Treatment and Purification

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.

This guidebook published by the Karnataka State Pollution Control Board takes the reader through various units, operations and processes in a typical Extended Aeration Biological treatment plant, the Workhorse of the industry.

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 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.

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.
