Observed HDI for the block Nawda ranges from 0.4 to 0.6 for both actual and arsenic pollution affected HDI. There was
negligible impact of arsenic pollution on HDI (Figs. 3a and 3b) as arsenic concentration in groundwater of this block was low (0 to 0.15 mg/L). HDI of block Raghunathganj-2 was affected by arsenic pollution as the areal coverage of HDI range 0.4 to 0.5 was reduced and came under the range of 0.3 to 0.4 (Figs. 4a and4b).
