These days, Korean government expanded the national stream water quality tele-monitoring system and required each wastewater treatment facility to install a water quality tele-monitoring system at its discharge. Therefore, automatic water quality monitoring instruments and their principles of measurement (especially,ones for organic contents of a water sample) are attracting attentions from water quality scientists and engineers. To measure organic contents of water, total organic carbon (TOC), chemical oxygen demand (CODMn) and ultraviolet absorption (UVA) are often employed in automatic systems. In this study, TOC, CODMn, and UVA of water samples collected from different streams were compared and correlated. In short, these parameters showed relatively good correlation each other; R2s were 0.819~0.954 and 0.656~0.916 for TOCøÕ CODMn and UVA and CODMn, respectively. However, at low organic contents, these parameters were not strongly correlated.
