Root Cause
Tap water in Bangladesh is generally not safe for visitors to drink. Tap and shallow groundwater can carry pathogens and, in places, arsenic; bottled or boiled water is the norm. Use sealed bottled water, or water boiled or properly filtered/treated, and avoid ice of unknown origin and raw produce washed in tap water.
genericWorkarounds
-
92% success Drink sealed bottled water, or water boiled for 1+ minute (3 minutes at altitude), or treated with a reliable filter/purifier.
Buy sealed bottled water, boil, or use a certified filter/UV purifier; check that bottle seals are intact.

85% success Avoid ice of unknown origin and raw produce you did not peel or wash with safe water.
Skip ice when unsure; eat fruit you peel yourself.
Dead Ends
Common approaches that don't work:
-
Drink straight from the tap or use tap ice because the place looks developed
60% fail
Visitors lack local immunity; tap water and untreated ice are common causes of traveler's diarrhea and more serious infections in Bangladesh.
-
Brush teeth or rinse raw salad with tap water
45% fail
Even small amounts of contaminated water - brushing teeth, rinsing produce, melting ice - can cause illness.
