I have a private well dug in 1975 it is 194 ft deep. The old well was very good water. We did not hit the same 'vein' so not quite as good. I filter my water but it needs to be replaced. Considering putting in a whole house filter. I have a water softener also.
Use Miracle II products. Have a laundry ball so don't need to buy laundry powder. Saves lots of money. Also use a new product that puts more oxygen in my water.
