PRIVATE WELL-OWNERS
If you’re unsure if your well has been impacted by flooding, you should assume it’s been contaminated.
Signs that a well may be affected by a flood include:
Floodwaters that came into contact or ran over the top of a well.
Noticeable changes in the taste, smell, or color of the water.
Use safe water for drinking, food preparation, and personal hygiene until your well water is tested and found to be free of bacteria. Safe water is:
1) Bottled water
2) Tap water that has been boiled for one minute
3) Water from an uncontaminated well
To ensure safety, test private well water for bacteria. Test kits are available through Waukesha County’s Environmental Health Division.
Get Well Water Tested: Order a test kit here: https://www.waukeshacounty.gov/.../private-well-water.../
MUNICIPAL WATER USERS:
Contact your local water utility regarding water safety concerns; follow any instructions provided.
Run water faucets for at least five minutes before using water for drinking or food preparation.
Always wash your hands with soap and water that has been boiled or disinfected before preparing or eating food and after using a toilet, participating in flood clean-up activities, and handling articles contaminated with flood water or sewage.
Keep open cuts or sores that have been exposed to flood water clean by washing the affected area with soap to control the infection. If a wound develops redness, swelling, or drainage, seek immediate medical attention.
Action to Take with Food After A Flood
Baby formula:
- Use only prepared, canned baby formula that requires no added water.
Food not in waterproof containers:
- Discard if they have come into contact with floodwater.
Canned foods:
