What are the bioremediation options?
Bioremediation companies use the natural ability of micro-organisms to degrade a wide range of organic contaminants. The microbes treat the contamination as a food source, and if oxygen is present (aerobic) they break it down to carbon dioxide and water. If oxygen is not present (anaerobic), they break it down to methane, carbon dioxide and hydrogen. Microbes cannot degrade inorganic contaminants, but they can be used to alter the contaminants in such a way that they become less harmful or are easier to remove from the soil/water. Bioremediation can be used to treat an increasingly wide range of contaminants and can be carried out ex-situ or in-situ. Ex-situ means excavating the soil or pumping out the groundwater before treatment, whereas in-situ means the soil/groundwater remains in the ground throughout the treatment. Why choose bioremediation? Bioremediation is an established technology that can reduce the risks associated with contaminated land and groundwater. There are many exam
