520 | |b This study was aim to determine the effects of physicochemical properties and heavy metals level in tap drinking water samples collected from ten different locations on human health in Urban Katsina, Katsina State. Nigeria. A total of 20 (10 each) Tap water samples were collected during dry and wet seasons of the year 2013. The gross appearance, pH, EC, Turbidity, Hardness, Calcium (Ca), Chlorine (Cl) and the concentration of lead (Pb), Iron (Fe), Manganese (Mn), Zinc (Zn), Copper (Cu) were analyzed using standard analytical techniques. The results of analysis gave the physicochemical properties with range as follows: pH (5.3 — 7.7), conductivity (89 - 877 ohm/cm), turbidity (5 — 712 ntu), hardness (72 — 600 mg/l), Ca (0.2 - 18.75 mg/l) and Cl (-0.2 - 15.3 mg/l). The pH values were generally acidic while turbidity and hardness especially in most of the sampling locations were higher than the permissible levels set by the World Health Organization (WHO, 2004) for portable water. The concentration of heavy metals (mg/l) was found in the following ranges: Pb (0.04 - 0.3), Fe (0.04 - 0.44), Mn (0.05 - 1.48), Zn (0.03 - 0.19), and Cu (0.08 - 1.86). Lead and iron were detected in most of the Tap water samples and Manganese was detected only in one sampling location. Zinc and Copper, in all the two seasons, were within the maximum permitted levels of drinking water standard by SON (2007) and WHO (2004). Thus, all the tap water samples studied here are considered not safe for drinking from the Lead and Iron (some), i.e. have direct effects on human health. All these heavy metals detected in the tap water vary from one location to another. This could be associated with the leaching from rusting in the old galvanized metal pipe-work in the distribution channel. | ||
