A total of
8 samples were collected from strategic points along the
Ugborikoko/Okere creek. The levels of the physico-chemical
parameters and heavy metal pollutants were determined.
Results of both physico-chemical characteristics and heavy
metals revealed some degree of pollution in the creek. The
mean values of pH, temperature, turbidity, conductivity,
total dissolved solids, total suspended solids and chloride
were 6.8, 30.3°C,
106.53 NTU, 471.45 ohms/cm, 354.56 mg/l, 123.56 mg/l and
78.11 mg/l respectively. The average value obtained for oil
and grease was 14.13 ppm. The average value for the heavy
metals were 2.258 ppm for iron, 0.0729 ppm for cadmium,
0.4225 ppm for zinc, 0.0997 ppm for manganese, 0.0236 ppm
for copper, 0.2117 ppm for nickel. The results obtained
indicated a significant level of pollution of the Ugborikoko/Okere
creek. It was observed that the levels of iron, lead,
chromium, cadmium, manganese and nickel in the samples were
not in compliance with recommended standards set by world
health organization for inland (fresh) and potable water.
