Don’t trust bottled water. Reports of locals filling bottles with tap water, sealing and then selling as purified water have come out of several countries. Since Aquatabs have no unpleasant taste or colour, play it safe any time you are faced with suspect water. If you're visiting or living in an area with poor sanitation, be especially wary of the water. If your local Medical Officer of Health has issued a Boil Water Advisory for your community, take the advice seriously. Do not drink untreated water from a spring, stream, river, lake, pond or shallow well. Assume it is contaminated with animal, bird and/or human feces. Disinfect with Aquatabs or boil for 1 to 5 minutes depending on elevation. Prevention is easier than seeking medical treatment once infected. Aquatabs produce no unpleasant taste or colour and are safe and simple to use. If you run out of Aquatabs, boil all suspect water for 1 to 5 minutes depending on elevation.
