Gain access to the inside of the well to add the chlorine. Add the chlorine, then using a hose from the nearest faucet, allow water to run into the well two to three hours to circulate the chlorinated well water.
Discontinue using the water hose. Water should be pumped throughout the system until the chlorine odor is noticed at ALL outlets of the system. The water should then be allowed to remain in the well and system as long as possible, preferably 24 hours during this time it is recommended that the water not be used for drinking or cooking.
After disinfecting the well, flush all faucets until the bleach odor disappears.
Resubmit another sample, keeping in mind that a single disinfection may not be sufficient and periodic testing is suggested.
