Special Issue Information

Dear Colleagues,

Groundwater contamination became an environmental problem of worldwide concern decades ago. Contaminant hydrogeology is a research field that addresses migration, transformation, and the fate of contaminants in groundwater systems. It has a feature of interdisciplinarity and incorporates the knowledge or research methods from geology, groundwater hydrology, fluid dynamics, water chemistry, microbiology, and mathematics. Such a feature has become more significant in recent years with the emergence of new contaminants, the upgrade of contamination characterization technologies, and the development of computing science.

This Special Issue aims to address the recent advances of contaminant hydrogeology and emphasizes the following topics:

  • Contaminant transport theories
  • Mathematical modelling of contaminant transport
  • Methods and tools for computing contaminant transport
  • Contaminant source identification
  • Surface water and groundwater interaction for contaminant migration
  • Transformation and fate of contaminants
  • Hydrogeological characteristics of emerging contaminants
  • Hydraulic and geophysical methods for contaminated site characterization
  • On-site and real-time analysis of contaminants
  • In situ groundwater remediation technology
  • Regional groundwater contamination impact and management

Submissions of both original research articles and review articles are welcome. In addition, articles with remarkable contributions to recent conferences in this field are also welcomed in this Special Issue. We hope that this collection of articles will highlight the recent progress in the area of contaminant hydrogeology and serve as an inspiration for those working in this area.

Here, we describe and discuss a method based on microscopical field of view (FOV) area to estimate diatom absolute abundances (densities or concentrations), and we statistically verify its reliability, also comparing it to another commonly used method (microspheres). To test the new method, we purposely performed replicate counts, both with the FOV and with the microsphere method, on both subfossil and recent material (samples) from mires. Intraclass correlation (ICC) revealed a high degree of agreement between the measurements obtained for the replicates with each of the two methods, suggesting that both are reliable for measuring diatom valve concentrations. However, the FOV consistently overestimated diatom absolute abundances, as compared to the microsphere method, and the ICC value used to assess the reliability of the two methods combined suggested that the two methods cannot be used interchangeably. The FOV method is relatively simple, has a lower cost, wider applicability, higher resolution, and warrants compatibility with existing datasets. However, there may also be drawbacks, such as the potential for sample distortion during the concentration process. Therefore, it is important to carefully evaluate the strengths and limitations of the different methods before adopting one for specific research or applied questions. Full article

Drilling has been conducted to investigate the petrogeochemistry of the Late Pleistocene Guxiangtun Formation and Holocene Wenquanhe Formation in Northeast China. Both Guxiangtun and Wenquanhe Formations are fluvial facies, which are composed mainly of quartz and feldspar, with minor mica and clay minerals. To understand the provenance and tectonic setting of these sediments, geochemical analyses of fifteen selected samples from the drill core have been carried out. Compared to the composition of the upper continental crust (UCC), the sediments exhibit higher SiO2, similar TiO2 and K2O, and lower Fe2O3, MgO, MnO, CaO, and Na2O contents. The bivariant plot of Th/Sc versus Zr/Sc ratios indicates the contribution from recycled sedimentary provenance for our studied sediments; furthermore, the low to medium degree of weathering of these sediments is commonly indicated by the chemical index of alteration (CIA) of 52. The discriminant function diagram using major elements shows a mixed provenance of the sediments, including quartzose sedimentary and felsic igneous rocks. According to the Fe2O3+MgO vs. K2O/Na2O plot and Th–Sc–Zr/10 diagram, the sediments under the investigation fall mostly within the active continent margin field. Full article

In the Egyptian deserts, new land reclamation projects have been recently established to meet the increasing-population growth rate and food demand. These projects mainly depend on the different groundwater aquifers. El-Farafra Oasis is one of the “1.5-million-feddan reclamation project” areas recently established in the Western Desert of Egypt where the only available water source is the world’s largest fossil freshwater reservoir “the Nubian Sandstone Aquifer System (NSAS)”. Groundwater-dependent springs, and their artificial counterpart “drilled wells”, are reliable water systems throughout the world. In the present study, hydrochemical parameters were collected in 2015 from 16 different springs and wells of the El-Farafra Oasis, and analyzed using the different water quality indices. The calculated water quality index (WQI), its correlations with the water quality parameters Gibbs, Piper, US Salinity-Lab Staff and Wilcox diagrams, and Principal Component Analysis (PCA) were used to evaluate the groundwater suitability for human drinking and irrigation purposes. WQI values revealed good-to-excellent groundwater quality for human drinking. In addition, the spring and well water samples investigated showed good indices for irrigation activities. Gibbs and Piper’s diagrams were presented, with most samples falling into the rock-dominance category, and belonging to hydrogeochemical facies determining the following water types: Mg(HCO3)2 type water (37.5% of the samples), no dominant ions (mixed water-type category; Ca/MgCl2) (50% of the samples), and, finally, NaCl water type (the remaining 12.5%). The groundwater chemistry in the study area is mainly controlled by rock-water interactions, particularly the dissolution of carbonate rocks and silicate weathering. The elevated nutrient concentrations, in particular nitrates, are most likely due to agricultural activities, indicating substantial anthropogenic activities in the area studied. Full article
