Summary
Self-supporting community- based mitigation program that provides arsenic safe water using modified dugwells along with public education on water related health effects.
Background
Project Well, PW, (2001) has developed a self-supporting community-based mitigation program to provide arsenic safe water to the villagers of the districts of N 24 Parganas of West Bengal, India. There are 22 blocks in this district. PW has been operating in the parts of the blocks namely, Deganga and Habra, where the population drinking arsenic contaminated water >50µg/L are 87,334 and 66,685 respectively, and drinking >10 µg/L are 133460 and 106374 respectively (In India the drinking water standard for arsenic, according to the Bureau of Indian Standard, is 10µg/L). Experts from various disciplines are advisors of this program. The primary objective of Project Well is to encourage the use of modified conventional dugwell through small community-based groups, comprising 10-20 families, to manage the new source of arsenic safe water and make it sustainable.The program began with the first dugwell in 2001. The outcome of the one-year research program was published in 2003 (Ref: Smith, M. M., T. Hore, et al. "A dugwell program to provide arsenic-safe water in West Bengal, India: preliminary results." J Environ Sci Health Part A Tox Hazard Subst Environ Eng 38(1): 289-99, see pdf file below). In total, 45 dugwells were constructed in different villages. The map of the target area with the location of the dugwells is available at http://projectwellusa.org/maps/maps.htm. The villages under the Kolsur panchayat have been reported to be severely affected, with 75% of their tubewells contaminated.. In the next two years forty dugwells will be introduced in the Gaighata block where the number of people drinking water containing arsenic >50 µg/L is estimated to be about 106,000, and those who are drinking >10 µg/L number about 155,000.
