Abstract
The quality of drinking water in Zaria has been studied.
The treated water samples have been collected from different
public taps within Zaria and a tap outside the Ahmadu Bello
University (ABU) waterworks. In addition, raw water samples were
collected from both the Zaria and ABU dams. Chemical analyses
include the determinations of pH conductivity, residue (total,
filtrable and non-filtrable), chloride, fluoride, iodide and some
metals. Sodium and potassium have been determined by Flame
Photometry whereas calcium, magnesium, iron, zinc, copper, lead,
arsenic and mercury have been determined by Atomic Absorption
Spectrophotometry. The results have been compared with the
World health Organisation (WHO) standards. The parameters: pH
(except values for treated water from the ABU waterworks which
fell slightly outside the upper range), conductivity, residue,
chloride are present in ranges within the WHO specified limits.
Calcium, magnesium, iron, zinc and lead are also found to be
present in concentrations within the UHO specified limits
whereas copper, manganese, arsenic and mercury are found to be
absent in the water samples. Fluoride is found to be present
in both the raw and treated samples in concentrations higher
than the UHO standard. This makes the water unfit for consumption,
especially here in Nigeria where fluoride containing
toothpastes of unascertained fluoride contents are generally used and the fluoride contents of commonly ingested food
substances are not known. Iodide has been found in some cases
to be present in concentrations higher than the WHO standard.
