One procedure that will rid a well water system is "shocking" the well with household chlorine bleach to sterilize it. The first step would be to turn off the hot water heater, drain it, and allow it to refill with cold water since it isn't advisable to heat chlorinated water. Next remove the cap from the well head and pour 3 cups of bleach per 100' of depth directly into the casing. With a garden hose add about 5 or six gallons of water to help push the bleach down. Then starting with the closest outlet, slowly open the faucet and allow to run until bleach smell is detected. Shut off and go to next furest outlet repeating the open, smell, close procedure. Once the procedure is completed at the furthest faucet allow the system to set for an hour. The repeat steps and run until nor bleach odor is present.
The first time David and I went to Quebec to hunt caribou on the tundra we were in a camp with 8 other hunters. Each of them lived in towns with a municipal water system. Each hunter suffered from drinking water directly from the lake while David and I did not. I think it was because their daily consumption of chlorinated water had killed the naturally occurring bacteria in their digestive system while David and I, both well water drinkers, didn't suffer.
