Groundwater Pollution

This report by the Department of Mines and Geology describes the findings of a study on urban groundwater hydrology and groundwater quality in and around Bangalore city. Earlier studies carried out by the Department of Mines and Geology during 1994, 1995 and 2003 on the groundwater quality of Bangalore Metropolis had found that the groundwater pollution in the city has mainly been due to sewage disposal and recommendations have been made to prevent pollution from sewage and industrial wastes. The supply of the required quantity of water to the population continues to remain a big challenge to the concerned authorities in Bangalore.Read More

The reports titled 'Status of groundwater quality in India (Part I and Part II) present the results of a detailed survey of groundwater quality in metropolitan areas (population >100,000) in India. The report recognises that most groundwater quality problems are anthropogenic in origin, caused by a combination of over-exploitation and infiltration of wastes. Inadequate infrastructure and resources mean that waste generated by cities and industrial areas is not properly collected, treated and disposed, thus leading to grondwater contamination.Read More

This document is a report of the workshop organised by Indo-Global Social Service Society (IGSSS) and Welthungerhilfe on the demonstration cum dissemination of the feasibility of KAF (Kanchan Arsenic Filter) in Assam. The workshop aimed at possible replication and acceptability of KAF as a viable, low cost appropriate arsenic mitigation measure in the arsenic contaminated regions of the country.Read More

This study by Greenpeace India Society is an initial investigation into the effects of synthetic nitrogen fertilizer on groundwater pollution in intensive agriculture areas in Punjab. The level of nitrate in drinking water was tested from groundwater artesian wells located within farms and surrounded by crops (mostly rice and wheat rotations).

Nitrate pollution in groundwater is associated with nitrogen loads in the environment. In urban areas, it is associated with sewage and in agriculture areas, with livestock sources and nitrogen fertiliser inputs. Nitrate pollution in drinking water can have serious health impact on humans, especially for babies and children. The most significant potential health effects of drinking water contaminated with nitrate are the blue-baby syndrome (methemoglobinemia) and cancer.
