Physicochemical assessment of water quality with respect to remote sensing and GIS techniques - Paper published in the journal Advances in Pure and Applied Chemistry
This paper published in the journal Advances in Pure and Applied Chemistry, sheds light on the serious problem of the increasing levels of pollution of water bodies in India due to escalating populations, urbanisation and increasing economic activity and highlights the urgent need to conduct effective and efficient water quality assessment measures. The paper highlights the limitations associated with the conventional water quality assessment methods and discusses the recent advances in Remote Sensing (RS) and Geographical Information System (GIS) techniques and their relevance as promising alternatives for effective water quality assessment to the conventional water quality assessment methods. Posted on 30 Apr, 2012 12:43 PM

The paper informs that current techniques normally used in the country for monitoring and assessment of the quality of water bodies involve in situ measurement and/or the collection of water samples for subsequent laboratory analysis of the chemical, physical and biological characteristics of water.

Depleting water resources in Thalassery, Kerala: Huge effort is required to address water supply and sewerage handling issues
By chance only I happened to see the IWP, and am very glad and impressed to see the efforts and dedication of the team involved, to help the nation to promote and achieve sustainable use of water. I wish I can also contribute to the portal in whatever way possible to serve this noble initiative, in order to be part spreading awareness and thereby ensuring excess to drinking water to our future generations.

A framework for rural drinking water quality management, based on experiences from the voluntary sector - A learning document by Arghyam
Arghyam, Bangalore, a non-profit foundation focusing on domestic water and sanitation, has published a document highlighting a water quality management (WQM) framework for rural areas. The framework lays out a phased and process-driven approach to WQM in rural areas and is based on work done by 12 prominent non-governmental organisations (NGOs) who have been working on water quality (WQ), from across the country. Ayan Biswas of Arghyam writes about this. Posted on 20 Apr, 2012 04:33 PM


The phases that have been identified for a sustainable WQM programme are: 

(1) Assessment of baseline situation

(2) Participatory planning

(3) Water quality monitoring

(4) Implementation

Assessment of physico-chemical quality of groundwater in rural area nearby Sagar city, Madhya Pradesh

This paper presents the results of forty groundwater samples collected from June 2007 to July 2010 in Gambhira and Baheria villages in Madhya Pradesh. The authors conclude that the ground water quality is degraded due to anthropogenic causes.

How valuable are environmental health interventions? - Evaluation of water and sanitation programmes in India - Paper published in the Bulletin of the World Health Organisation
This paper published in the Bulletin of the World Health Organisation presents the findings of a valuation study that estimated the economic value of the average “treatment effect” of a community demand driven water and sanitation programme. The study employed a unique combination of propensity-score “pre-matching” and large panel data to estimate the economic impacts of a multi-dimensional environmental health programme. Posted on 21 Feb, 2012 06:11 PM

The paper informs that a number of epidemiological studies on the benefits of water and sanitation interventions have shown that diarrhoea can be reduced by 30–50%.

A number of studies have made associations between prevention of disease burden among populations by improving water supply, sanitation, hygiene and management of water resources and between poor water quality and disease burden.

Impacts of climate change on public health in India - Future research directions - Paper published in Environmental Health Perspectives
This paper discusses the observed relationships between climate variability and human health. Posted on 19 Feb, 2012 11:00 PM

This paper published in the journal Environmental Health Perspectives reviews the current state of the science relevant to the 2009 Joint Indo–U.S. Workshop on Climate Change and Health that was held in Goa, India, and, then discusses the observed relationships between climate variability and human health specifically in relation to the Indian subcontinent, highlighting future research directions.

The paper briefly summarises relevant literature on the impacts of climate change in India and touches upon the opportunities and significant challenges associated with designing, initiating, and conducting research, as well as pursuing related public health programming to improve public health infrastructure in the face of climate change. The paper argues that such research is needed to pave the way for unique and pioneering solutions that can improve public health in the face of increasing climate variability.

Understanding governance in WASH sector in Andhra Pradesh - A study by WASSAN
The paper examines the issue of water governance- its key elements, applicability, and influence on service levels. Posted on 18 Feb, 2012 03:38 PM

Problems in the water, sanitation and hygiene (WASH) sector have their roots in socio-political issues rather than in technology. This paper presents the report of a survey in 107 villages in rural Andhra Pradesh to illustrate the influence of governance systems.
