dc.description.abstractwork. vi ABSTRACT Surface water physico-chemical properties, periphytic and planktonic algae were sampled and analysed once a month for 24 months (January, 2013 to December 2014) in Tudun wada (TW), Makera (MK) drainages and a segment of River Kaduna in Kaduna metropolis, northern Nigeria using standard methods. The drainages which are modified by the deposition of solid and liquid wastes from urban residential areas, markets and industries transport such wastes downstream to River Kaduna, a major source of drinking water for the Kaduna town. Three sampling stations were selected along each drain (TW1, TW2, TW3, MK1, MK2 and MK3) to reflect the nature of pollution activities on the drain, while six stations were selected on River Kaduna (RK1, RK2, RK3, RK4, RK5, RK6), three associated with each drain- one point before the point each drain impacts the river, the second at the point each drain impacts the river and the third after each drain impacts the river. The values for surface water temperature (23.3 to 38.3°C), pH (6.12 to 10.79), electrical conductivity (EC) and total dissolved solids (TDS) (29 to 2253 μS/cm and 17 to 1125 ppm for EC and TDS respectively), total alkalinity (TA) (21 to 900 mg/L), sulphate (SO4) (1.30 to 225 mg/L) in surface water were observed to be significantly higher (P<0.05) on stations on the Makera drain (MK1, MK2 and MK3). While values for dissolved oxygen (DO) (0.10 to 4.16 mg/L), biochemical oxygen demand (BOD) (0.30 to 37.80 mg/L); total hardness (TH) (10 to 660 mg/L); nitrate-nitrogen (NO3-N) (0.17 to 14 mg/L); phosphate-phosphate, (0.1 to 2.30 mg/L); total nitrogen (TN), (17.80 to 70.72 mg/L); and total phosphorus (0.18 to 7.14 mg/L), were observed not to vary significantly among all the sampling stations (P≥0.05).
