Abstract

Samples were collected and measurements  taken and documented to analyse the physio-chemical status of  University of Abuja (mini campus) stream, University of Abuja teaching hospital stream, Gwako and Dobi streams for the period from July to August, 2015. The respective physical parameters of the four streams fell within the same range. Temperature values for the streams were (28.8°C ± 0.37, 28.6°C ± 0.26, 28.5°C ± 0.72, 28.3°C ±0.43), pH (6.0 ± 0.16, 5.9 ± 0.59, 5.8 ± 0.55, 6.2 ±0.24), Turbidity (42.60 cm ± 0.50 , 50.60 cm ± 0.43, 28.50 cm± 1.00, 28.30 cm ± 0.75) Transparency (29.65 cm ± 0.30, 28.80 cm ± 0.19, 36.58 cm± 2.08, 126.50 cm ± 4.22). The chemical parameters of the four stream are as followed sulphate ion was not detected in the University of Abuja (mini campus) stream, but was detected in the University of Abuja teaching hospital stream due to the habit of drainage waste dump and other human activities around the stream and was not detected in Gwako and Dobi stream due to the absence of drainage waste dump around the stream. Nitrate ion was not detected in the University of Abuja (mini campus) stream and Dobi stream but was detected in the University of Abuja teaching hospital stream and Gwako stream due to the human activities carried out around the stream. Chloride ion was detected in the University of Abuja teaching hospital stream, Gwako and Dobi stream but was not detected University of Abuja (mini campus) stream because no human activities is carried out around the stream. Calcium ion was detected in Dobi and Gwako stream because of the presence of rocks around the stream, but was not detected in the University of Abuja (mini campus) stream and the University of Abuja teaching hospital because of the absence of rock around the stream. All the values for the physical parameters fell within the WHO standard. Thus recommended for drinking, cooking and for food beverage industries except for the pH.
