[Occurrence of organochlorine compounds in drinking water for cities of Zielona Gora and in water of some rivers in the Zielona Gora province].
In years 1988-1989 the contents of organochlorine compounds were determined by gas chromatography in tap water obtained by treatment of a mixture of surface water and subterranean water, as well as in waters of three rivers of the Zielona Góra province Odra, Obra Leniwa and Obrzyca. Chloroform, carbon tetrachloride, trichloroethylene and tetrachloroethylene were determined. These compounds were present both in surface waters and subterranean waters. In subterranean waters the mean concentrations of chloroform and carbon tetrachloride were 12.3 and 2.7 micrograms/dm3, respectively. Surface waters contained from 10-20 to several tons of micrograms chloroform/dm3 and small amounts of carbon tetrachloride. The remaining organochlorine compounds occurred only in the Odra River, often in considerable amounts. During water treatment in accelerators, chloroform concentrations rose several times, and carbon tetrachloride levels slightly increased. In tap water the chloroform content fluctuated between 18.1-90.0 micrograms/dm3, whereas the concentration of the remaining organochlorine compounds did not exceed 5 micrograms/dm3.
