Figure 7. Map of the average arsenic concentration (mg/L) in water from tubewells less than 30.5 m (100 feet) bgs.
Figure 10. Map of the average sulfate concentration (mg/L) in water from tubewells less than 30.5 m (100 feet) bgs.
Moreover, the concentrations of arsenic and sulfate are not correlated (see Figures 7 and 10).
In addition, the relatively poor correlation between arsenic and total sulfur (r = -0.08) observed during our second national-scale survey in 1998-1999 supports this 1997
hypothesis that pyrites are not the principal source of arsenic in Bangladesh’s groundwater.
Therefore, Hypothesis #1 is not generally correct so the use of groundwater for irrigation should NOT be stopped in this famine-prone country.
