Private Well and Drinking Water
If you live in an area that flooded, pollutants from floodwaters might contaminate your private well. If you think your drinking water is contaminated:
- Stop drinking it or using it for preparing food immediately.
- Switch to a safe water source such as a neighbor’s well you know is safe, a community water supply, or buy bottled water. If you can’t find a convenient source of safe water, boil your well water for one minute at a rolling boil before using it.
- Disinfect your well, or get your water tested to check for contamination.
- If your water tests positive for bacteria, your water is unsafe. Read Bacterial Contamination of Private Wells for more information. Do not use the water unless boiled at a rolling boil for at least one minute.
- If your water tests negative for bacteria, consider the water safe to drink but re-test in another month.
- Learn more about how to protect your well from contamination in the future.
