Serbia consists of 26 districts with a population of approximately 6.8 million inhabitants. Individuals in different districts are exposed to varying physicochemical water quality. Irregularities in physicochemical water properties may be linked to malignant diseases. This study aimed to investigate the association between the percentage of water which does not meet the standards for both physicochemical properties and residual chlorine, and standardized incidence of most common malignancies in Serbia. In 2013, 18.9 % of 76,758 water samples in Serbia were non-compliant (0 % in Kolubara, 97.4 % in Middle Banat), and in 2021, 16.5 % of 93,144 samples failed standards (0.9 % in Macva, 97.8 % in North Banat). A significant positive correlation was observed between the percentage of unsatisfactory physicochemical water samples from public water supply systems and water facilities and the standardized incidence of colon and rectal cancer in males and females, any cancer type in both sexes, and ovarian cancer in females. However, no significant correlation was observed for leukemia and pancreatic in males, brain tumors or lung cancer in both sexes. Bladder cancer in males was associated with exposure to residual chlorine which surpass recommended concentrations. Study findings suggest that exposure to water that does not meet adequate physicochemical standards may be associated with an increased risk of various cancer types, while residual chlorine above recommended standards seems associated with increased incidence of bladder cancer.</div></div>","PeriodicalId":37879,"journal":{"name":"Groundwater for Sustainable Development","volume":"30 ","pages":"Article 101473"},"PeriodicalIF":4.9,"publicationDate":"2025-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144221322","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The analysis includes data collected by the regional monitoring network in Turin and surrounding areas between 2010 and 2022. During this period, an average decrease in the water table of approximately 1 m and an increase in the GW temperature (GWT) of approximately 0.5 °C were observed. The GWT and water table data were also measured during three field campaigns in 2022 using a network of 31 monitoring points in the city of Turin. The data show that GW flows from west to east towards the Po River, with values ranging from 240 m a.s.l. to approximately 210 m a.s.l. Moreover, a decrease in the water table depth throughout the monitored year was observed. The GWT increases from west to east in the flow direction, with values ranging from 13 °C to 17.5 °C. The temperature profiles and the spatial distribution show typical seasonal dynamics following air temperature fluctuations. Seasonal variations are diminished by the saturated and unsaturated zones, with the GWT stabilising below 4–6 m from the water table and 20 m below ground level. This comprehensive analysis highlights the impact of anthropogenic activities and climate change on GWT and emphasises the need for improved monitoring and management strategies to protect GW resources, especially in urban areas.</div></div>","PeriodicalId":37879,"journal":{"name":"Groundwater for Sustainable Development","volume":"30 ","pages":"Article 101472"},"PeriodicalIF":4.9,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144221321","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this issue, identifying GW critical zones (GWCZs) is more crucial than identifying GW potential zones. This paper delineates GWCZs in the Sirjan district by integrating geographic information system (GIS) and multi-criteria decision-making (MCDM) techniques. Two scientific MCDM models, including the analytic hierarchy process (AHP) and multi-influencing factors (MIF), were employed to create a GWCZs map. Within the GIS platform, the field data were applied to create, classify, and assign weights to thematic layers of Annual GW discharge (AGD), water well density (WWD), aquifer recharge (AR), aquifer lithology (AL), aquifer thickness (AT), and GW quality change (GQC). Subsequently, the GWCZs map was generated by applying the overlay weighted-sum method to the six different layers. Using AHP, 10.04, 23.62, 32.8, and 33.54 %; and using MIF, 10.13, 23.36, 40.59, and 25.92 % of the study area were classified into critical, sub-critical, semi-balanced, and balanced zones, respectively. The regression analysis and receiver operating curve (ROC) techniques were utilized to assess the reliability of the models. The comparison revealed that both models have acceptable results. However, the MIF method, with an R² of 0.88 and Area Under Curve (AUC) of 0.83, was more reliable than the AHP method, with an R² of 0.86 and AUC of 0.81.

Use of graphene oxide for removing toxic metal ions like lead, arsenic, and cadmium is regarded as an efficient and practical method. However, its effectiveness is limited by GO aggregation, leading to decreased performance. In this study, a composite material (rGO-Zn/Al LDH) combining reduced graphene oxide and zinc-aluminium double-layered hydroxide was successfully synthesized using a simple co-precipitation technique. The layered structure of rGO-Zn/Al LDH was confirmed by the structural and morphological characterization. This composite was employed for Pb(II), As(V), and Cd(II) remediation from water. A comprehensive evaluation was conducted through a series of batch adsorption studies to thoroughly comprehend the influence of different parameters on the rGO-Zn/Al LDH removal efficiency. To optimize the adsorption process under different variables, the RSM-CCD approach was also employed. The results of isotherm and kinetic studies revealed that the adsorption process adheres to the Langmuir isotherm model and follows second-order kinetics. rGO-Zn/Al LDH maximum adsorption capacity was determined to be 280.11 for Pb(II), 227.27 for As(V) and 178.25 mg/g for Cd(II), respectively.

The spatial distribution of these parameters was mapped using the Geographic Information System (GIS) tool.

The aquifer has historically benefitted from natural recharge and inputs from the Lebna dam reservoir (constructed in 1986), which has mitigated saline intrusion. A severe drought period from 2020 to 2023 significantly impacted groundwater resources and agricultural productivity, coinciding with a near depletion of the dam reservoir. This research aims to characterise this drought period (2020–2023) and assess its impact on the coastal groundwater resources and agriculture. A multidisciplinary approach was employed, combining hydrogeological monitoring (Groundwater levels and salinity from 181 wells), isotopic analysis (δ¹⁸O, δ²H), remote sensing (NDVI, Landsat), drought indices (SPI), and field surveys. Results indicate a pronounced rainfall deficit (SPI values from −0.4 to −1.2) and a 63 % reduction in irrigated agricultural land compared to 2019, based on surveys of 30 farmers. NDVI analyses showed reductions in vegetation cover and water body of 45 % and 77.78 %, respectively, during the dry season and 93.6 % and 84 % during the wet season from 2019 to 2023. Comparative analysis of groundwater level and salinity measurements from 181 wells in 2019 and 2023 highlighted a piezometric drop of 9 m below sea level (mbsl) and a significant salinity increase, with electrical conductivity reaching up to 21 mS/cm. The dam filling in 2019 raised groundwater levels, while its near-empty state between 2020 and 2023 resulted in lowered groundwater levels. Isotopic analyses of the δ¹⁸O and δ²H revealed significant groundwater recharge from the dam in 2019, as evidenced by values near the Global Meteoric Water Line (GMWL). In contrast, no recharge occurred in 2023 due to extremely low reservoir levels (12.85–10.80 m).
