The ecological and economic significance of creeks is of global importance to coastal areas. These advantages
have been underutilized in many developing countries resulting in considerable pollution of its water ways. This study
investigates the degree of pollution of the Ebute Meta creek system Lagos, southwestern Nigeria. Surface water, ground
water, soil, sediment and plant samples were collected between the months of May and July 2011. Average surface water
DO (2.39±1.45 mg/L), BOD (167±53 mg/L), COD (329±106 mg/L), NO3
- (28.3±3.67 mg/L), NH3 (22.3±4.8 mg/L) and
(Pb 0.23±0.02 mg/L) levels indicated gross organic and metal pollution. Ground water similarly, showed elevated levels
of BOD (12.9±0.7 mg/L), nitrate (36.1±5.35 mg/L) and ammonia (13.7±2.6 mg/L). Metal levels in surface water and
sediment was strongly correlated (r=0.89). Topsoil and vegetation samples around the vicinity of the creek did not show
any significant level of contamination. There was no significant differences (p=0.05) in surface and ground water quality
among the sampling points. The creek water was classified as heavily polluted. This could affect the aquatic flora and
fauna of the creek ecosystem. Remediation measures should be employed to clean up the water way system and the
environment.
