What can people or municipalities who draw their water from a lake or stream that is to be treated do to avoid drinking rotenone treated water?
A. Normal treatment of water drawn from a lake or stream should remove or destroy any traces of rotenone. Charcoal filtration and chlorination would both protect users from exposure to any rotenone that might temporarily occur. Potassium permanganate could also be added to destroy any rotenone that might be present.
