Abstract

The main hydrogeochemical characteristics of shallow groundwater in the coastal area at Kimje city, Korea, have been identified in the present study. From cluster analysis, the groundwater in the study area is classified into four groups (A, B, C, and D). Groundwaters in B, C, and D groups are strongly affected by the present seawater and the trapped old seawater because the area including B, C, and D groups contacts the Yellow Sea and contains the reclaimed land. They also are governed by reduction processes. On the other hand, groundwater in group A has been largely affected by chemical fertilizers because its land has been used for the agricultural activities for a long time. As groundwater flows from group A to group D according to its path, the governing factor of the groundwater quality gradually tends to change from chemical fertilizers into reduction processes and seawater intrusion.
