Chemistry of groundwater – A presentation by ACWADAM
Quality of water is quintessential. Quality of groundwater supply determines where and for what it can be used. Posted on 21 Sep, 2010 10:40 PM

This presentation by ACWADAM deals with the chemistry of groundwater. It is now recognized that the quality of groundwater is as important as its quantity. All groundwater contains salts in solution which are derived from the location and the movement of water through rocks. The quality of groundwater supply depends where and for what it is planned to be used. Thus water quality standards for drinking water, industrial water and irrigation water differ significantly.

48% industrial clusters in India are critically polluted: CPCB
CPCB's comprehensive environmental assessment of industrial clusters finds only 16% spots with normal pollution levels. Ankleshwar in Gujarat is the worst, while Digboi in Assam is the best. Posted on 10 Aug, 2010 11:38 PM

CPCB ReportA Comprehensive Environmental Pollution Index (CEPI) is a very useful tool to capture the health dimensions of the environment including air, water and land. The CEPI is intended to act as an early warning tool and can help in categorising the industrial clusters/areas in terms of priority of planning needs for interventions.

This report by the Central Pollution and Control Board (CPCB) presents the results of the application of the CEPI to selected industrial clusters or areas.

The main objective of the study was to identify polluted industrial clusters or areas in order to take concerted action and to centrally monitor them at the national level. This was in order to improve the current status of environmental components such as air and water quality data, ecological damage, and visual environmental conditions.

Rapid assessment survey of Kodaikanal lake - ENVIS Centre (TN) (2009)
Tourists endanger Kodaikanal's freshwater lake and the biodiversity dependent on it Posted on 02 Aug, 2010 02:02 AM

Rapid Assessment survey of Kodaikanal lake - ENVIS Centre (TN)This document by the Department of Environment, Government of Tamil Nadu highlights the importance of the Kodaikanal lake as an important tourist destination and warns that this freshwater lake is under the threat of getting polluted and its biodiversity endangered.

The document presents the findings of the study that aimed at assessing the physico-chemical and biological quality of the Kodaikanal lake.

Evidence indicates that unrestricted tourism activities have led to high use of plastic bottles, glass bottles, plastic bags, causing high levels of pollution and silting of the lake. Damaged fibreglass boats left inside the lakes also pose a serious threat to the lake ecosystem.

Dr. G. D. Agrawal , the scientist, environmentalist and rishi
Dr. Agarwal - an Inspiring teacher, a humble man and the most-sought-after environmentalist Posted on 27 Jul, 2010 03:52 PM

Dr. G. D. Agrawal Scientist and Rishi

Meeting Dr. G. D. Agrawal in his spartan, two room cottage in Chitrakoot, Madhya Pradesh, you would never guess what an accomplished and distinguished scientist he is – first Member-Secretary of the Government of India’s Central Pollution Control Board, former Head of the Department of Civil and Environmental Engineering at IIT Kanpur and a PhD from the University of California, Berkeley. The list goes on and on.

Yet this eminent professional sweeps his own floors, washes his own clothes and cooks his own meals. He retains only a few possessions and dresses in homespun khadi. At the age of 76, his main mode of transport within Chitrakoot is a bicycle and when he travels further afield, he goes by ordinary bus and second-class train. These are the deliberate choices of a devout Hindu whose deepest values are for simplicity and reverence for nature. Dr G.D. Agrawal is the doyen of environmental engineering professionals in India. Well past retirement, he continues to teach and inspire students as an Honorary Professor of Environmental Sciences at the Mahatma Gandhi Chitrakoot Gramodaya Vishwavidyalaya, in Chitrakoot (M.P.).
