Dug well here was dug around 1964, as far as I know the water has never been tested. Never has given me any trouble but I quit drinking it a few years ago because of all the stuff on the news about possible issues. There is free spring water about 12 miles from here so that’s where I get most of my drinking and cooking water from, it was upgraded by the state probably 20 years ago and supposedly is some of the cleanest water in the state of Wisconsin, it’s out in the middle of nowhere and every time I go there are other people there filling up with water. Yes I am aware if I ever want to sell my place the dug well and septic system will most likely cause problems for people needing to get a loan from a bank. They say around here any time property changes hands the state gets involved and comes out to inspect stuff and that causes all kinds of trouble.
