Well Disinfection (PDF): If your well is impacted by flooding, you may want to "shock" your well after the water recedes. Please follow these disinfection instructions.

After shocking your well wait at least 5 days for the best chance of determining whether the contamination problem is on-going as opposed to being caused by the flooding. Have your water tested again by a certified laboratory for bacteria. See this link (PDF) for more information.

DEP recommends that private wells test negative for coliform bacteria. The presence of coliforms indicates that unsanitary conditions and/or disease producing bacteria and viruses may be present. Continue to use boiled (boiled for 1 minute at a rolling boil) or bottled water until your well water is free from coliform bacteria. Boiled or bottled water should be used for drinking, cooking, food preparation, dishwashing, making ice and coffee, mixing baby formula and brushing teeth.
