IN WHAT MAY help the civil society in overcoming the water-related problems, the Defence Research Laboratory has created a unique water treatment plant that can bring down the excessive arsenic, floride and iron content of the ground water to an acceptable limit.

Groundwater contaminated with arsenic imposes a big challenge to human health worldwide. Using natural compounds to subvert the detrimental effects of arsenic represents an attractive strategy. The transcription factor nuclear factor erythroid 2-related factor 2 (Nrf2) is a critical regulator of the cellular antioxidant response and xenobiotic metabolism. Recently, activation of the Nrf2 signaling pathway has been reported to confer protection against arsenic-induced toxicity in a cell culture model.

Availability of potable water under emergency situations like flood will soon be a reality.
For researchers of the Geo-Environment Division of the National Environmental Engineering Research Institute (NEERI) have come up with a water filter for such purposes.
The water filter, called NEERI-ZAR and designed by Mr Subhash Andey, Mr Prakash Kalker and Mr Madan Nanoti has already received the Nina Saxena Excellence in Technology Award at the IIT-Kharagpur this year.

As demand for freshwater soars, planetary supplies are becoming unpredictable. Existing technologies could avert a global water crisis, but they must be implemented soon.

The raw water quality available in India varies significantly, resulting in modifications to the conventional water treatment scheme consisting of aeration, chemical coagulation, flocculation, sedimentation, filtration and disinfection. The backwash water and sludge generation from water treatment plants are of environment concern in terms of disposal.

The International Committee of the Red Cross (ICRC) has announced closure of its water supply programme initiated by it in Azad Jammu and Kashmir in response to the October 2005 earthquake.

According to a handout released here on Thursday, the agency had rehabilitated and reconstructed over 40 rural water supply systems, involving rehabilitation and installation of over 600 kilometres of pipeline, in Muzaffarabad district in cooperation with the communities concerned after the devastating earthquake.

CHANDIGARH: The Haryana Government on Wednesday signed a memorandum of understanding with the Hyderabad-based Naandi Foundation to implement a pilot project on community safe drinking water systems in select villages in the State in a phased manner.

The MoU was signed by Haryana Commissioner and Secretary, Public Works Department (Water Supply and Sanitation) Roshan Lal and National Director (Water Programme) Amit Jain on behalf of Naandi Foundation in the presence of Chief Minister Bhupinder Singh Hooda and Water Supply and Sanitation Minister Randeep Singh Surjewala here.

Despite tall claims by producers of water purifiers, most of them fail to ensure safe drinking water for the household.

Our drinking water is supposed to deliver essential nutrients and minerals needed for healthy life. It should help maintain acidic levels in our body and natural streams must provide antioxidants. Finally, it should be free of all contaminants. But more often than not, water supplied to us has exactly the opposite characteristics.

HYDERABAD: All but reduced to cesspools, restoration of polluted, filth-ridden lakes, ponds and wells has always been a challenging, time-consuming and expensive process.

Not anymore, as a novel German technique promises to make the clean-up process a little bit easy.

A German group, Lavaris Lake, has come up with a

Nature knows better how to keep the water sources clean and nourishing. Our traditions, also could maintain their water sources for the past 10,000 years. Water quality problems and water scarcity- both are due to pollution of air, caused by increase in the use of fossil fuels. This produces rain with nitrates and acidity. This pollutes the surface water bodies and also the groundwater.
