The situation is very bad. It seems that water in the area is contaminated due to algae in the area, mostly in Lake Erie, which releases a toxin called microcystin when it decays. The algae grows best in warm, shallow waters like those of Lake Erie. It can’t be boiled, boiling only concentrates the toxin. What about filters? Even filters such as Berkey filters have their limitations. They are capable of filtering pathogens and microorganisms, but getting rid of a cyanotoxins is a different story. The way I would deal with the situation would be this: I’d drink the water...
