Seawater–freshwater mixing and resulting calcite dissolution: an example from a coastal alluvial aquifer in eastern South Korea

Abstract: In order to evaluate groundwater quality and geochemical reactions arising from mixing between seawater and dilute groundwater, we performed a hydrochemical investigation of alluvial groundwater in a limestone-rich coastal area of eastern South Korea. Two sites were chosen for comparison: an upstream site and a downstream site. Data of major ion chemistry and ratios of oxygen-hydrogen isotopes (δ 18 O, δD) revealed different major sources of groundwater salinity: recharge by sea-spray-affected precipitation in… Show more

“…Secondary porosity represents fracturing in the middle Miocene aquifer and is essential for groundwater flow. The seawater intruding into the coastal aquifer's carbonate increases their matrices' dissolution[16].The various vulnerability degrees of contamination and salinization in the El-Dabaa area refer to seawater intrusion, and groundwater over-pumping represent the main threats to the studied aquifers[17]. They (op.…”
