[Methods]At the year of 2004,collected the first section of water （ tap water ） from cast iron and chromeplate tap,examined the content of Fe,Zn, Mn, Cu, Pb, Cr^6＋ tone and opacity in Bin zhou urban areas. [Results]The first section＇s tone and opacity both higher than the middle section＇s of the two kinds of taps; The difference of the content of Mn,Cu,Pb,Cr^6＋ between the first section and middle section had no statistics sense of the two kinds of taps;The content of Fe, Zn in the first section distingiushed higher than the middle section of the two kinds of taps;The content of Fe,Zn in the first section of over night water was both minus with water yield of the two kinds of taps. [Conclusion]The tap＇s quality of material impact the tone,opacity and the content of Fe, Zn, it was suggested that sanitary and safe water supply pipe and tap should be applied.
