Applications of Hydrochemical Models for Groundwater in Korea

Abstract

The variation patterns of groundwater mobility and chemical distribution are regarded as a very important factor for determining the geochemical features and therefore, the classifications of groundwater based on the chemical properties are highly valued for the expansion of study areas for setting up the regulations and management plans of governmental level for the preservation of local groundwater. Based on these prerequisites, in this study we focused on the evaluations, the comparison of the physiochemical characteristics and distribution of cations and anions in groundwater samples sampled in rural areas of Korea. The major goals of this study were classified as four categories such as followings; 1. On-site monitoring of groundwater qualities by instrumental and laboratory experiment, 2. Classifications of groundwater by using of Piper, Gibbs and Chadah diagram methods, 3. Tracking of the origins of anions and cations by using of rock-dominance types and relative ionic distributions. As a result of this study, the classifications of groundwater based on the Piper diagram showed that the groundwater type is grouped as the Ca In the applications of CAI 1 and CA 2, the negative values were more dominance than positive values so there might be reverse ion reaction between groundwater and rock-soils. Finally, by the carbonate weathering, silicate weathering and evaporation diagrams there were more complex mechanisms in chemical evolutions induced by the lithological influences such as weathering processes, ion exchange and other anthropogenic sources.

Characterization and Evaluation of Groundwater in Wadi Abu Gurdi, West Baranis area, South Eastern Desert Egypt: Geophysical and Hydrogeochemical Investigations

“…Groundwater samples fell between 1:2 (Ca 2+ +Mg 2+ = 0.5 TZ+) line and 1:1 equil-line in a scatter plot of Ca 2+ + Mg 2+ vs. total cations (TZ+) showing that some of these ions (Ca 2+ + Mg 2+ ) are came out from the weathering of silicate minerals (Fig. 9c) (Hwang et al, 2017). On groundwater chemistry, the important effect of silicate weathering could be specified by the bivariate schemes of Ca 2+ + Mg 2+ over HCO3 -+ SO4 2-.…”

Hydrogeochemical Assessment of Groundwater Quality and its Suitability for Irrigation and Domestic Purposes in Rural Areas, North of Baiji City-Iraq

“…Groundwater, which moves through aquifers, interacts with the aquifer material in the subsurface environment, leading to an alteration in its chemical composition due to a variety of hydro-geochemical processes. [2]. Generally, groundwater quality entirely depends on the physiochemical parameters present, which are mostly derived from geogenic and anthropogenic activities of a particular area.…”
