Drinking water is vital for life existence worldwide which is used on a daily basis. The quality of this drinking water however varies from one product to another. In this study, analysis of four heavy metals: Zn, Cu, Cd, and Pb were done by AAS technique in four water samples; Tap water, Well water, Faro bottle water and KSUSTA table water. The results of the study showed that Pb was not detected in the Tap, Well, and Faro Bottle water samples but was however detected in the KSUSTA Table water sample (0.954 mg/L) well above the limits of USEPA (0.015 mg/L), WHO (0.01 mg/L), and SON (0.01 mg/L) respectively. Also, the Well Water sample did not contain Cd, but was detected in the other three samples well above the standard limits. Cu was detected in all the samples below the limits by the regulatory bodies. The KSUSTA Table Water did not contain Zn while the other three water samples had Zn levels below the max limits. Hence, the Well water sample was shown to be the best or safer for consumption as it did not contain any Pb or Cd concentration and had Cu and Zn levels below the permissible limits by these agencies. Therefore, those consuming KSUSTA Table water, Faro Bottle water and Tap water in Aliero town should be cautious of the potential danger from the short or long term effect of Pb and Cd toxicity to the human body.
