【 摘 要 】
Groundwater has different characteristics in each location influenced by mineral content in rocks that dissolves as water travels through the pores of rocks or soil or when stored in the soil (aquifer). Different minerals dissolving in rocks will lead to differences in anion content in groundwater. Chloride and bromide are the major ions that can be found in groundwater. The concentration of chloride is 500 times greater than the concentration of bromide. In addition, the high chloride concentration is a tracer for the influence of sea water. The ratio between chloride and bromide (Cl/Br ratio) can be used as a determinant of groundwater quality, as well as a determinant of groundwater contamination, sea water intrusion and the origin of sea water intrusion.
