Abstract
This work present the results of determination of some pollutants and trace metals in
suspended solids, side-sediments and water from Zaria dam, which is the main water reservoir
from which Zaria metropolis, is being provided with pipe-borne water. Composite samples were
taken at different points in the dam, minimum of three composite samples were taken for each
month of sampling. Samples were taken in May, (before the rainy season) in August, (rainy
season) and in December (Dry season). Preliminary tests were carried out on all the samples and
AAS was used to determine metals concentration, other parameters were determined using
standard methods. The information from the data obtained was analyzed using statistical
methods. To access the physicochemical composition of the suspended solids, side-sediments
and water samples, descriptive statistical analyses were carried out and also a multivariate
analysis method of data analysis using Hierarchical Cluster Analysis (CA), Principal Component
Analysis (PCA). The samples taken in August, during the rainy season, show higher
concentration of trace metals for side-sediments, suspended solids, and water samples. Trace
metals in the suspended solids, side-sediments and water samples were found to be higher in the
order; Zn > Pb > Ni > Cr > Cd. From the multivariate analysis results, two components were
sufficient to explain the dam monitored. In the study, an attempt was made to determine factors
that could cause variation in water quality at the Zaria dam by using PCA. This result showed
that domestic waste, industrial waste and agricultural run-off during rainy season may be the
main cause for the variation in the water.
