This study evaluated the water quality of untreated and treated water samples from Isiamaede stream and assessed the possible health implications following the consumption of the water samples using standard methods. The treated water sample was obtained with the help of locally purchased treatment agent. The pH values of untreated and treated water samples from Isiamaede stream were not within Nigerian Standard for Drinking Water Quality (NSDWQ) and World Health Organization (WHO) standards. pH value for untreated water sample of Isiamaede stream was more on the acid side (6.23) against that of treated sample with pH value of 6.44. Arsenic and lead metals were higher in the water samples against NSDWQ and WHO standards. Both samples were grossly polluted microbiologically with untreated water sample producing most of the dominant bacterial species isolated. The biochemical assessments revealed mild effect of the untreated and severe effect of the treated water samples from Isiamaede stream on rats. There is urgent need to inform the local population that depend on this stream and those that use the locally purchased treatment agent on the water appropriately. This study has evaluated the water quality of untreated and treated water samples from Isiamaede stream and assessed the possible health implications following the consumption of the water samples.
