Arsenic pollution in groundwater in West Bengal – A research report by National Institute of Hydrology
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. Posted on 28 Jun, 2010 09:08 PM

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.

Arsenic contamination of groundwater in Bihar and mitigation strategies - A research study
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. Posted on 12 May, 2010 11:24 PM

Arsenic contamination of groundwater of Bihar and mitigation strategies - Map 2009This 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.

Formulating action plan for removal of arsenic contamination in West Bengal - Planning Commission Task Force report
This report of the Task Force appointed by the Planning Commission presents an action plan for removal of arsenic contamination in West Bengal. Posted on 12 May, 2010 11:49 AM

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.

A mid-term assessment - Sachetana drinking water plus project - Fluorosis Mitigation - BIRD-K - Mundargi taluk - Gadag district (Karnataka)
A report assessing the Sachetana Drinking Water Plus project in 3 districts of Karnataka that was implemented for fluorosis mitigation Posted on 29 Jan, 2010 06:02 PM

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.
