This presentation deals with the problem of arsenic contaminated aquifers in the Gangetic belt of Bihar and the failure of the state government in tackling the crisis and calls for the establishment of a centralized knowledge & research hub with an understanding of the regional peculiarities to mitigate the crisis.

It traces the origin of arsenic crisis to the switch from use of surface water to groundwater. The health impacts of arsenic poisoning and the factors that aggravate arsenicosis are explained. A total of sixteen districts (fifty-seven blocks) in Bihar are affected by high levels of arsenic in groundwater, in trivalent form, which is a more toxic form of arsenic.

The report of the Task Force appointed by the Planning Commission presents an action plan for removal of arsenic contamination in West Bengal. It looks at the extent of the problem, its intake sources, technologies available and the operation and maintenance (O&M) issues.

It outlines the diverse technologies based on various scientific principles, assesses them based on their scale of operation (domestic or community) on techno-economic considerations & infrastructure required and provides suggestions. Short, medium and long term measures are outlined for tackling the problem of arsenic contamination in drinking water supply in the state.

This manual produced by BIRD-K and DRDPR (GoK) provides the details of the Sachetana project that aims to provide safe drinking water to fluorosis affected populations through the adoption of innovative technologies for rainwater harvesting and groundwater recharge.

The project is being implemented through the Gram Panchayats of 60 villages from 4 taluks among three districts of Karnataka state over a period of five years (2006-11).

The objectives of the project include:

• Provision of safe drinking water through innovative rain harvesting structures
• Recharge of groundwater through excavation of percolation ponds
• Recharge of existing bore wells and direct recharge of aquifers
• Awareness generation activities to promote sustainable management and management of water resources and water harvesting structures.

Is there anyone in India who is willing to develop a multi-stage Saferain unit with me?
Imagine a 5000 sq metre factory in New Delhi, (or Shanghai, or wherever).

The air is polluted, the roof is polluted, and, yet, I say that potable. or near so, can be delivered in a rain event. The following is a cut and paste. This is how it's

For Immediate Release

Underwriters Laboratories Certifies Kimberlite Chemicals for Health Effects in Drinking water
Kimberlite Chemicals Becomes First Indian Company to Earn UL
Certification for Antiscalant Water Treatment Chemicals

Bangalore, India, April 14 2010 – Underwriters Laboratories (UL), a global leader in drinking water quality and safety, today announced that Kimberlite Chemicals India Pvt.  Ltd., received UL certification for its antiscalant water treatment chemicals. Kimberlite’s antiscalant water treatment chemicals will now bear the UL Classified Water Quality Mark, indicating certification to ANSI/NSF Standard 60 for health effects.

UL launched its drinking water product certification program in India in 2009 and has been working with a number of Indian companies on a broad range of products including disinfection and oxidation chemicals, coagulants, drinking water treatment units, gaskets, butterfly valves, sediment filter cartridges and activated carbon.  Kimberlite, a renowned company known for its world-class technology product and service in the field of specialty chemicals and coatings, is the first Indian manufacturer to be certified through UL’s water program for antiscalant water treatment chemicals.

UL’s certification of Kimberlite’s antiscalant chemicals provides verification that these chemicals have been independently tested and validated to meet both industry standards for health effects in drinking water as well as UL’s rigorous certification requirements. Antiscalant chemicals are used to protect reverse osmosis (RO) membrane life and are used in industrial RO purifiers.

Delhi, India

I, Gopi Dutt, want to draw your attention to problem that Delhi has been facing since as long as 10 yrs now. I am talking about the pollution in Yamuna caused by devotional material, Polybags, Flowers etc. Our govt., different NGOs and now Maharaja Sri Sri Ravi Shankar have put their best efforts to clean up the river. We all have been trying to clean it up for the past 10 yrs but it hasn’t stopped yet. Does anyone have a plan to stop this that here is no further need to clean n re-clean the river? The problem is that we only create awareness that people should not pollute the river but there are no measures taken to stop this pollution.

This research paper describes an indigenous water treatment method, that uses Moringa oleifera (Drumstick) seeds in the form of a water-soluble extract in suspension, resulting in an effective natural clarification agent for highly turbid and untreated pathogenic surface water.

This is the fourth in a decadal series of reports published by the Central Pollution Control Board (CPCB), previous ones published in 1978-79, 1989-90 and 2000, which provides basic information about the status of water supply and sewage generation and treatment of 498 Class-I cities and 410 Class-II towns, along with information on 53 coastal Class-I cities and 35 coastal Class-I towns, besides Ganga Basin as a separate subsection.
