Figure 7. Map of the average arsenic concentration (mg/L) in water from tubewells less than 30.5 m (100 feet) below ground surface (bgs, · = village location).
Approximately 50% of the aerial extent of Bangladesh contains groundwater from shallow tubewells (< 30.5 m or < 100 feet bgs) with an average arsenic concentration
greater than the national drinking water standard (0.05 mg/L).
This wide-spread distribution suggests the dominant source of arsenic is one or more geologically deposited minerals.
