I live on a lake (impoundment on the Raisin river actually)
I wouldn’t want to drink the water but I have used it to wash dishes and flush toilets. In a pinch I could boil it and drink it but I always have bottled water on hand.
I live up here in MA. We have a good ceramic hand filter for emergencies and a gallon of bleach. If it happens here, we won’t be able to bathe, but we will find a way to have water to drink if we run out of bottled water.
Need to do better on food, though.
No laughing matter up in Vermont. I poked fun at New York for closing all the Starbucks, but up there in VT those folks are undergoing a real trial.
