“…These conclusions diverge from the view of Mishra (2012) for the interior aquifers of Kendrapara district, where two distinct zones exist at shallow subsurface, one within 15 m of the ground surface and the other at about 120 m-130 m below ground level. However, the research of Das et al (2016a) indicates a profound increased chaotic nature across the landscape contiguous to the River Mahanadi with deeper aquifer condition in contrast to that happening within the interfluves of Mahanadi and Brahmani of northern part (Fig. 4).…”

“…The Quaternary deposits are a slice of the sedimentation taken place in the coastal depression of the Odisha coast and those fitting to the Mahanadi onshore basin. These formations are very complicated concerning their depositional account and seem to have been momentously impacted by the basement tectonic elements (Das et al, 2016a;Das et al, 2016a;Das et al, 2016c).…”

“…While coastal aquifers are subject to both marine and continental influences, another obscuring factor of key importance is the large-scale structural variations of the concerned sedimentary basin which can lead to groundwater mixing (Schwartz and Zhang, 2004). Fault structures disturb the hydraulic behavior of the aquifers in a significant way and expressively influences the spatial disparity of hydrogeochemical facies (Das et al, 2016a;Das et al, 2016a;Das et al, 2016c;Chihi et al 2015).…”

“…However, the investigation of Mishra (2012) designates a substantial less salinity of the subsurface for western section of the district. Together, the aquifers of northern fragment demonstrates an upsurge in salt content during postmonsoon phase where the cationic exchange course within the sediments theatres a overriding role in bringing about the geochemical changes (Das et al, 2016a;Das et al, 2016a;Das et al, 2016c). Comparable to Total Dissolved Solids (TDS) in groundwater, the chloride activity of subsurface waters also depicts weighty augmentations indicative of saline influence.…”

“…Such decrease in water level below the sea level may lead to marine water incursion in future. Apart from this, the inherent subsurface water value complications such as superfluous iron, salinity and fluoride concentration that have been chiefly geogenic may become magnified from anthropogenic influence if the exploitation of the fresh aquifers goes persistent (Das et al, 2016a;Das et al, 2016a;Das et al, 2016c). This is a perilous issue demanding an apt supervision of the reserve.…”

The alluvial aquifers of Mahanadi delta are of Quaternary age. Because of the presence of numerous perched aquifers, they are commonly referred to as aquifer systems. Not only these hydrostatic units have its place within the massive intricate Quaternary deposits of the coastal depression, but also, they appear to have been momentously affected by the basement structural elements as well as from the land-sea exchanges of geologic past. This is precisely why; the aquifers depict a very muddled distribution of diverse groundwater types both vertically as well as sideways. The lithostratigraphic components are multifaceted combinations of gravel, sand, silt and clay deposits with an overall layered assembly across the landscape where the thickness of the discrete horizons lessens with depth. Commonly, the sandy and gravelly layers produce fresh groundwater away from the shore on the western side close to the hard rock lands and the aquifer assemblage adjacent to the coast are of brackish as well as freshwater nature. The present article summaries an appraisal of the saltwater contamination of these deltaic aquifers from the technical studies carried out by the several investigators.

This study aims to investigate the intricate relationship between geological structures, water chemistry, and isotopic composition in order to gain a deeper understanding of the origins and recharge mechanisms of thermal–mineral waters in the Kyllini region. The research integrates tectonic analysis, hydrochemical data, and stable isotope measurements to delineate recharge zones and trace the origin of these unique water sources. The methods used for delineation are the geological and tectonic study of the area, as well as hydrochemical and isotopic data analysis. The findings highlight that tectonic activity creates preferential flow paths and consequently influences the hydrogeological framework, facilitating deep circulation and the upwelling of thermal waters. Monthly analyses of groundwater samples from the Kyllini thermal spring were conducted over one hydrological year (2019–2020) and compared with data from the area collected in 2009. The hydrochemical profiles of major and minor ions reveal distinct signatures corresponding to various water–rock interactions, while stable isotope analysis provides insights into the climatic conditions and altitudes of recharge areas. Hydrochemical analyses reveal the composition of thermal–mineral waters, aiding in the identification of potential sources and their evolution. The conceptualization of Kyllini contributes to the deeper understanding of the intricate interplay between tectonics, hydrochemistry, and stable isotopes. During a hydrological year, the water type of Kyllini’s spring groundwater remains the same (Na-Cl-HCO3), presenting only slight alterations.
