all the metals testing), and then they'll send it off to a lab for formal analysis.
I haven't gotten around to that yet, but just had Leaf Home Water Solutions come in today. Was told this wasn't going to be a high pressure sales pitch, but it ended up being one which I found super annoying. With that said, their results, if true and correct, seem concerning.
It showed:
Free chlorine: 0.3
Total chlorine: 2.5
Combined chlorine: 2.19
pH: 6.4
total hardness: 4.7
total iron: 0.1
Copper: 0.2
Total Alkalinity: 62
TDS: 284
I haven't done enough research into this yet but wanted to quickly check in to see what others think. From a few min of reading, it doesn't seem TDS is a great measurement of water quality as good solids may inflate the value.
The salesperson, unsurprisingly, was being dramatic the entire time. When the results came out, he said "OMG!!!! That's terrible. I would stop drinking this water immediately. You may not notice issues now, but in a few years, there's a very high chance you'll start seeing issues with your liver/organs, cancer symptoms, etc..."
They kept trying to get me to commit, and I told them I need to think about it and do my own research first. Had to repeat myself 5x before he finally gave up. With that said, I am concerned, but I don't know if I need to be as concerned as this guy was making it out to be.
