CHENNAI: In a huge relief to the Department of Atomic Energy (DAE), a recent study by the National Geophysical Research Institute (NGRI) has concluded that there was no evidence to prove the existence of a submerged volcano off the Puducherry coast, which could have posed a danger to nuclear establishments at Kalpakkam, some 80 km from here.
“The literature review, existing satellite and ship-borne bathymetric and geophysical data do not lend any credible evidence for the presence of submarine volcano,” the 110-page ‘Status report on an unconfirmed submarine volcano off Pondicherry coast’ by Hyderabad-based NGRI stated….

HYDERABAD: The recent spate of moderate to heavy rains in the city may have boosted the groundwater levels by at least half a metre, but a new report reveals that the water thus recharged is highly contaminated with fluorides, nitrates and large quantities of iron.
A report on the state’s groundwater profile by the Central Groundwater Board (CGWB) says harmful chemicals are present in the water beyond the permissible limits. “It is bad news for the people as the report mentions a rise in the nitrate levels in the water. The basic source of nitrates in water sources is from sewerage, which seeps from improperly built septic tanks,” Dr Shakeel Ahmed, chief scientist, National Geophysical Research Institute (NGRI), told TOI…..

JAISALMER: For the first time in India, groundwater surveys using heliborne transient electromagnetic technique will be tried for aquifer mapping. This will be a pilot project carried out in five States, including Rajasthan and the geophysical survey in the state will be done in Jaisalmer and Dausa.
Dr Shakeel Ahmed, chief scientist and Dr Subash Chandra, scientists of CSIR-National Geophysical Research Institute, Hyderabad said six study areas in Tamil Nadu, Karnataka, Maharashtra, Biharand Rajasthan were selected following the veracity of geological formations that form the ground water system. Desert areas in Jaisalmer district and a typical sedimentary and hard rock combined aquifer system in Bandikui in Dausa district have been identified in Rajasthan….
