For those of you with wells, you know that sometimes they need treating for the water to be safe. Especially for consumption by kids and the elderly. In the situation where the Culligan Man may not be available to do so, and you may have nobody to test your water anyway, you may want to treat it on your own. The chemicals (chlorine?) to do so are available to treat your well, and should only cost $10-15 per treatment. My local bottled-water place sells it, so I only assume yours does too.

Won't bottled Bleach do the same thing?

You know it might, but I'm not an expert on this sort of thing. The stuff comes in a little plastic container in pellet form sealed tight, so it looked like it would last a long time. I kind of figured for the $12 it would just be worth it to buy the stuff.

Have a sample of your well water tested BEFORE you drop liguid bleach into the well. The company that I used to work for did that and ended up with more problems than before.

Wouldn't you be better of treating After it comes out of the well?

I think you would be wiser to get a good filtration system (UV), instead of maybe ruining a whole well system.

Man, I have to agree with North Force, My well goes into a giant underground lake, millions of gallons of water. It seems to me even a small well that is in the rocks that only produces 3 or 4 gallons a minute, still better to treat water after drawn. Unless your problem is a dead animal, or feces in the casing itself. I'd treat the water after you pump it. If your problem is the later, then you'll have to treat it in ground. Maybe your well are different then mine. I can treat a problem in the casing, but would be wasting my time trying to treat the aquifer.

The most common problem is coliform in the well casing itself if I understand correctly. The water is fine, the contamination occurs from contact with bacteria built up in the casing. Full-spectrum testing kits can be had for about $25.

This is a comprehensive write-up. Good read. Well disinfection procedures

So if i understand that info - you only want to treat/kill the stuff that is in your "Water Pipe" in the well, not the well it self.

Yup, it's not possible to treat the groundwater. If you have a problem with the actual water, you have no choice but to treat it above ground. Most common groundwater contaminants are nitrates, pesticides, and heavy metals. In the city the most common contaminant would be fluoride.
If your well water tests good it should theoretically stay good barring no major changes to your area like new livestock farms or flooding. Talking about the actual groundwater now, not the well piping. That being said the safest way would be to treat all of the water that came out of it. CDC recommends testing at least once per year. Best in our situation to be prepared to test and treat it I suppose, for when things go south.

Now to find a good filtration and UV purification combo that can be run without electricity and can treat mass amounts of water.

Also you should insure that your well is at least 200 feet from any septic system or animal corral and pens...A lot of people are that far from their own septic but the new neighbor septic can intrude in that space. Hey 200 feet is the legal min. here I would want to be a lot farther.
