Special Issue Information

Dear Colleagues,

Groundwater provides drinking water for up to 50% of the global population and remains a critical resource for sustainable development. The quantity and quality of groundwater resources face significant challenges due to climate change, human activities, and natural geological processes. Understanding the complex interactions between groundwater, sediments, and various contaminants is crucial for effective resource management and protection.

Recent advances in hydrogeological research have led to innovative approaches in studying groundwater quantity and quality dynamics. Researchers are employing state-of-the-art technologies, including environmental tracers, isotope techniques, and artificial intelligence, to help us better understand groundwater–sediment interactions, contaminant transport mechanisms, and aquifer recharge processes. These methods provide valuable insights into both the quantitative aspects of groundwater resources and the qualitative changes influenced by sediment–water interactions.

The role of sediments in groundwater systems is particularly significant, as they can act as both sources and sinks for various contaminants, affecting water quality while also influencing aquifer storage capacity and groundwater flow patterns. Advanced numerical modeling approaches, coupled with high-resolution monitoring systems, are enabling researchers to better understand these complex relationships and predict changes in both water quantity and quality under various environmental conditions.

Emerging focus areas further highlight the need for integrated investigations. Natural organic matter and microbial communities play a critical role in governing biogeochemical reactions, contaminant degradation, and redox conditions within aquifers. Microbial pollution, often linked to anthropogenic activities, poses direct health risks and requires improved source tracking and attenuation assessment. Meanwhile, groundwater–surface water interactions—particularly in hyporheic zones—control the exchange of water, solutes, and energy, influencing contaminant fluxes and ecosystem functioning. At larger scales, regional water environment evolution, driven by climate variability and long-term human intervention, shapes the spatial and temporal trends of both water quantity and quality. Detailed characterization of sediment properties (e.g., grain size, mineralogy, organic carbon content) is essential to decipher their roles as pollutant carriers or natural remediation agents. Addressing these interconnected aspects is key to developing sustainable groundwater management and protection strategies.

This Special Issue of Water aims to focus on innovative methods and technologies in groundwater research, particularly emphasizing the interconnections between water quantity, quality, sediment interactions, and broader hydrogeological dynamics. We invite contributions that integrate field observations, experimental studies, and advanced modeling to advance our understanding of groundwater systems under multiple pressures. We aim to showcase cutting-edge research that addresses these critical aspects, providing new perspectives and solutions for sustainable groundwater resource development.

Soil pH is a fundamental geochemical parameter with direct implications for environmental quality, but its spatial drivers in geologically complex mountain regions remain poorly understood. This study investigated surface soil pH across 452 sites in Pingquan City, a semi-arid, lithologically heterogeneous mountainous area of Hebei Province, China. The results show that the soil in Pingquan City is predominantly alkaline, with higher pH in southwestern and northeastern areas and lower pH in the northwest. Soil pH ranged from 4.62 to 9.98, with strong positive spatial autocorrelation. Comprehensive quality assessment indicated that the overall soil quality is moderately low. GeoDetector analysis identified average annual temperature, soil texture, elevation, and bedrock lithology as dominant structural drivers, with bi-factor enhancement interactions. GeoSHAP further uncovered two local effects: precipitation exerts a positive influence on pH in carbonate-rock-dominated areas, reversing the leaching–acidification pattern; and temperature functions as a proxy variable integrating co-varying topography, parent material, and texture rather than a direct thermal driver. The combined application of spatial autocorrelation, GeoDetector, and GeoSHAP provides an effective framework for identifying spatial phenomena, discriminating dominant drivers, and explaining local variations. These findings support regional soil quality assessment and land management, and provide a geochemical baseline for safeguarding groundwater resources in mountainous regions. Full article
