Abstract

This study was performed to investigate the quality of spring water during the rainy periods in Mudeung mountain, in April, May, July and August 2010. The variation of physicochemical items such as pH, TDS,NO₃-N, Cl−, SO²_(4)− was not signigicant and the concentration at each sites satisfied with drinking water guideline except that of turbidity. The content variation of minerals like Ca^(2+), Mg^(2+), K^(+), Na^(+) showed generally stable during the rainy periods. Even though a photo catalyte sterilizer was used, total coliforms and fecal coliforms were detected in every sample collected, except for the one from Neutjae. That is why the sterilizing facility is exposed to many environmental variables such as insolation and rainfall. According to the distribution of species, at Jungmeorijae, total coliforms proliferate because of fecal contamination. However, at Neutjae, total coliforms were caused by plant, soil and water, rather than fecal.

Key Words: spring water, disinfection, photo catalyte sterilizer
