Abstract:
: The water we drink is essential as it plays vital role in our welfare and healthy life.
Heavy metals make our water unsafe. This study seeks to evaluate Heavy Metals Concentration
and Water Quality in Malali Water work, Kaduna. Using standard procedures, heavy metals
concentrations were determined. Significant difference in monthly concentrations was observed
of nickel in the raw water samples. The values obtained ranged between 0.053 and 0.742 mg/L.
Data obtained for Ni in raw water samples were seen to be higher than permissible limits set by
the WHO (0.02 mg/L) and NSDWQ (0.07 mg/L). Chromium concentrations in raw water
samples were between 0.0098mg/L (January) and 0.073 mg/L (July), with the monthly mean
values presents significant differences. Significant differences were also observed in
concentrations of copper in raw water samples with the values ranging between 0.57±0.54 mg/L
(January) and 1.658±0.05 mg/L (September) and the values were within the NSDWQ
permissible limit of 2 mg/L. although lead and other heavy metals are poisonous at certain level,
their presence in water may be that contaminants may have been washed into the water body.
Common sources of pollution in water include household paint, Lead batteries, fertilizers, and
metal based-pesticides. In conclusion, Heavy metal content in treated water were generally
within permissible range presented by WHO and NSDWQ, except iron concentration that was
beyond permissible limits presented by WHO.
