Geogenic Contamination

Had the opportunity to attend a recent worldwide gathering on the topic of youth and social entrepreneurship, which gave much food for thought. The event was the 5th Global YES Summit, entitled “ReWork The World”.  Details of the gathering are at www.reworktheworld.org . The message there  was that we need to do something radical in order to find productive work for the vast numbers of youth coming into the workforce especially in developing nations. The new jobs cannot be of the old variety, they need to be green, sustainable jobs. In other words, we need to ‘rework the world’.  The conference was based on the premise that these new jobs will come out of social entrepreneurship.

The fluorosis section of this website dedicated to Nalgonda district, highlights the acute problem of very high levels of fluoride in the ground water resources of the district and its impact on the health of people - a high prevalence of severe and crippling bone and skeletal deformities. The site has information on the status of the affected people, flouride levels and various articles, petitions and pictures.

The report describes the results of the study of arsenic pollution in groundwater in Nadia as well as the hydro-chemical study of the river Hoogly in West Bengal. The alluvial tract along the river Hoogly covering a stretch of around 470 km encompassing eight districts is affected by arsenic pollution of ground water, the source being geogenic.

This presentation deals with the problem of arsenic contaminated aquifers in the Gangetic belt of Bihar and the failure of the state government in tackling the crisis and calls for the establishment of a centralized knowledge & research hub with an understanding of the regional peculiarities to mitigate the crisis.

It traces the origin of arsenic crisis to the switch from use of surface water to groundwater. The health impacts of arsenic poisoning and the factors that aggravate arsenicosis are explained. A total of sixteen districts (fifty-seven blocks) in Bihar are affected by high levels of arsenic in groundwater, in trivalent form, which is a more toxic form of arsenic.

The report of the Task Force appointed by the Planning Commission presents an action plan for removal of arsenic contamination in West Bengal. It looks at the extent of the problem, its intake sources, technologies available and the operation and maintenance (O&M) issues.

It outlines the diverse technologies based on various scientific principles, assesses them based on their scale of operation (domestic or community) on techno-economic considerations & infrastructure required and provides suggestions. Short, medium and long term measures are outlined for tackling the problem of arsenic contamination in drinking water supply in the state.

The Sachetana Drinking Water Plus project implemented by the BAIF Institute of Rural Development (BIRD-K), in three districts of Karnataka, aims to solve the problem of endemic fluorosis in the region, by providing an alternate source of water and by improving the quality of groundwater.

This report is a mid-term assessment of the project in Mundargi taluk of Gadag district of Karnataka, undertaken to understand and document the decentralized fluoride mitigation strategy adopted in the project villages and to analyze the impact on the groundwater levels and water quality as a result of the project's efforts.

This work won the CII-GBC National Award (Beyond the Fence Category) for Excellence in Water Management in 2008.
