Journal ArticleDOI
Fluoride dynamics in the granitic aquifer of the Wailapally watershed, Nalgonda District, India
TL;DR: The Wailapally granitic aquifer of Nalgonda district, Andhra Pradesh, India has high concentrations of fluoride (up to 7.6 mg/L) as discussed by the authors.
Journal ArticleDOI
Geochemical controls on fluoride concentrations in groundwater from alluvial aquifers of the Birbhum district, West Bengal, India
TL;DR: In this article, the presence of intercalated zeolitic clay within the aquifer sand is the major source of fluoride contamination in groundwater in Birbhum district, West Bengal, India.
Journal ArticleDOI
Differentiation of palaeomarine and modern seawater intruded salinities in coastal groundwaters (of Karaikal and Tanjavur, India) based on inorganic chemistry, organic biomarker fingerprints and radiocarbon dating
TL;DR: In this paper, the Karaikal and Tanjavur coastal aquifers of Tamil Nadu have been examined and the results show that the Pliocene aquifer possesses characteristic palmitoleic and oleic acid biomarkers, apparent 14 C ages of more than 20 000 years and high I/Cl ratio.
Journal ArticleDOI
Groundwater Recharge In Semi-Arid Regions Of India: An Overview Of Results Obtained Using Tracers
TL;DR: In this article, the authors investigated various geologic units, including unconsolidated, semiconsolidated and consolidated materials and crystalline granitic/gneissic rocks, and measured the natural direct groundwater recharge in semi-arid/arid regions of India using techniques that employ environmental, geochemical, and artificial tracers.
Journal ArticleDOI
Isotopic fingerprints of paleoclimates during the last 30,000 years in deep confined groundwaters of southern India
TL;DR: Isotopic and geochemical evidence of paleoclimates, especially for the last glaciation, has been obtained from deep confined groundwaters of southern India as discussed by the authors, showing distinct excursions inferred to be related to climatic variations.
