Abstract

The analysis of raw water and purified water from 105 social welfare organizations in Gwangju was performed to find out the purification effect of water purifiers in use. In the study, 105 purified water samples and corresponding raw water samples (95 from tap water, 10 from groundwater) were analyzed. Forty six inspection items of drinking water standard and main minerals (Ca2+, Mg2+, K+, Na+) were analyzed for groundwater and 28 items such as heavy metals, microorganisms, disinfection by-products, aesthetic materials were analyzed for tap water. When the concentration of each item in purified water showed lower than that of raw water,we expressed the results as the positive(+) effect and vice verse, negative(-) effect. The results of the purification effect of water purifier using tap water and groundwater were presented (+) effect 39.6% and (-) effect 28.0%, (+) effect 39.1% and (-) effect 30.1%, respectively
