Seasonal changes in groundwater quality deterioration and chemometric analysis of pollution source identification in South India
Adithya Vasanthakumari Sivasankara Pillai,Chidambaram Sabarathinam,Chidambaram Sabarathinam,Tirumalesh Keesari,Thivya Chandrasekar,Thilagavathi Rajendiran,Venkatramanan Senapathi,Prasanna Mohan Viswanathan,Dhanu Radha Samayamanthu +8 more
TL;DR: Correlation of geochemical parameters reveals a excellent positive correlation between Ca and NO 3 in SUM, SWM, and NEM due to the dominant of anthropogenic sources and minor influence of weathering process and principal component analysis of different seasons indicates the interplay of natural weathering and anthropogenic factors.
Journal ArticleDOI
Occurrence of Heavy Metals in Groundwater Along the Lithological Interface of K/T Boundary, Peninsular India: A Special Focus on Source, Geochemical Mobility and Health Risk
Thivya Chandrasekar,Tirumalesh Keesari,Gnanachandrasamy Gopalakrishnan,Shankar Karuppannan,Venkatramanan Senapathi,Chidambaram Sabarathinam,Prasanna Mohan Viswanathan +6 more
TL;DR: In this article, the authors focused on the health impacts due to the heavy metals pollution in a known Cretaceous-Tertiary (K/T) contact region (Tiruchinopoly, Tamilnadu) of peninsular India, using various pollution indices, statistical, and geochemical analyses.
Journal ArticleDOI
Identification of groundwater potential zones using geospatial approach in Sivagangai district, South India
Agastheeswaran Vellaikannu,Udayaganesan Palaniraj,Sivakumar Karthikeyan,Venkatramanan Senapathi,Prasanna Mohan Viswanathan,Selvam Sekar +5 more
TL;DR: In this paper, an analytical hierarchy process (AHP) was used to compute the weightage for each layer with respect to the relative importance of groundwater potential index and all the thematic layers were reclassified according to their water-bearing properties with the weightages derived by AHP.
Journal ArticleDOI
Influence of variations in rainfall pattern on the hydrogeochemistry of coastal groundwater—an outcome of periodic observation
Thilagavathi Rajendiran,Chidambaram Sabarathinam,Chidambaram Sabarathinam,Thivya Chandrasekar,Tirumalesh Keesari,Venkatramanan Senapathi,Pethaperumal Sivaraman,Prasanna Mohan Viswanathan,Ganesh Nagappan +8 more
TL;DR: The rainfall and water level gave a significant variation in the geochemical process of groundwater in the coastal aquifer system, which was revealed to be dissolution and leaching during 2006~2011 years and seawater intrusion along with ion exchange during 2011~2016 years.
Journal ArticleDOI
Geochemical (process based) characterization of groundwater along the KT boundary of South India
Thivya Chandrasekar,Chidambaram Sabarathinam,Devaraj Nadesan,Thilagavathi Rajendiran,Banajarani Panda,Tirumalesh Keesari,Prasanna Mohan Viswanathan,Vasudevan Utharapathi,Ramanathan Alagappan +8 more
TL;DR: In this article, a study has been carried out in the Cretaceous-Tertiary boundary along the contact zones of hard rock, limestone and sedimentary formations to discern the geochemical processes governing the groundwater chemistry.
