Flood waters can carry many contaminants that can harm your health, such as sewage, fertilizer, manure, gas, and pesticides. It is important to stay out of flood waters if possible and clean up properly.
If you live in an area that flooded, your private well might be contaminated by pollutants from the floodwaters. 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.
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.
