The extent of contamination was quantified using multiple pollution indices, including the geo-accumulation index (Igeo) and enrichment factor. Health risks were evaluated using both deterministic and probabilistic approaches, incorporating Monte Carlo simulation to characterize uncertainty and Sobol sensitivity analysis to identify key influencing parameters. Mean heavy metal(loid) concentrations (mg kg −1 ) decreased in the order of Fe (28,136) > Zn (480.73) > Cr (184.85) > Pb (147.12) > Ni (73.5) > Cu (55.50) > As (15.97) > Cd (5.27). Pollution indices consistently identified Cadmium (Cd) and Lead (Pb) as the primary contributors to soil contamination. Enrichment factor analysis revealed extreme enrichment for Cd, with concentrations exceeding background levels by up to 58 times. Probabilistic risk assessment indicated a high potential for adverse health effects. For children, the non-carcinogenic Hazard Index for lead exceeded the safe limit of 1 in over 50% of simulations. The Total Carcinogenic Risk (TCR) for children surpassed the acceptable threshold (1 × 10 −4 ) in over 80% of simulations for As, Cr, and Cd. For adults, the TCR for Cd exceeded this threshold in over 70% of cases. The 95th percentile of the simulated TCR for children reached 5.7 × 10 −3 , a value 57 times higher than the acceptable limit. Sobol analysis identified the soil ingestion rate as the primary source of uncertainty in the risk models (contributing 68–74%). These findings indicate that the soil contamination poses a significant health risk to the local population, warranting targeted intervention strategies.}, year = {2026}, eissn = {2045-2322} } @article{MTMT:37113525, title = {Integrated assessment of groundwater salinity sources and inter-aquifer mixing dynamics in Siwa Oasis, Egypt: A multi-method approach using self-organizing maps, isotopic tracers, and numerical modeling}, url = {https://m2.mtmt.hu/api/publication/37113525}, author = {Hemida, Mohamed Hamdy Eid and Eissa, Mustafa and Mikita, Viktória and Czímer, Bence and Palcsu, László and Kovács, Attila and Szűcs, Péter}, doi = {10.1007/s10040-026-03078-3}, journal-iso = {HYDROGEOL J}, journal = {HYDROGEOLOGY JOURNAL}, volume = {34}, unique-id = {37113525}, issn = {1431-2174}, abstract = {Groundwater salinization threatens water security for 30,000 inhabitants of Siwa Oasis, Egypt, who depend on two aquifer systems: The shallow Tertiary Carbonate Aquifer (TCA) and deeper Nubian Sandstone Aquifer (NSSA).

Analysis of 153 water samples revealed three distinct hydrochemical groups: High salinity TCA waters influenced by evaporation and recharge from salt lakes, intermediate salinity mixing zones, and low-salinity NSSA paleowaters aged 4,300–14,200 years. Salt lake contributions to TCA groundwater salinity range from 0.6–18%, while fault-controlled NSSA discharge contributes 52–90% to TCA recharge. Predictive modeling indicates the non-renewable groundwaters in the NSSA will experience 30–40 m of drawdown by 2100 under current groundwater abstraction rates, exacerbating TCA salinization.

This study presents a comprehensive assessment of groundwater quality in the Gonbad Plain, Iran, to determine its suitability for drinking and to identify the controlling hydrogeochemical processes. A total of 45 groundwater samples were analyzed for their physicochemical parameters, and the data were evaluated using an integrated approach combining hydrochemical facies analysis, geochemical modeling (PHREEQC), multivariate statistical techniques (Principal component analysis (PCA) and hierarchal cluster analysis (HCA)), and human health risk assessment (Heavy metal pollution index (HPI), Hazard quotient (HQ), Hazard index (HI)). The results reveal a hydrochemical evolution from fresh Ca-HCO₃ type water to saline Na-Cl type water, primarily controlled by three key mechanisms: (1) dissolution of evaporite minerals (halite and gypsum), (2) cation exchange, and (3) evaporation. The Gibbs diagrams confirmed that rock-water interaction and evaporation are the dominant processes governing water chemistry. Iron concentrations varied from 0.01 mg/L to 4.12 mg/L, with a mean of 0.46 mg/L and a standard deviation of 0.66 mg/L. The median iron concentration was 0.27 mg/L. Manganese concentrations ranged from 0.015 mg/L to 0.47 mg/L, with a mean of 0.09 mg/L and a standard deviation of 0.07 mg/L. The median manganese concentration was 0.08 mg/L. The HPI indicated a critical water quality crisis, with 77.8% of the samples being unsuitable for drinking (HPI > 100), primarily due to elevated concentrations of manganese. The non-carcinogenic health risk assessment revealed that while the dermal exposure pathway poses no significant risk, oral ingestion of groundwater presents a potential health hazard, particularly for children. The HI exceeded the safe limit of 1.0 in 11.1% of the samples for children, with manganese being the primary contributor to the risk.

Understanding the dynamic interplay between rainfall, river discharge, and groundwater levels remains challenging due to the complexity of hydrogeological structures and variable recharge conditions. This study investigates the temporal relationships among rainfall, river stage-discharge, and groundwater levels in the Erbil Basin, North Iraq. A multivariate time series framework was employed for the data series spanning 2004–2022, combining wavelet coherence analysis to identify dominant periodicities and temporal correlations, with a vector autoregression (VAR) model to forecast future groundwater fluctuations. The wavelet analysis revealed strong monthly-scale variability during the wet season and a pronounced rainfall-groundwater coherence with a dominant 1-month periodicity, particularly after 2008. Spatial differences in coherence strength across monitoring wells indicate regionally consistent hydrogeological conditions, with stronger coupling observed in wells situated closer to the Lesser Zab River. The impulse response function (IRF) analysis additionally demonstrated positive groundwater responses within 2–6 months following rainfall events, consistent with regional recharge patterns. However, persistent groundwater declines identified in the VAR forecasting model reflect the combined effects of reduced recharge and continuous abstraction pressures. The integrated approach provides a comprehensive assessment of hydroclimatic interactions and groundwater dynamics in the Erbil regional aquifer.

These techniques include self-organizing maps (SOM), hierarchical cluster analysis (HCA), principal component analysis (PCA), and groundwater quality indexing (GWQI). The hydrochemical analysis revealed that Ca-Mg-HCO₃ is the dominant water type, with a temporal shift toward Na-HCO₃, reflecting increased salinity driven by ongoing rock-water interactions. SOM analysis showed a transition from heterogeneous to more uniform groundwater chemistry over time, suggesting greater stability in the aquifer system. Elevated salinity zones shifted spatially due to changes in groundwater recharge and flow patterns, while hardness intensified and expanded, indicating continued carbonate dissolution. HCA highlighted temporal shifts in groundwater composition, with six clusters identified in 2019 and five clusters in 2024, reflecting a gradual homogenization of water quality. PCA further confirmed this trend, linking it to underlying hydrochemical processes, such as water–rock interactions, with limited contributions from anthropogenic influences. The GWQI analysis indicated a general improvement in groundwater quality over time, with most regions meeting drinking water standards.

The methods used included principal component and cluster (dendrogram) analysis to estimate source of ions and contamination. Various indices such as the Heavy Metal Pollution Index (HPI), Metal Index, hazard quotient, hazard index (HI), and cancer risk (CR) were applied to assess both environmental and human health risks. Furthermore, the Monte Carlo method was applied for probabilistic assessment of carcinogenic and non-carcinogenic risks through oral and dermal exposure routes in both adults and children. The results revealed that approximately 16% of the samples fell within the low pollution category (HPI < 100), indicating relatively lower levels of heavy metal contamination. However, the remaining 84% of the samples exhibited high pollution levels, indicating a significant presence of heavy metal pollutants in the northeastern part of the investigated area. The calculated average risk index (RI) for the collected samples was 18.99, with a range from 0.03 to 103.21. This indicates that a large portion, 82% of the samples, could cause low ecological risk (RI < 30), whereas the remaining 18% indicate a significant environmental pollution risk. The HI for oral ingestion showed that adults had HI values ranging from 0.231 to 1.54, while children exhibited higher values, ranging from 0.884 to 5.9 (Fig. 5a).

Accordingly, the sustainability of water resources in this arid environment should be examined in terms of the possibility of groundwater recharge, particularly through runoff water, while identifying the most appropriate potential sites for drilling new water wells to cover current and future needs. The aquifer system of El-Qaa Plain in South Sinai is considered one of the structural basins associated with the tectonic setting of the Gulf of Suez. It is the main source of high-quality water in South Sinai. The present work provided an integration of mathematical flow modeling, hydrochemical composition, environmental isotopic signature, watershed modeling system (WMS), and remote sensing (RS) tools to determine the aquifer sustainability and recharge mechanisms. The obtained results indicated the following: (a) the salinity of the water ranged between 326.4 and 2261 ppm, while the environmental isotope values ranged between −6.28 to −4.48‰ for δ18O and −29.87 to −21.7‰ for δ2H, which reveals the phase of recharge and mixing between ancient water and recent rainwater; (b) sites for three dams in three sub-watersheds were proposed to harvest approximately 790,000 m3/y of runoff water to enhance groundwater recharge of the aquifer system; (c) and five scenarios using MODFLOW indicated that water drawdown is acceptable by adding 10 new production wells (discharge rate increased by 3600 m3/day). Moreover, increasing the recharge rate by 2% from the base case, leads to an increase in the piezometric water level with an average value of 0.13 masl, which reflects the positive effects of the proposed runoff water harvesting facilities.
