Read MoreWater quality hot-spots in rivers of India – A report by Central Water Commission
This report by the Central Water Commission (CWC) attempts to provide the water quality scenario of our rivers and evolve a methodology for identifying hot spots in Indian rivers. The water quality data is based on the average values observed during the last ten years (2001-2011) at 371 monitoring stations of CWC on almost all major, medium and minor rivers in India. In respect of Dissolved Oxygen and Biochemical Oxygen Demand, the Central Pollution Control Board's classification has been considered for evaluating the hot spot in the rivers.
The physical and chemical quality of river water is important in deciding its suitability for drinking purposes. As such the suitability of river water for potable uses with regard to its chemical quality has to be deciphered and defined on the basis of the some vital characteristics of the water. Bureau of Indian Standards (BIS) vide its document IS: 10500:1991, edition 2.2 (2003‐09) has recommended the quality standards for drinking water and these have been used for finding the suitability of river water. On this basis of classification, the natural river water of India has been categorized as desirable, permissible and unfit for human consumption.

Read MoreIndia’s groundwater challenge and the way forward - Economic and Political Weekly
This paper published in the Economic and Political Weekly highlights the present groundwater situation in the country and warns that groundwater quantity as well as quality are the two major problems that the country has been facing.
The rate of withdrawal of groundwater has reached “unsafe” levels in 31% of the districts, covering 33% of the land area and 35% of the population. The situation has dramatically worsened within a short span of nine years, between the assessments done in 1995 and 2004.
Taking the quantitative and qualitative aspects together, data indicates that a total of 347 districts (59% of all districts in India) are vulnerable in terms of safe drinking water in India. This is a matter of serious concern, requiring a new approach. Read More
Restoration of traditional small water bodies in Braj - The South Asian Journal of Tourism and Heritage
This paper published in the South Asian Journal of Tourism and Heritage begins by highlighting the importance of the traditional small water bodies in Braj, commonly known as kunds, as important freshwater sources as well as an important part of the culture and the traditions of the area.
There were 1000 such kunds, which used to be the source of fresh water in Braj in earlier times. The water was used for multiple purposes like irrigated agriculture, domestic uses, drinking water for cattle, bathing etc. Due to rapid urbanisation, lack of maintenance and prolonged negligence in the last 50-100 years, most of the kunds today have become silted up and are nearing extinction.
The impending crisis for fresh water has forced the planners and policy makers to take cognizance of these traditional water bodies and an urgent need has been identified for taking necessary measures to restore the kunds. The present study thus aims at understanding the reasons for deterioration of the kunds and makes some technical suggestions for revival of these kunds. Read More
