First, ground conditions in Cali or Fla or Ga will be no help in Erie PA. The wells I had 100 miles south of you in PA won't tell you anything, different geology. Best bet is to talk with a well driller familiar with your area, they'll know exactly whats happening. If you don't want to do that talk with as many neighbors with wells as you can. It may need cleaned out. Is it possible in the area to use straight well water or does it need treated? Where I lived all well water had to be treated.
