This study utilized the IPTA-based SBAS-InSAR method, incorporating multiple data sources to obtain surface deformation results for Tongzhou District from 2003 to 2018, and the distribution characteristics and spatiotemporal evolution patterns of land subsidence were studied in Beijing's Tongzhou District. Additionally, using the MIC method, combined with spatial analysis techniques and statistical methods, the study analyzed the impact of factors such as groundwater levels in different aquifers and the thickness of compressible layers on land subsidence. The results revealed that land subsidence in Beijing's Tongzhou District is unevenly distributed, with major subsidence areas concentrated in BMAC and Taihu. During the study period, surface deformation rates ranged from −147 to 24 mm/yr, showing an initial acceleration followed by a deceleration trend. The third and fourth aquifers were identified as the dominant factors influencing changes in land subsidence, and interactions between different aquifers may also play a role. For varying compressible thicknesses, the second and third layers were the primary contributors to land subsidence. This study provides valuable insights into the mechanisms of land subsidence in Tongzhou District, offering a foundation for further research and informing decision-making for sustainable urban development.</div></div>","PeriodicalId":37879,"journal":{"name":"Groundwater for Sustainable Development","volume":"30 ","pages":"Article 101476"},"PeriodicalIF":4.9,"publicationDate":"2025-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144279887","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}

Lakes and wetlands -the most abundant inland water bodies- are particularly affected. This study assessed the impacts of anthropogenic interventions on the hydrological dynamics and surface water-groundwater interactions in artificially connected shallow lakes of the Southern Pampa plain (La Chanchera-La Brava system). A small, unconnected lake (Médano de Castro lake) was also analyzed. The canal-connected lakes and associated groundwater are alkaline (mean pH 8.6), brackish (TDS from 1.6 to 13.2 g L⁻¹), and of the sodium-chloride/sodium-non-dominant type, exhibiting minimal seasonal variations. In contrast, the unconnected Médano de Castro lake has sodium bicarbonate-type waters, with salinity increasing from 6.7 g L⁻¹ in the dry (austral winter) to 12.3 g L⁻¹ in the wet (austral summer) seasons. Isotopic modeling (δ¹⁸O) applied in both La Chanchera and Médano de Castro lakes indicates that groundwater inflow occurs year-round, at rates approximately seven times higher in the wet season due to water table rising. Both lakes are throughflow systems with short water residence times (&lt;1 year), indicating a constant water exchange. The hydrochemical and isotopic evidence indicates that the Médano the Castro lake receives local groundwater recharge from the surrounding dunes, imparting a bicarbonate signature and preventing its desiccation. In contrast, the canal-connected La Chanchera lake receives the input from regional groundwater with a chloride-sulfate composition. This study highlights the importance of understanding lake-groundwater dynamics in regions facing agricultural expansion and climate pressures.</div></div>","PeriodicalId":37879,"journal":{"name":"Groundwater for Sustainable Development","volume":"30 ","pages":"Article 101475"},"PeriodicalIF":4.9,"publicationDate":"2025-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144306319","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}

This study optimized the HTC process parameters (temperature and time) to produce an efficient adsorbent from Sotol bagasse (<em>Dasylirion leiophyllum</em>), targeting the simultaneous removal of arsenic (As) and fluoride (F). A 3^K full factorial design was employed to synthesize hydrochars, which were evaluated based on yield, severity factor, and adsorption capacity. Characterization via scanning electron microscopy (SEM), infrared spectroscopy (FTIR), and thermal analysis (TGA) revealed distinct physicochemical properties among the materials. Textural parameters were acquired, attaining surface areas ranging from 2.9 to 8.9 m² g⁻¹. Adsorption tests in real groundwater demonstrated simultaneous removal capacities of 0.98 μg g⁻¹ for As and 91.95 μg g⁻¹ for F. Pareto statistical analysis identified the optimal hydrochar, synthesized at 300 °C for 80 min, as the most effective adsorbent. The effect of initial contaminant concentration was evaluated for both arsenic and fluoride, within the typical groundwater range. Adsorption isotherms were fitted into the Langmuir and the Freundlich models, providing essential parameters such as adsorption capacity and affinity constants. The hydrochar also effectively removed nickel alongside As and F. In addition, adsorption-desorption cycles were performed to demonstrate the feasibility of achieving the contamination limits set by the World Health Organization (WHO) for drinking water. Compliance was attained in two adsorption cycles for As (0.5 g hydrochar dose). For F, increasing the adsorbent dosage attained the WHO fluoride limits without needing pH adjustment.</div></div>","PeriodicalId":37879,"journal":{"name":"Groundwater for Sustainable Development","volume":"30 ","pages":"Article 101471"},"PeriodicalIF":4.9,"publicationDate":"2025-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144306318","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}

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.

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.

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.

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.

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 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.
