This study assessed the physico-chemical characteristics, concentration of heavy metals and nutrients composition of the surface water of Badagry and Tincan Island creeks adjoining the Lagos Lagoon. Sanplind was done once in a month between May and September 2019. The pH, Temperature, Salinity, Conductivity, Total Dissolved Solids, Total Suspended Solids, Dissolved Oxygen, Biochemical Oxygen Demand, Sulphate, Phosphate, Silicate, Nitrate, Calcium, Copper, Iron, Zinc, Lead, Cadmium, Manganese, Chromium and Nickel were determined usuing statndard methods. there was a significant difference (p<0.05) in the different parameters recocorded in the stations and the months. The DO (0.36 mg/L- 5.47mg/L) was lower than the WHO recommended 5mg/L for water quality assessment with a significant difference (p<0.05) recorded across the stations and months. The BOD values varied significantly across all the stations and the months with up to 211mg/L in station 1 in September thus depicting a severe deterioration of the creek. The concentrations of the heavy metals in the water samples were within the safe limit but posits potential human and fisheries health implications from continuous usage.
