Chemical Pollution

The issue was examined by CAG because various stakeholders working in the field of environment flagged water pollution as the most important environmental issue that concerns us. 

The audit was conducted through document analysis, collection of responses to questionnaires, physical collection and testing of samples. The results of audit, both at the Central level and the State level, were taken into account for arriving at audit conclusions.

Following media reports about arsenic contamination in Ballia, and a complaint addressed by the people of Ballia to the Ministry of Rural Development, a National Level Monitor was requested to enquire into the issue of water quality.

The public art outreach project was organized by the Max Mueller Bhavan in association with the Government of Delhi and the Goethe-Institut (Hamburg, Germany) as a part of the “Year of Germany in India” programme opened on 5^th of November, 2011. The art exhibition which continued till the 19^th of November co-curated by artist Ravi Agarwal who is also a practicing environmentalist (Director, Toxics Link) along with German artist, Till Krauser attempted to create a pulsating synergy between the Yamuna and Elbe rivers.

The Central Water Commission (CWC) has recently prepared a report on water quality scenario of our rivers and has evolved 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. Please find below a letter (dated November 5, 2011) from South Asia Network on Dams, Rivers & People, New Delhi to the Chairman, Central Water Commission stating its concerns regarding the report.

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.

On the contentious policy relating to privatization of lakes, the Justice N K Patil Committee appointed by the Karnataka High Court has recommended that private sector participation solely based on commercial interest is not desirable.

In a significant development, the Committee appointed under the Chairmanship of Justice Mr. N. K. Patil, Judge of the Karnataka High Court and Chairman High Court Legal Services Committee, in response to the Public Interest Litigation by Environment Support Group challenging the privatisation of management and rehabilitation of lakes in Bangalore (WP 817/2008), has strongly recommended that ““private sector participation solely based on consequential commercial interest” is not a desirable model” (Emphasis in original).

This document  by the Central Pollution and Control Board (CPCB) describes the findings of a study that evaluated water treatment plants located across the country, for prevailing raw water quality, water treatment technologies, operational practices, chemical consumptio

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.

It evolves 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.
