In Guj, water uranium level highest in Ahmedabad

AHMEDABAD: Uranium — the heavy steel one typically pals with nuclear reactors — is contaminating Gujarat’s groundwater, unearths an elaborate scientific study that covered 16 states. Uranium contamination was once discovered to breach WHO limits of 30 microgram consistent with litre in numerous parts of Ahmedabad district. Extensive use of groundwater for agriculture and different functions, expanding salinity (TDS levels), nitrite pollution from excessive use of nitrogenous fertilisers and fluoride levels are simplest exacerbating the problem.

Today, extra uranium in drinking water is thought to be a explanation why at the back of the increase in continual kidney disease (CKD), as uranium is known to have nephrotoxic effects. The study raised alarms for six of nine places studied in Ahmedabad, three of 20 in Sabarkantha, three of 37 dug well websites tested in Patan and one website online in Gandhinagar. At a lot of these puts, uranium levels have both breached the 30 microgram consistent with litre mark or are getting worse, with levels crossing passing the 15 to 20 microgram consistent with litre mark.

The study was once collectively conducted through R C Jain, advisor to the Gujarat Water Resources Development Corporation, lead authors for analysis Avner Vengosh and Rachel Coyte of Nicholas School of the Environment, Duke University, US, who sampled 324 wells within the crystalline basement and alluvial aquifer rocks of Rajasthan and Gujarat and analyzed the water chemistry. Uranium levels breached the WHO authorized standards in 5 of the 98 wells tested in Gujarat and 75 of the 226 wells tested in Rajasthan.


How does uranium get into the groundwater? Coyte explains, “Many of India’s aquifers are composed of clay, silt and gravel carried down from Himalayan weathering through streams or uranium-rich granitic rocks. When over-pumping of groundwater from these aquifers happens and water levels decline, it enhances oxidation, which in flip strengthen uranium enrichment within the shallow groundwater that remains.”


Others concerned within the study had been Sudhir Shrivastava of the Central Groundwater Board, Abedalrazq Khalil of the World Bank and Lin Ma of the dep. of geological sciences at the University of Texas, who analysed equivalent data from 68 earlier studies of groundwater geochemistry in 14 different Indian states.


In an legitimate unlock Vengosh said that evaluation of previous groundwater studies have printed top levels of uranium contamination in 26 districts in northwestern India and nine districts in southern or southeastern India. “The results of our study strongly recommend there's a wish to revise present water-quality monitoring programmes in India and think again human health risks in areas of top uranium prevalence,” Vengosh said. “Developing efficient remediation applied sciences and preventive control practices must even be a concern.”
