“…Finally, the waters of the surface canals (C) show values attributable to sub-modern waters but with slightly higher values of 3 H (between 4 and 5 TU), probably relating to a possible mixing with modern waters due to their presence on the surface and direct contact with the atmosphere, as described in Mahlangu et al ( 2020 ) and Malov ( 2021 ).…”

“…Geochemical and isotopic analysis was used to investigate the origin of the water samples collected and analyzed, discriminating the different types of water, and understanding their interactions. This approach is widely used in literature especially to date water resources with wide applications both in Italy (Mayer et al, 2014 ; Romano et al, 2018 ; Telloli et al, 2022 ), in Europe (Balocchi et al, 2022 ; Brkić et al, 2020 ; Malov, 2021 ), and all over the word (Copia et al, 2020 ; Varol et al, 2020 ).…”

The Friuli-Venezia Giulia Region (north of Italy) is characterized by the presence of high-quality freshwater resources which benefit local citizens, animals, environmental habitats, and also agriculture and production activities. Waters from wells, canal, and wastewater selected in the Fiume Veneto area, through a detailed lithological modeling, were sampled and analyzed to characterize them from a geochemical point of view. The chemical and isotopic characterization made it possible to establish provenance, and the average age of water used, making available the estimation of the relationships between recharge capacity and water use in the Fiume Vento area. The focus of this study is to define the average age of the resources based on the time required for the recharge contributions to compensate the losses induced by exploitation. The results made it possible to support the plans for a water balance using the provenance and average age of water sources for the protection of water reserves formed by the multi-aquifer system of the high and medium Friuli plain. The methodology applied has followed the legislation of the water directive considering the overexploitation due to unauthorized withdrawals of the sampling area.

“…(1990) claimed that recharge in unfrozen soil occurs predominantly in coarse-grained sediments and less in fine-grained sediments and compact soil. Therefore, in continuous permafrost zones, recharge is mostly restricted to taliks (Clark et al, 2001;Scheidegger et al, 2012;Kane et al, 2013;McKenzie and Voss, 2013;Wellman et al, 2013;Walvoord and Kurylyk, 2016;Crites et al, 2020;Malov, 2021) and in the case of suprapermafrost groundwater to infiltration of the active layer (which can be limited during winter) (Cochand et al, 2020). The research of the continuous permafrost zone in QTP also showed that vertical water penetration was weak and therefore that meteoric water, surface water and shallow groundwater can only laterally or horizontally recharge deep groundwater through taliks or other vertical discontinuities (Bibi et al, 2019).…”

This study reviews the available and published knowledge of the interactions between permafrost and groundwater. In its content, the paper focuses mainly on groundwater recharge and discharge in the Arctic and the Qinghai-Tibet Plateau. The study revealed that the geochemical composition of groundwater is site-specific and varies significantly within the depth of the aquifers reflecting the water-rock interactions and related geological history. All reviewed studies clearly indicated that the permafrost thaw causes an increase in groundwater discharge on land. Furthermore, progressing climate warming is likely to accelerate permafrost degradation and thus enhance hydrological connectivity due to increased subpermafrost groundwater flow through talik channels and higher suprapermafrost groundwater flow. In the case of submarine groundwater discharge (SGD), permafrost thaw can either reinforce or reduce SGD, depending on how much pressure changes affecting the aquifers will be caused by the loss of permafrost. Finally, this comprehensive assessment allowed also for identifying the lack of long-term and interdisciplinary in situ measurements that could be used in sophisticated computational simulations characterizing the current status and predicting groundwater flow and permafrost dynamics in the future warmer climate.

“…At the sub-seasonal scale, basic water chemistry (electrical conductivity, pH) and DOC observations during a high-frequency sampling campaign revealed seasonality in DOC origin and pathways in a medium catchment of the Northern Yenisey region [45]. In permafrost groundwater studies, radioactive tritium, radon ( 222 Rn), and chlorofluorocarbons, which only recently appeared in the atmosphere, are used jointly to infer groundwater recharge and residence times in intra-and supra-permafrost aquifers [46][47][48][49]. Tritium release from thawing permafrost may significantly enrich surficial waters and groundwater seepage, especially in discontinuous permafrost [50].…”

Major ions, stable isotopes, and trace elements, including rare earth elements (REEs), are used as natural tracers in the qualitative assessment of potential water sources in lakes and rivers of the upper Yana River basin, between Verkhoyansk and Chersky Ranges, during the late summer period. Three distinct regions were sampled, and a dominant water source in each region was qualitatively inferred from water chemistry data. The REE distribution pattern was found to be highly regional and controlled by pH and carbonate contents. Mountain headwater stream at the Verkhoyansk Range north slope, the Dulgalakh River, shows an input from a mixture of shallow groundwater and icing meltwater, with a depleted isotopic signature (δ18O below –21‰), d-excess (dex = δ2H − 8·δ18O) above 18, enrichment in Mg and Sr, and depletion in heavy REEs. The Derbeke Depression lakes and streams are fed by rainfall having ultra-low total dissolved solids (TDS) content, below 25 mg/L, and a convex-up REE pattern. In a medium mountainous river at the Chersky Range flank, the Dogdo River, leaching through fissured Jurassic carbonates is a dominant runoff pathway. Riverine water is heavily depleted in light REEs, but enriched in Mo, Rb, Sb,W and U. In the Dulgalakh River water, high positive Sm and Gd anomalies were observed, attributed either to local geology (greenshists), historical mining legacy, or contemporary winter road operations.
