"Ten raw urban well water samples and twelve water samples collected from distribution lines after the well waters were treated were examined for bacteriological and coliphage/bacteriophage populations. The raw well waters were found to contain <1/100 mL total coliforms and fecal streptococci, but they all contained varying concentration of coliphage and bacteriophage. The treated waters all were found to have <1 total coliforms and fecal streptococci/100 mL with the exception of one treated water sample from Community C. However, even though the treated water samples contained free and total chlorine levels varying from 0.05 to 1.5 ppm, they all were found to contain usually greater amounts of coliphage and bacteriophage than the raw well waters. Details of the study and implications are discussed"--Abstract. Includes abstract and management perspective in English and French. gccst Groundwater gccst Pollutants gccst Analysis Palmateer, G.
