초록
This study was performed to investigate the water quality of non-designated spring in Gwangju. Samples were collected at 9 sites from April 2012 to March 2013. The average concentrations of physicochemical items at each sites satisfied with drinking water guideline except microorganisms. The concentrations of main minerals including Ca2+, Mg2+, K+ and Na+ showed generally similar and higher than those of bottled minerals water in some sites. Total coliforms and fecal coliforms were detected in some sample collected except S1 and S4 site. The microorganisms isolated in the natural mineral water found out E. coli (62%), Raoultella planticola (10%), Citrobacter freundii (9%) and so on. Detection of these microorganisms showed that the environment around the spring had been exposed to fecal contamination. For the efficient control, the government office needs to designate the S1 and S4 site found out the acceptance for drinking water standard as the management spring water.
