## 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.

## Workarounds

1. **Drink sealed bottled water, or water boiled for 1+ minute (3 minutes at altitude), or treated with a reliable filter/purifier.** (92% success)
   ```
   Buy sealed bottled water, boil, or use a certified filter/UV purifier; check that bottle seals are intact.
   ```
2. **Avoid ice of unknown origin and raw produce you did not peel or wash with safe water.** (85% success)
   ```
   Skip ice when unsure; eat fruit you peel yourself.
   ```

## Dead Ends

- **Drink straight from the tap or use tap ice because the place looks developed** — Visitors lack local immunity; tap water and untreated ice are common causes of traveler's diarrhea and more serious infections in Bangladesh. (60% fail)
- **Brush teeth or rinse raw salad with tap water** — Even small amounts of contaminated water - brushing teeth, rinsing produce, melting ice - can cause illness. (45% fail)
