Flooding makes Connecticut well water contamination a real concern. Floodwaters often carry bacteria, parasites, viruses, and chemical pollutants. If your well is shallow or the casing has been breached, those contaminants can invade your water supply, putting your family’s health at serious risk.
Important Safety Steps If Your Well Is Flooded
If your private well has been affected by flooding in Connecticut, do not drink, cook, or bathe with the water until it’s been properly tested and cleared.
Follow these critical steps immediately:
- Stop using your well water. Floodwater can carry bacteria like E. coli, viruses, and chemicals that pose serious health risks.
- Contact a professional well service. A licensed Connecticut expert can assess for damage and contamination.
- Test your water. The Connecticut Department of Public Health recommends a full water quality test, including coliform bacteria and nitrates, after flooding.
- Disinfect your system. If contamination is found, your well and plumbing may need chlorination or other treatments before it’s safe again.
Tip: Even if floodwaters didn’t reach the top of your well, groundwater changes can still affect its safety.
What To Do If Your Well Has Flooded in Connecticut
If your well has been exposed to floodwater, quick action is essential. Contaminated well water can lead to serious health problems, even if the water looks clean. Follow these steps to protect your water supply and your family.
1. Stop Using the Water
Do not drink, cook with, or bathe in water from a flooded well. It may contain:
- Bacteria, such as E. coli
- Viruses
- Chemicals like pesticides, oil, or other household waste
2. Inspect the Well
Check for visible signs of damage to your well cap or casing, electrical system, and pressure tank. Even if everything appears intact, you want to make sure you contact a professional well contractor to perform a proper inspection of your well.
3. Get the Water Tested
After flooding, your well must be tested by a certified lab. Schedule testing as soon as floodwaters begin to recede. Important tests include coliform bacteria, nitrates, and other potential chemical contaminants. The Connecticut Department of Public Health or your local health department can direct you to approved testing labs.
4. Disinfect the System
If the test shows contamination, the well and possibly the plumbing system need to be disinfected. This may include:
- Shock chlorination
- Flushing the system
- Professional follow-up treatment
Do not attempt to disinfect your well without expert guidance, as incorrect treatment can make the situation worse.
5. Retest Before Use
Water must be tested again after disinfection. Do not resume normal use until you receive at least two clean test results confirming the water is safe.
Preventing Well Flooding in the Future
While not all flooding can be avoided, there are smart steps you can take to protect your well from damage during heavy rains or rising groundwater:
- Ensure proper well construction: Wells should have a sealed, raised cap and be located uphill from runoff-prone areas.
- Grade the soil around your well: Sloping the ground away from the casing helps divert surface water.
- Schedule regular inspections: Annual maintenance can catch problems before they become emergencies.
- Install a well vent screen: This prevents debris and insects from entering during storms.
- Know your water table: If you live in a flood-prone part of Connecticut, extra protection may be needed.
Tip: Document your well’s depth, construction date, and location. This helps professionals act faster in emergencies.
