line your well
Sorry to be responding so late on this but who knows, it may still help you or someone else.
MY PROBLEM: (if anyone cares! haha)
As it turns out, I have a different problem which requires a similar solution. I THINK I'm getting ground water into my well. My chloride levels are high enough to taste and I'm getting very cloudy water, especially after a soaking rain. We've been filtering our drinking water with R.O. and the whole house with a 20gpm particulate filter. Rather than drill a new well, I've been wanting to repair this one. First, I wanted to see what was going on down there. I ran the water to bring the head down, then lowered a camera/flashlight on a string. I used one of those helmet cams. I was able to get a great video of the inside. It looks like mine's leaking groundwater where the casing meets the bedrock. Anyway, that's MY issue. We both need our wells lined to fix them.
TWO SOLUTIONS: (according to my well guy with 40+ yrs experience)
1. Sleeve the well with 6" O.D. PVC. This is a "one way trip" as the PVC can never be removed. It must be done with a derrick. The PVC is pressed into the casing.
2. Insert a smaller Diameter PVC. I don't remember the size, but my well guy says it's plenty to allow for a pump. There's a rubber gasket between the PVC and the casing which seals out bad stuff. The way I see it is, even if it seals out 70 or 80%, it's WAY better than it was. depending on your problem, this may provide part of a two step fix, i.e. installing some filtration inside etc.
I haven't done anything yet, but will post when I do.

My home's well has a 6 inch galvanized casing that is about 50 years old. We have some issues with rust coming out of the well. I was thinking that in the future when the submersible pump is replaced it might be a good idea to install a new PVC casing inside the existing galvanized casing.
I'm wondering if this is something that is ever done or if anyone sees any problems with the idea? The one issue I see is that the pitless adapter will need to be dug up and fitted in the new casing. On the other hand it will probably be time for a new lateral (if we are going to do it right anyways).[/QUOTE]
