| Abstract |
The characteristics of drinking groundwater at west Gyeong-nam were analyzed by investigating 3,698 cases which were carried out from January 2008 to september 2013. 24.5% of the observed data exceeded the drinking water quality standards. Among the drinking water quality standards, 40 parameters were found to exceed. and most problematic were total coliform and HPC(Heterotrophic Plate Count). The unfit ratio of each region for drinking water were 23.1% at Geoje, 18.7% at Geochang, 28.5% at Goseong, 24.1% at Namhae, 32.8% at Sacheon, 20.5% at Sancheong, 36.9% at Uiryeong, 29.2% at Jinju, 40.9% at Tongyeong, 24.7% at Hadong, 20.6.% at Hamyang, 20.1% at Hapcheon. The result of correlation showed that rainfall and unfit ratio of HPC may be associated with the hydrologic durability and season. The coefficient of correlation between them was 0.304. During the summer, the coefficient of correlation was 0.699. But the significant correlation between total coliform and rainfall was not found. |
