In this paper, an account for determination of chlorinated byproducts by High Performance Liquid Chromatography in various tap water samples is presented.The key objective of this study was to develop an analytical method for selectively and sensitively detecting the concentration of CBPs in addition to analyze selected parameters affecting CBP formation. Concentration of targeted compounds i.e. hydrazine sulfate, Dichloroacetic acid, Bromodichloromethane and chloroform were analyzed in tap water samples collected from a low socioeconomic area in a developing country. Hydrazine sulfate, Dichloroacetic acid and chloroform were detected in four water samples i.e. T4, T7, T9 and T10 while no samples contained Bromodichloromethane. Presence of these compounds in water is associated with cancer mortality and adverse reproductive outcomes.
