Variation of Hydrochemical Characteristics of Major Elements in Groundwater by the Seawater Intrusion in the Byeonsan Peninsular, Korea
Forty five groundwater samples and a seawater sample in Wido island and Byeonsan peninsular, Korea were collected and analyzed to evaluate the variation of geochemical characteristics. The status of seawater intrusion, whether it is on ion-exchange stage or on mixing stage was determined, using the ratios between major cations(Ca2+/Na+and Ca2+/Mg2+). These ratios of some groundwaters which has been intruded by seawater continuously are approximately same to those of seawater. The contents of major cations in groundwaters of coastal region change due to the ion-exchange reaction on mineral surfaces and mixing reaction. Ca2+- Na+ and Ca2+-Mg2+ ion-exchanges are inferred to be the most probable reactions. It was calculated that the mixing ratio of seawater in the studied area has been reached up to 10%. A well resampled after one year lapse without pumping showed the composition recovered from the early mixing stage to the ion-exchange stage, which may suggest the possibility of the remediation of groundwater by balancing the pumping rate with the precipitation.
