The Ganga is the most sacred river in the sub-continent, and revered by millions.It is also among the top ten rivers at risk. The key threat to the river is indiscriminate abstraction of water from the river, leavng it unable to maintain its ecological integrity or to satisfy the needs of riparian communities.

Sarakki Lake, also known as Jagaranahalli Lake located in South Bangalore is one of the oldest lakes in Bangalore, and once upon a time one of the most glorious. It has now become a reservoir for untreated sewage and a dumping yard for the surrounding neighbourhoods. This lake was a source of water for four villages up until just a few years ago.

Effects of industrial and agricultural activities on properties of groundwater - A paper published in the Bulletin of Environment, Pharmacology & Life Sciences
This paper published in the journal Bulletin of Environment, Pharmacology & Life Sciences describes the findings of a study that was carried out to check the effects of industrial and agricultural activities on the groundwater properties in terms of heavy metal concentration. Polluted groundwater is defined as groundwater that has higher concentrations of dissolved or suspended elements than the maximum permissible concentrations fixed by national or international standards for drinking, industrial or agricultural purposes. Sometimes natural groundwater pollution may also occur because of the presence of the respective substances above the prescribed limits.

The main sources of groundwater contamination are industrial, municipal and agricultural wastes (both solid and liquid), rocks, sludge and slimes, refuse, pesticides, herbicides, effluents from livestock and poultry farms. Many pollutants are even able to penetrate into groundwater aquifers.
"Excreta Matters" - A profile of the water and sewage situation in 71 Indian cities - A report by the Centre for Science and Environment
The just released Citizens’ Seventh Report on the State of India’s Environment, “Excreta Matters: How urban India is soaking up water, polluting rivers and drowning in its own excreta” deals with where Indian urban centers get their water from and where their waste goes. The report by the Centre for Science and Environment (CSE) calls for using correct technology, planning for cost recovery and resource sustainability, building and renewing local water resources and designing sewage systems differently. It also calls for a law on the right to clean water.

People in National capital territory of Delhi are far away from safe drinking water: Role of governance and civil society
Dhobi Ghat, a slum area with a majority of Muslim population , is situated on the bank of river Yamuna, near Batla House, Jamia Nagar, New Delhi with around 150 families. These families are mostly deprived and poor, surviving with low literacy rate, malnutrition, hunger and lack of sanitation. This report by Ravi Nitesh deals with how people in Delhi do not have access to safe drinking water.

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.

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.

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
