Hope you’re checking those wells on a regular basis for water quality. Regular means more than once every5 to 10 years or whenever I get a round to it.
Municipal supplies are checked daily for water quality parameters.
I have my wells checked every year for heavy metals and biological contaminants. My big well is tapped into a limestone spring network. It'll do 48 gpm of crystal clear water that needs nothing. The other well isn't quite as deep and has some iron in it that is removed with some minor treatment, but it's good water, too. Much better than the crap in the municipal supplies around here that all come out of the Tennessee River, down stream of 3 nuke plants, a century after hundreds of tons of coal tar and other industrial chemicals were dumped into the river.....
“Municipal supplies are checked daily for water quality parameters.”
I have been the operator of a small water system for almost 30 years. 400 homes, 40 condos, and a couple of commercial connections. We have 4 relatively deep wells, 450 feet. The EPA requires that we test in the system and at the plant daily for Chlorine residual. Once a month for bacterial and ph tests. Inorganics, organics, radiological, metals , etc., are spread out over a few years. Lead and copper started out as 20 for the first round, then if you were in compliance, dropped to 10 the next year, then 5 every few years.
We treat with chlorine and phosphate. Over the last 30 years, there have been no detectable changes in our water. Fluorides can occur naturally, but in our system they’re in fractions of a part per billion. Our water is some of the very best in the state.
Still, I get my drinkin’ cookin’, and mixin’ water direct from the wells, pre-treatment!
