Septic and Well Safety
During a Natural Disaster

After a natural disaster such as Tropical Storm Irene, it is important to consider the safety of your wells and septic systems. If you suspect that your well has been contaminated or that your septic system in malfunctioning, it is imperative that you take the following steps to insure your well and septic system are safe.


If there is suspicion that your well may be contaminated (dug wells or drilled wells where the cap was partially or completely submerged), do not drink the water ; it is advised that you have your well tested. For a list of local certified labs for testing well water, click here.

Once your well has been tested and there is evidence of bacterial contamination, you will need to decontaminate it. For information on how to disinfect your well, click here

In addition, this is a good opportunity for a dug well to be upgraded to a drilled well, buried well caps be extended 6” above grade with a sanitary well cap, or a property be connected to public water (if applicable). Please be aware that all of these require a permit from a licensed well driller for upgrade and/or abandonment of existing wells.

Septic Systems:

Several septic systems can become inundated and or backed-up into houses due to the flood. Unfortunately, time is the best remedy for this, i.e. wait for the water to drop and eventually the leaching system will start to dry out and become functional. We recommend systems that were inundated or backed-up into houses be inspected by a licensed septic installer as soon as possible.

If sewage backs up into the house, it should be pumped out and all surfaces that are smooth and easily cleanable should be cleaned with a bleach solution. All non-cleanable surfaces should be discarded. It is recommended that sewage back-ups be cleaned by a professional cleaning service.

Should you have any further questions or require assistance, please contact us at (860) 448-4882 and ask for a sanitarian.
