Counting the cost of water pollution : an investigation into arsenic poisoning in West Bengal

Abstract

Arsenic contamination affects drinking water in almost half of the districts of West Bengal in India. This in turn has a significant impact on the health of many people in the area. In an attempt to find a solution to this health crisis, a SANDEE study examined the costs of contamination and its implications. It finds that households would benefit to the extent of Rs. 297($7) per month if arsenic concentrations met safety standards. The current cost of supplying safe piped water by the Kolkata Municipal Corporation is Rs 127 ($3) per month per household. Thus, investing in safe drinking water is economically feasible. The study also finds that poor households, who are most affected by the pollutant, will be major beneficiaries of any such solution.
