Aim of the Study: The research work attempt to answer the question; Do blue-green alga (Oscillatoria princeps) remediate petroleum polluted water?

Design/Methodology: The experiment is comprised of four treatments: Control (contaminated water only), Treatment A (5ml of contaminated water + 100ml of algae), Treatment B (5ml of contaminated water + 200ml of algae), and Treatment C (5ml of contaminated water + 300ml of algae). The treatments were allowed for 30 days. Classical Atomic Absorption Spectroscopy was used to analysis the physiochemical parameters.

Findings: The result shows that the pH of treatments A, B, and C increased by 152.62%, 154.25%, and 169.0%, respectively, when compared with the control, thereby making it alkaline, with a significant reduction in nitrate by 26.69%, 28.37%, and 49.0% for treatments A, B, and C, respectively. Nitrite was reduced by 10.0% and above for respective treatments. Total nitrogen reduced by 15.79%, 26.32%, and 50% for treatments A, B, and C. Iron reduced by 55.37%, 67.58%, and 83.79% for treatments A, B, and C. Manganese reduced by 47.43% for treatment A, then increased significantly by 173.20% and 237.53% for B and C. indicating that the microalgae did not degrade it. Lead showed a significant reduction up to 80.0% with treatment C. Cadmium also showed significant reductions of >50% for all treatments.

Practical Implications: Based on one of the Millennium Development Goals (MDGs) to ensure Environmental sustainability, this study proves that a petroleum contaminated water body can be remediated using a biological agent (Oscillatoria princeps) thereby improving water quality using an environmental friendly approach.

Originality/value: This study presents a massive contribution to nature being among the few studies carried out to remediate polluted water using biological agent thereby posing several benefits such as sustaining aquatic lives as well as reducing greenhouse gas emission from petroleum polluted areas.
