Private Wells: Protect Your Family's Water

flooded street, child with water, private well cover

If your water comes from a private well, germs and chemicals can enter your drinking water from extreme weather, runoff, and natural changes in groundwater. Using contaminated water for drinking and preparing ice and food can make your family and pets sick. Babies, children, pregnant people, older adults, and people with health conditions are most at risk of health effects from consuming contaminated water. Learn more about how to protect your drinking water.

Protect Your Family's Water

  • Test your well water at least once a year for bacteria and for other contaminants every 3-5 years.
  • Test your water for E. coli and coliform bacteria after you disinfect and flush your well, or after you perform maintenance on your system to make sure problems are addressed.
  • Regularly check and maintain the well, system components, and area surrounding the well.
  • Test your water if you notice changes in how your water looks, smells, or tastes, after floods, changes in land use, or concerns about local contaminants.
  • If you suspect your well could be contaminated by gasoline, heating oil, or chemicals, contact your health department and the New York State Department of Environmental Conservation (DEC) Spill Hotline at 800-457-7362.
  • Keep records of maintenance activities and water testing.
  • Contact your health department for advice on maintaining, testing, disinfecting, and flushing your well.
  • Take steps to get connected to a public water system, if you have the opportunity. Public water is the best option for household water because it is regularly monitored and managed by a certified water operator.

Contaminants in Your Water?

Stop using your water and use bottled water for drinking, preparing food, or making ice if water tests show contaminants in your well water or if you suspect your well could be contaminated.

Follow these steps from Restoring Your Private Well:

  • Check the well and area around the well for damage.
  • Repair and flush your well.
  • Disinfect your well water to address biological contamination.
  • Test your water to assure suitable quality for all household uses.
  • Contact your area health department for help.

If you suspect your well is contaminated by gasoline or heating oil immediately contact your local health department and the DEC Spill Hotline at 800-457-7362.

Stop using your water until contamination is addressed and water tests confirm your water is suitable for household use. Boiling or disinfecting water will not remove oil and other chemicals in drinking water.
