This study was examined occurrence of bisphenol A (BPA) and nonylphenol (NP) in waterworks system of Seoul, Korea from September 2002 to December 2003. The levels of BPA and NP in Han-river and its tributaries were as followed: Paldang-dam, ND(not detected)~0.033 ㎍/L and ND~0.823 ㎍/L; Kyungahn-creek, ND~0.659 ㎍/L and ND~3.827 ㎍/L; Whangsuk-creek, ND~0.528 ㎍/L and ND~12.724 ㎍/L, respectively. In water of 6 intake-station, the contents of NP and BPA were detected 0.122~2.724 ㎍/L, and ND~0.260 ㎍/L, respectively. In the finished- and tap-water of three drinking water treatment plants (DWTPs) around Whangsuk-creek, BPA was not detected in all samples, while NP was in ppt levels in whole. Through the process of DWTP, also, the removal ratio of NP was above 80% in all this. Therefore, this result was suggested that levels of BPA and NP in waterworkssystem depended on non-point contaminants and swage treatment plants in the Han-river shed.
