Abstract
This paper presents the result of groundwater analysis in Changwon area and the characteristics of the groundwater properties. Changwon city conducted groundwater analysis at 551 sites in 1996 and 1997. The water quality is suitable as groundwater use at 466 sites (84.6 %) and exceeds maximum contaminant levels (MCLs) at 85 sites (15.4 %). Major contaminants are total bacteria, coliform and nitrate-N. DNAPLs, e.g. TCE and PCE are detected in the areas of industrial complex and residence. The detection of TCE and PCE is due to organic solvents from manufacturing companies. They are also derived from laundries, Photographer's studios, septic tanks, etc. In addition, fifty groundwater samples were analyzed. Iron, manganese, zinc, copper, lead, aluminum and fluorine are detected in nearly all the groundwater samples. The groundwaters shown on the Piper diagram mostly belong to Ca-HCO
