{{{'Suela}}} I have no advice to offer on this one, but I hope you, your sister and your father can get some relief.
Perkins, I grew up with well water. Depending on the hardness, you may have to maintain a water softener. We also didn't drink the water--I tested the lead content for my science fair project, and the PPM was a good bit higher than acceptable. The well ran dry 15 years after they built the house and it was about $6,000 to dig a new one in 1990.
I was always under the assumption that when the power was out, so was the water. DH couldn't understand why I was yelling at him to not flush the toilet during the first power outage in our house. Even to this day, I still forget that I can brush my teeth and take a shower.
