What to do:
The most important thing is to stay safe.
If water is starting to flood your house, turn off all electricity to avoid electrocution, and have an electrician certify that the power can be turned on again when water has gone away. Do not drink water from groundwater wells or surface water if you are anywhere near flooded areas. If your septic tank is flooded, do not flush your toilet, until water has gone back to normal levels.
Please do not visit the flooded streets. You can best help by filling sandbags to protect houses or by helping clean up streets and shorelines from debris when the water has receded.
If you spot pollution or see something that doesn’t look right on the river, you can report it to our Pollution Hotline at 1-888-953-3737 or online.
