摘要

The study investigated quality of water sources (had-dug well, borehole and pipe-borne water) in Jushi Waje, Zaria, Nigeria. A total of thirty six samples were collected among the three sources in twelve (12) locations during dry season, 2014 using the stratified systematic random method. The samples were collected and physicochemical parameters (pH, Electrical conductivity (EC), turbidity, Total Solid (TS), Total Dissolved Solid (TDS), Dissolved Oxygen (DO), Biochemical Oxygen Demand (BOD), phosphate, chloride, sulphide, free chlorine and nitrate) were analysed using standard methods (APHA). The results showed; pH ranged from 5.2 to 6.8, 5.2 to 6.1 and 6.4; EC ranged from 3.38 to 7.42,3.37 to 5.03, and 1423μS/cm, while turbidity ranged from 0.3 to 21.0, 0.6 to 6.8 and 11 NTU for well, borehole and tap water, respectively. On the other hand, TS was in the order of 2.81 to 21.71,3.41 to 1717 and 701 mg/L; and TDS value ranged between 2.5 to 1744,2.64 to 1736 and 706 mg/L, respectively for well, borehole and tap water samples. For other parameter, the well, borehole and tap water exhibited DO (0.55 - 0.95, 0.68 - 1.67 and 1.5, mg/L), BOD (0.2 - 27.5, 5.6 - 17.2, and 8.2 mg/L) phosphate (1.3 - 7.7, 0.5 - 4.5, and 1.2 mg/L) chloride (98.3 - 189.0,67.8 -167, and 29.2 mg/L), sulphide (0.03 - 0.41,0.015 - 0.100, and 0.013mg/L), free chlorine (0.01 - 0.29,0.021 - 0.05, and 0.03mg/l) and nitrate (0.6 -7.20, 0.23 - 3.40, and 5.2 mg/L), respectively. The values of pH, TS, TDS and phosphate in majority of the samples especially for the well and borehole water exceeded the maximum permissible limits. The results showed that water from well and borehole within the study area were contaminated and deem unfit for drinking, and may constitute health risk in the long term.
