I recently had my well water tested and it came back positive for e coli. I believe the source of contamination is surface water entering the well through the line that feeds the house. To confirm this theory, I dug a 12-18" hole above the pipe to the house just outside the well apron. I ran a garden hose in the hole, and water did begin to trickle in around the pipe. It also flowed in at the casing seam at about the same depth as the pipe. The casing is made up of concrete sections about 2' high by about 3' diameter. The pipe to the house is about 30" below ground, I'd guess.
I spoke with a couple of well contractors. One said they'd dig down to the supply line and patch from the outside. The other said they just patch from the inside. When I expressed concern about how well it would hold, he said they patch the casings like this routinely and have never had one leak. I'm interested if anyone has ever tried patching the casing from the inside, and if so, how well it works. Also, if this is a good idea, what type of patching material should be used?
I'm pretty new to the mechanics of wells, so any advice is greatly appreciated.
