Under the Water (Prevention and Control of Pollution) Act, 1974, every industry has to provide adequate treatment of its effluents before disposal, irrespective of whether it is in stream, land, sewerage system of sea. The small scale industrial units (SSI), which are presently defined as units whose plant and machinery are valued at less than Rs. 5 crore occupy an important place in the country's economy. The SSIs are a major contributor to the total industrial pollution load of the country. However, only a small fraction of the effluent discharge from these units is estimated to be treated as on date.

Water quality study and cost-benefit analysis of rainwater harvesting in Kuttanad, Kerala
The study reveals the urgency of water scarcity and sheds light on the potential remediation strategies. Posted on 25 Aug, 2011 02:23 PM

KuttanadThis thesis by Christina Tang for the Center of Environmental Studies, Brown University deals with a study of water quality and attempts to ascertain the net benefits or costs from rainwater harvesting under a variety of scenarios for households in various water supply conditions.

Eighty percent of the 7,00,000 citizens of Kuttanad, a region in the coastal State of Kerala have no access to clean water. In Kuttanad, intensive untreated human sewage and agricultural activities have caused severe surface water contaminations. At the same time, other sources of freshwater are unreliable for drinking: groundwater is acidic due to the soil conditions and iron leaching; freshwater from public tap is infrequent; and water supply from private vendors is extremely expensive.

Challenges of sustainable water quality management in rural India - Current Science
This paper published in the journal Current Science discusses the various factors that impact effective water quality management in rural India. Posted on 23 Aug, 2011 04:51 PM

FluorideThe 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.
