Contamination, Pollution and Quality

This presentation by Sekhar Raghavan, Director, Rain Centre, Chennai, India highlights the experiences and the challenges faced by Rain Centre in introducing ecological sanitation in the coastal town of Kovalam near Chennai, Tamil Nadu, India along with Coastal and Rural development Trust (CRDT), a small non profit centre based in Kovalam .

The coastal town of Kovalam was selected as a case because of its peculiar situation with its location in a fast developing  peri-urban area in proximity to Chennai city characterised by good groundwater situation, adequate land and housing facilities, but with a glaring and urgent need and demand for toilets.

It does this in light of the recommendations of the Anwarul Hoda Committee, a High Level Committee set up by the Planning Commission in 2005. The draft SDF prepared by ERM India Pvt. Ltd. for the Ministry of Mines was released recently for seeking public comments before its formal adoption. It presents a set of guiding principles for the mining sector in India, which aims at achieving resource efficiency, business viability and environment stewardship around development of affected communities.

This document  on the Ministry of Environment and Forests site includes the Plastic Waste (Management and Handling) Rules replaces the earlier Recycled Plastics Manufacture and Usage Rules,1999 (amended in 2003).

This global study attempts systematically to understand and thus help practitioners manage the political economy of pro-poor sani­tation investments and service provision.

It aims to provide practical advice to multi-lateral agencies and sanitation practitioners to help them better manage stakehol­der relations and effectively maneuver within the complex institutional relationships of the sanitation sector in order to enhance the design, implementation, and effectiveness of operations that provide pro-poor sanitation investments and services. The ultimate goal is to improve health and hygiene outcomes.

This study follows current approaches to political economy - interdisciplinary inquiry drawing upon social and political theory and economic principles - to understand how poli­tical actors, institutions, and economic processes influence each other. This study’s conceptual framework combines a diagnostic component with a typology of actions to help translate analytical findings into more effective support to operations and investments.

This document by the Department of Drinking Water and Sanitation deals with the guidelines of the Central Rural Sanitation Programme (CRSP) and Total Sanitation Campaign (TSC). India’s first nationwide programme of rural sanitation, the CRSP was launched in 1986, while TSC was launched in 1999 with the aim of ending open defecation.

India and China account for one third of the world’s population; each consumes more freshwater than other nations. Per inhabitant per year, though, India uses less than half what’s used in the US, China uses less than one third. This YaleGlobal series examines India and China’s water use, their expectations for rising demand and recognition that shortages will disrupt economic progress.

The Planning Commission of India repeatedly warns that water will become a more serious issue than land or energy for India in years to come, points out Rohini Nilekani, in the second article of the series. India’s transition from an economy based on agriculture to a mixed one, with water use controlled by states rather than the federal constitution, already leads to conflicts. She urges planning for a low-water economy. Good governance and regulatory frameworks can prevent pollution and waste, while encouraging efficiency, reliable and fair allocation, and wise consumer choices.

Thirsty earth: Indian villagers in Gujarat gather to draw water from a well

The study of the hydrochemistry of the Manasbal lake was done to find out whether the lake water was fit for drinking, irrigation and other purposes.

This document by the World Health Organisation, for the first time, sets forth global criteria to evaluate whether a household water treatment option reduces waterborne pathogens sufficiently to protect health. Through use of a risk-based framework and by emphasizing the philosophy of incremental improvement, it is intended to provide implementers and policy-makers with an evidence-based and pragmatic approach to select options suited to local conditions.

Household water treatment interventions may play an important role in protecting public health where existing water sources, including those delivered via a piped network or other improved sources, are untreated, are not treated properly or become contaminated during distribution or storage. Household water treatment applications are a range of technologies, devices or methods employed for the purposes of treating water at the household level or at the point of use in other settings, such as schools, health-care facilities and other community locations. Point-of-use water treatment is another term used for household water treatment.

About 74 per cent of India's total population, currently about 1.25 billion, live in rural areas. More than one third of the water available to them is not potable. In a grim reminder that poor quality of drinking water leads to serious health problems, India has admitted that about 180,000 rural populated areas are afflicted by diseases which are caused due to impure, toxic organic and inorganic substances including tri-halo methane, chlorine, etc. Some states have reported multiple contaminations in drinking water and there is no doubt that the current water situation in India will get much, much worse unless suitable solutions are sought. Most existing purification methods not only remove the impurities but drain out the essential minerals as well. Moreover, they are expensive and require extensive maintenance. Thus a natural filter comprising of bamboo, gravel, pebble and other locally available natural adsorbents is a great alternative to carry out water purification. What makes this filter unique is the use of bamboo charcoal which is not commonly used in any filter designed for domestic purposes.
