Arsenic in groundwater beyond allowable concentration of 0.05 mg/lit in some parts of India, has posed serious threat to well being of large section of people. As one of the major mitigation, the contaminant is being removed from extracted groundwater and then the water is pressed for essential use of the people. There are several methods being employed for removal of arsenic in it's pentavalent as well as trivalent forms. The sludge generated from co-precipitated flocs or backwater water from absorbed/adsorbed/Ion exchangers etc.

The Barind Multipurpose Development Authority (BMDA) has been supplying arsenic-free drinking water among people in some parts of the dried tract for the last couple of years.
Sources said the BMDA has a target to construct 620 more installations to supply the safe drinking water through pipeline by the forthcoming June.
The initiative was taken to reduce the acute crisis of drinking water in the drought-prone Barind area especially during the dry season.

Quantification of natural groundwater recharge is a basic prerequisite for efficient groundwater resource management and is particularly vital in an area where shallow groundwater is mostly polluted with highly toxic elements. It is especially critical where large and concentrated demand for groundwater supplies exist such as in urban areas, industrial zones and irrigated fields.

Environmental exposure to arsenic has been linked to hypertension in persons living in arsenic-endemic areas. The researchers summarized published epidemiologic studies concerning arsenic exposure and hypertension or blood pressure (BP) measurements to evaluate the potential relationship.

NEW DELHI, May 7 – UNICEF has reported arsenic contamination in ground water in 18 districts of Assam and fluoride contamination in five districts.
Based on information from Chief Engineer (PHE) of the State Government, a UNICEF study has found arsenic and fluoride contamination, Minister of State for Water Resources, Vincent H Pala said in a Rajya Sabha reply to a question by Naznin Faruque.

Even though e-Waste (Management and Handling) Rules have come into force from Tuesday, the AP Pollution Control Board is still gearing up for implementation and strict enforcement of these rules with a framework of guidelines to be followed by manufacturers of e-products.

The Union ministry of environment and forests had announced e-waste rules way back in June 2011 under the Environment Protection Act. This would be implemented in letter and spirit only after the APPCB prepares a draft explaining “how to ensure implementation and check violation” of the norms.

Depletion of groundwater and its increasing pollution could be leading to a silent, nationwide public health crisis as aquifers in many stretches across India are becoming unfit for drinking, according to the government’s own figures.

Survey conducted by Pakistan Council of Research in Water Resources (PCRWR) has revealed out of as many as 239 Water Supply Schemes (WSSs) in district Attock, 25 % are supplying contaminated water which contains micro-organisms, arsenic, iron and hardness. Mostly untreated water is being supplied to the consumers, which is causing many waterborne diseases among adults as well as kids alike.

Sandwiched between India and Myanmar and with an area of 147,570 sq km, Bangladesh is among the world's most densely populated countries with a population of 164 million. The country is geologically part of the Bengal Basin, among the largest in the world. Nearly 50 per cent of the country lies at an elevation of less than 10 m above sea level, and only the southwestern parts of the country exceeds an altitude of 300 m above sea level.

Arsenic contamination of ground water from Yamuna floodplains in Delhi is several times the permissible limit and the prime culprit for this poisoning is fly ash and other residue from Delhi’s thermal power plants, a study by the Department of Geology at Delhi University (DU) has found. “Samples were collected from the Yamuna floodplains, one of the most important ground water recharging sources in the city, to study the level of arsenic content in it.
