Green pastures and meadows, tall trees, lakes, wells and the river…those are my memories of Delhi. It wasn’t too long ago that one woke up early to the sounds of lawns being watered, children running off to school and people walking in the parks. A flurry of activity but quite different from what it is today.

River water quality data by Central Pollution Control Board (2005)
Rivers are one of the prime suppliers of drinking water. They are also important for agriculture, fisheries and recreational activities. However some of these activities also pollute the rivers. Pollution can be either from point sources such as industrial or sewage effluent discharges, or can be diffused from roads or agricultural run-off. Therefore it is necessary that rivers are protected from pollution and are managed as a sustainable resource for all of the activities that depend on their water quality.

Groundwater contamination is a serious, but relatively ignored issue in the country. This contamination occurs in either through geogenic or anthropogenic means. Fluoride contamination is one such example of geogenic contamination that is widely found in the Kolar district of Karnataka. However, the fluoride levels in the town of Mulbagal are lower than those in the surroundings. Earlier, a study was conducted on the impact of pit toilets on the groundwater in the area. The present paper investigates the presence of any link between these two phenomena.View of Mulbagal Town, Kolar District, Karnataka

Given the many problems associated with flush toilets and the sewerage system, pit toilets offer a viable solution in India. However, the use of soakpits raises the question of groundwater contamination. This paper assesses the impact of pit toilet leachate on groundwater quality in Mulbagal town (pop ~ 60,000) in Karnataka relies on pit toilets, and uses groundwater for drinking.View of the town of Mulbagal, Karnataka
