plan 556Arsenic Safe Drinking Water: Nadia -Set 8C (10)

Summary

Sustainable, community-based mitigation program that provides safe water through bi-tech wells (also known as ‘bore-dugwells’), and conducts public education on water-related health issues and personal hygiene practices.

Background

In India, more than 100 million people of the Ganges-Meghna-Brahmaputra belt are at risk of arsenic poisoning. Five states are facing this crisis; in West Bengal alone, more than six million people are drinking crystal clear but arsenic-contaminated water from private and community tubewells. Epidemiological studies show that 1 in 100 people would die if exposed to an arsenic concentration of 0.05 mg/L in drinking water, and 1 in 50 would die if exposed to 0.1 mg/L (a common arsenic level in the private tubewells of many villages in West Bengal). Since 2001, Project Well has been providing arsenic-safe water to the rural communities by constructing shallow dugwells that tap water from unconfined aquifers that contains no arsenic. Since then, after extensive observation and research, we have modified the design to a bore-cum-dugwell that we have named bi-tech well—these improved wells are able to provide water all throughout the year. We have also implemented a Follow-Up/Surveillance Program, through which regular monitoring and evaluation of the utility of these bi-tech wells is done so that the community-based programs become sustainable. A chlorine-based disinfectant called ‘Theoline’ is administered weekly to control the growth of bacteria. No reports of diarrheal diseases have been received from the beneficiaries during the monthly field visits. Earthen, or ‘mawtka’, filters are used by villagers to remove any odor or turbidity that might be present due to the iron or other impurities. More than 7000 people use water from these wells. Over the past decade, through the surveillance program we could assess that 25% of the wells have been closed; most of the closed wells were constructed during the first few years of the program. The reasons for closure are usually technical faults, unsuitable site selection, non-cooperation from locals or panchayet, and lack of outreach programs. For the past four years, after a revision in the design of the well and an intensification of the awareness programs, demand for Project Well bi-tech wells has increased.
