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.
