Article Abstract
The fungal distribution, diversity, and load were analyzed in the geographically segregated island groundwater systems in Korea. A total of 79 fungal isolates were secured from seven islands and identified based on the internal transcribed spacer (ITS) sequences. They belonged to three phyla (Ascomycota, Basidiomycota, and Chlorophyta), five classes, sixteen orders, twenty-two families, and thirty-one genera. The dominant phylum was Ascomycota (91.1%), with most fungi belonging to the (21.5%), (15.2%), and (8.9%) genera. showed higher dominance and diversity, being widely distributed throughout the geographically segregated groundwater systems. Based on the diversity indices, the genera richness (4.821) and diversity (2.550) were the highest in the groundwater system of the largest scale. As turbidity (0.064-0.462) increased, the overall fungal count increased and the residual chlorine (0.089-0.308) had low relevance compared with the total count and fungal diversity. showed normal mycelial growth in de-chlorinated sterilized samples. Overall, if turbidity increases under higher fungal diversity, bio-deterioration in groundwater-supplying facilities and public health problems could be intensified, regardless of chlorine treatment. In addition to fungal indicators and analyzing methods, physical hydrostatic treatment is necessary for monitoring and controlling fungal contamination.

Groundwater overextraction presents persistent challenges due to strategic interdependence among decentralized users. While game-theoretic models have advanced the analysis of individual incentives and collective outcomes, most frameworks assume fully rational agents and neglect the role of cognitive and social factors. This study proposes a coupled model that integrates opinion dynamics with a differential game of groundwater extraction, capturing the interaction between institutional authority and evolving stakeholder preferences.

Evaluating groundwater infiltration (GWI) in sewer networks is essential for managing network capacities, especially amid growing pressures on network maintenance and operation caused by increasing domestic and storm water inputs. Despite this significance, GWI assessments have received limited attention, especially at large scales. In fact, no previous study has comprehensively evaluated sewersheds based on GWI scores.

Oligotrophic groundwater limits biodegradation in sand filtration, illuminating the pathway of the in-situ production of oxidatively active Mn oxide (MnOx) to remove emerging contaminants (ECs). Based on the Mn(II) removal filter, increased production of chemical MnOx (CheMnOx) for EC removal could be realized by increasing biogenic MnOx (BioMnOx) as the Mn active film to stimulate autocatalytic Mn(II) oxidation. However, progress in exogenously enhancing biogenic Mn(II) oxidation is limited.

Large-scale underground coal mining alters regional water cycles, yet the mechanisms governing interactions among water bodies in deep mining areas are poorly understood. For this purpose, by integrating hydrogen and oxygen isotopes, water levels, hydrogeological conditions, and end-member mixing analysis (EMMA), this study systematically analyzed and quantified the circulation and transformation mechanisms among different water bodies influenced by coal mining. Key findings reveal: (1) Mining-induced fractures disrupt the aquitard above the coal seam, establishing a direct hydraulic link between Zhiluo Formation confined groundwater and mine water, with the former contributing 87.
