Abstract
The analysis of groundwater was carried out at 127 sites of Gwangju in 2005. The result of analysis for major anion contents showed chloride > sulfate > nitrate-nitrogen > fluoride and the one for major cation contents calcium > sodium > magnesium > potassium > ammonium. Correlation between the hardness of the groundwater and chloride, sulfate and total solids was carried out. Their correlation coefficients were 0.44, 0.30and 0.91, respectively. This correlation coefficients were similar to other regions such as Seoul, Gangwon and Incheon. A correlation coefficient was 0.62 between nitrate-nitrogen and chloride and was 0.35 between chloride and sulfate.
Key Words: Groundwater, Correlation coefficient, Gwangju
