Well in my part of Floriduh, I do indeed have a well. It was tested and catalogued by the State. (looking mostly for agricultural runoff, but they did a full analysis).I'm not on a well here in Floriduh but the water in hard anyway even washing the car requires a wipe down with a spray wax to keep the spots off of it.I would hate to use it on my records.
I still have some too and it works so far. RIP Lou
But the water has a lot of calcium. NOT SO GOOD! Over the years it actually turned my black goldfish pond liner white.
When I wash a vehicle, I chamois it down as soon as possible "spread the wealth" as it were.
But, the Florida aquifer is basically riding through limestone, which can be > 30% calcium carbonate I believe.
