Challenges of sustainable water quality management in rural India - Current Science
Posted on 23 Aug, 2011 04:51 PMThe article informs that access to safe drinking water remains an urgent necessity, as 30% of urban and 90% of rural households still depend completely on untreated surface or groundwater.
While access to drinking water in India has increased over the past decade, the tremendous adverse impact of unsafe water on health continues. It is estimated that about 21% of communicable diseases in India are water related.
Although some degree of intervention in terms of chlorination and monitoring of water quality exists in major cities and towns, rural India, which constitutes the bulk (70%) of the population, is usually deprived of such interventions. The population in rural India is mainly dependent on the groundwater as a source of drinking water. As a quality concern the groundwater is often found to be contaminated with fluoride, arsenic, iron and salts. In recent years, fluorosis has emerged as major public health issue in rural India.
Water quality status of rivers in India – Report of Central Water Commission
Posted on 15 Jul, 2011 06:19 PMThe Level-I Laboratories are located at 258 field water quality monitoring stations on various rivers of India where physical parameters such as temperature, colour, odour, specific conductivity, total dissolved solids, pH and dissolved oxygen of river water are observed.
Hi-tech vs low-tech in the water sector in the village of Dandiganahalli near Bangalore - Article by S. Vishwanath
Posted on 28 Jun, 2011 05:40 PMEver since Schumacher wrote his now very, very famous book small is there has in my mind been a question of the appropriateness of the solutions we urban educated types posit for rural ‘problems’.
Chemical characteristics responsible for the higher concentration of fluoride in groundwater - A paper in Springer Science
Posted on 21 Jun, 2011 01:42 PMFluoride is essential for normal bone growth, but its higher concentration in drinking water poses great health problems and fluorosis is common in many parts of India.
Multi-district assessment of water safety (M-DAWS) in Gujarat - A study by Water and Sanitation Management Organisation
Posted on 15 Jun, 2011 12:08 PMThis report by the Water and Sanitation Management Organisation (WASMO) is based on the analysis of Multi-District Assessment of Water Safety (M-DAWS) carried out in 8 districts of Gujarat (Vadodara,Valsad, Mehsana, Gandhinagar, Kachchh, Surat, Ahmedabad and Dangs) , where ensuring adequate and safe drinking water to the people has been looked upon as a huge challenge needing urgent action during years 2007 and 2008 .
The Multi-District Assessment of Water Safety (M-DAWS) programme was undertaken by Water and Sanitation Management Organisation (WASMO) with financial and technical support from UNICEF.

Flouride problem in Guttavarepalle village, Madanapalle, Andhra Pradesh - A field report by Arghyam and Outreach
Posted on 31 May, 2011 12:07 PM
Overview
It is surprising that fluoride was found even in surface water bodies like ponds, because fluoride is generally found in deep aquifers. Fluoride is a naturally occurring mineral in the deeper layers of rock beneath the earth's surface, so it was unusual to find it at such high levels even in surface water sources, leading to the conclusion that intensive agriculture in the area has spread the fluoride to the surface.
New research centre for applied groundwater research at the University of Guelph in Ontario Canada, dives into uncharted waters
Posted on 19 May, 2011 10:42 PMHow exactly do contaminants spread underground? How much urban stress can an aquifer withstand?
With the need for clean fresh water growing daily, finding answers to those questions is a top priority for researchers at G360, the new Centre for Applied Groundwater Research at the University of Guelph in Ontario, Canada.
The real picture of arsenic pollution in West Bengal, India
Posted on 17 May, 2011 11:34 AMArsenic poisoning in these districts is a serious environmental problem and is affecting the health of millions of people in the State. The problem has been aggravated with increase in groundwater exploitation leading to leaching of arsenic located in upper layers of sediment down into the deep aquifers.
During my visits to these districts, I have had dreary experiences -
Water quality in Penukonda region of Anantapur district - A field report by Arghyam
Posted on 16 May, 2011 06:23 PMIntroduction
SEDS approached Arghyam to seek advice on the quality of drinking water in the area. Anantpur is the second most drought-prone area in India, and a lot of work has been done to deal with the water supply situation by the Government of Andhra Pradesh as well as NGOs and charities such as SEDS and the Sai Baba Trust, to name a few. There seems to be an adequate supply of water in the district, but very little or no attention has been paid to the quality of water.
