Professor says Water Advisory was Overblown

Ann Arbor, MI – A University of Michigan professor says public health officials who told residents to boil water for five minutes during the recent blackout to make it safe to drink are guilty of what he calls "terrorist acts on a stressed population."
Rolf Deininger says the tests used by cities to determine the safety of drinking water are antiquated, dating back to 1880's Germany.
Deininger is a professor of Environmental Health Sciences at the UofM's school of Public Health. He says one only needs to boil water for one to three minutes before it's safe to drink. He says you can also add eight drops of bleach to a gallon of water, and it'll be safe to drink after it sits for 30 minutes.
