Topic Information

Dear Colleagues,

Urbanization is the predominant global phenomenon of our time, and sustainable urban development is therefore now one of the greatest challenges faced by the contemporary world. The subsurface plays a range of roles in the complex process of urbanization, including buildings' development, constructing roads for transportation, and providing water supply, drainage, sanitation and, in some cases, solid-waste disposal. For most cities, the groundwater system commonly represents a ‘linking component’ between various elements of the urban infrastructure. Since urban processes have an influence on groundwater and groundwater conditions have an impact on the urban infrastructure, groundwater systems exhibit a close relation with the processes of urbanization, and this continuously progresses with the urban development cycle. Consequently, most cities around the world face issues related to urban hydrogeology which require at least as much attention as that given to other planning-related problems in urban areas. Urban groundwater problems are now usually predictable. However, they are often not predicted early enough, as actions usually respond to emergencies rather than planning. Consequences resulting from a lack of accurate and detailed knowledge of the underground environment and the interaction between the urban groundwater and urban infrastructure is faced by cities around the world in economic, environmental, social, legal and political terms. The lack of data and planning, as well as the discrepancies in communication between the scientific community and city managers, increase difficulties in solving urban hydrogeology problems. To supply this understanding, experts have to use robust datasets of urban fabric, infrastructure networks, groundwater and geothermal energy systems at the city scale. Furthermore, relevant knowledge and understanding from these must also be accessible to urban planning processes. Over the last few decades, a progressive advancement in the scientific understanding of urban hydrogeological processes and the groundwater regimes of a substantial number of cities has been documented. This extensive palette of subsurface challenges that cities have to contend with lay at the core of the sustainability of the urban water cycle. This is threatened by the increasing scale and downward extent of urban subsurface construction, including utilities (cables, sewage, drainage), transportation (tunnels, passages), and storage (cellars, parking lots, thermal energy). The cumulative impact of this subsurface congestion on the surrounding geology, and especially the groundwater system, have to be persistently studied. Key connections amongst urban hydrogeology activities will be identified as consistent scientific results and good practice in relation to subsurface data. This Special Issue will encourage cross- and trans-disciplinary, mutually beneficial dialogues between the providers and consumers of urban groundwater data and knowledge offering new perspectives on the existing research themes.

The purpose of this research was to understand the hydrogeochemical characteristics and assess the quality of phreatic and confined groundwater in southern Hebei Province. A total of 107 groundwater samples were collected, representing different aquifer conditions over the study area. Multivariate statistical analysis, hydrochemical maps, ionic ratio coefficients, geographic information system (GIS) and geochemical simulation were comprehensively and systematically used to reveal the hydrochemical characteristics of groundwater and its controlling mechanism. The results revealed that both phreatic (pH = 7.02–9.08) and confined groundwater (pH = 7.00–10.60) were slightly alkaline. The hydrochemical types were mainly present as the HCO3-Ca-Mg type in the western premontane area and mixed Ca-Mg-SO4-Cl and Na-Cl-SO4 types in the eastern plains. The hydrochemical composition was dominated by water–rock interactions of natural processes, including silicate weathering, dissolution of sulfate minerals (gypsum, anhydrite), and cation-exchange adsorption. Anthropogenic activities were the main factor causing NO3 content in some groundwater samples to exceed the geochemical baseline. The hydrogeochemistry of groundwater in different aquifers was significantly varied. The average contents of TH, TDS, Na+, Ca2+, Mg2+, Cl and SO42− in phreatic aquifers were significantly higher than those in confined aquifers. The Entropy Weighted Water Quality Index (EWQI) results revealed that 17.78% of phreatic and 50% of confined water samples were meeting the purpose of drinking water. The groundwater samples with EWQI values exceeding 100 were mainly situated in the Handan urban area and the eastern region of Xingtai City, which should be avoided for direct utilization and needs to be improved through protection and management measures, to enhance the quality of groundwater. Correlation analysis showed that groundwater quality was significantly dominated by TH, TDS, Na+, Mg2+, Cl and SO42− concentrations. Full article
