Oil Contamination in Urban Watersheds and its effect on River Ecosystem
Urban watershed are ecologically, culturally, and economically valuable resources. However, toxic chemicals and other pollutants that are stored, spilled, and discharged into the river and its tributaries threaten the watershed and impact human and ecological health. Crude oil spills from workshops; petrol and diesel pump stations during transportations, contaminates the soil with other contaminants. These contaminants make their way into the water through variety of pathways including through direct discharges into the river, runoff to rivers and streams, accidental spills, and seepage onto land and into groundwater. This permitted and non-permitted release poses risks to the river ecosystem and resources. Bioaccumulation and subsequent bio magnification causes health implications for humans who consume contaminated fish, shellfish, and other animals from the watershed. The paper reviews the toxicological effects of oil on key ecological resources, river system and on human health and suggests degradation of crude oil through process of bioremediation through case study.
