摘要：Pure water samples were evaluated for their physicochemical properties. Samples 5 gave higher values of K(15 ppm), mg(6.75 ppm) and Zn (0.04 ppm). While sample 6 was high in P (4.85 ppm). The pH value of samples 8 (7.65) was also higher. Biochemical Oxygen Demand (B.O.D), Chemical Oxygen Demand (COD) and Total Suspended Matter were not detected in all the samples. However the total dissolved solids of sample 3 (0.012%) was very low. The colour of samples 1, 2, 4, 5, 7 and 8 are not significantly different from each other, while samples 3 and 6 are significantly different from each other. The taste of samples 2 and 5 were objectionable while the odours of samples (2-8) were objectionable. It is apparent from this study that the quality of the pure water samples could improve if a better water treatment is adopted.
