we have the brain eating amoeba in our eater here... is been here for decades started here as green turle disease , that kids would get from catching turtles in ditches .. it kills in hours instead of days.. so we have & keep a large amount of chlorine levels for safety.. if they cut that level down the amobea will kill kids quickly & folks will notice right away.. but just incase.. BOIL YOUR WATER & stash it, is the best way.. when water main pipes leak or break here , we get boil water alerts almost regularly .. boil is the only sure way
