“…The most dominant cations and anions of the groundwater and surface water were calcium (Ca 2+ ) and bicarbonate ions (HCO3-). Most of the samples were the Ca-HCO3, which represented typical shallow groundwater or clean streams (Figure 3) [26]. The next frequent type displayed in the Piper diagram is Ca-HCO3-Cl.…”

This study analyzed the hydrochemical characteristics and microbial communities of karst water in Samcheok, Korea, and compared water quality results to identify the seasonal characteristics and hydrogeological connectivity of the study areas of Hamaengbang-ri, Gyogok-ri, Yeosam-ri, and the downtown area of Samcheok. Field survey and water quality analysis were performed in July 2019, February 2020, and April 2020. Hydrochemical analysis of karst water (groundwater and surface water) showed that most samples were comprised of Ca-HCO3 and that water–rock interactions were a dominant factor compared to precipitation and evaporation (crystallization). For seasonal characteristics, water–rock interactions appeared more active in the dry season than in the rainy season. Calcite weathering was dominant in the dry season, whereas dolomite weathering dominated the rainy season. Moreover, the saturation indexes for the dry and rainy seasons were less than and greater than 0, respectively, corresponding to an unsaturation (oversaturation) state; thus, white precipitate distributed in the study areas was deposited in the rainy season. Finally, as a result of analyzing the hydraulic characteristics between regions, hydrogeological similarities were identified between Hamaengbang-ri and Yeosam-ri, and between Gyogok-ri and downtown Samcheok, which suggested hydrogeological connectivity between each of the pairs.

“…Moreover, the wetland also displayed Ca-HCO3-type properties, commonly observed in groundwater and surface water. Most of the Ca-HCO 3 types showed the properties of surface water, wetland, and shallow groundwater, which are directly affected by the atmosphere [32,33]. The Na-HCO 3 type showed the properties of deep groundwater samples [32].…”

Hydroecology of Argyroneta aquatica’s Habitat in Hantangang River Geopark, South Korea

The water spider (Argyroneta aquatic) is the only known spider to live a fully aquatic life. Therefore, it has been the subject of a series of studies on various aspects of its unique biology such as its reproductive behavior, sexual dimorphism, physiology, genetics, and silk. However, there have been relatively few studies on the hydroecology of where water spiders live. The water spider habitat in Eundae-ri, Yeoncheon is the only habitat for A. aquatica, a globally rare species, in South Korea. In this region, the water level of the wetland is automatically adjusted to groundwater owing to continued drying. Here, the surface water, wetland, and groundwater near the A. aquatica habitat were studied using hydrochemical, microbiological, and correlation analyses. The hydrochemical properties—water temperature, pH, electrical conductivity, dissolved oxygen (DO), oxidation reduction potential, and turbidity—of the surface water and wetland were similar. The Piper diagrams revealed that the wetlands, surface water, and most of the groundwater portrayed Ca-HCO3-type properties, whereas only areas where the water level of the wetland was controlled displayed Na-HCO3-type properties. Furthermore, the NO3 content was too low to be detected in the wetland, indicating clean and non-polluted water conditions; additionally, heavier oxygen-hydrogen isotopes were observed because these regions were climatically affected by the wetland. The dominant bacteria were Proteobacteria, Actinobacteria, Bacteroidetes, Cyanobacteria, Verrucomicrobia, and Nitrospirae. The correlation analysis revealed that the major environmental control factors of the A. aquatica habitat were DO, temperature, and pH, and the related bacteria were Cyanobacteria, Actinobacteria, and Verrucomicrobia.
