Bioremediation is a process that utilizes living organisms, typically microorganisms, to break down and remove environmental contaminants from soil and water. One of the most recognized applications of this process is the cleanup of oil spills. In such incidents, specific microorganisms can be introduced to the contaminated area to degrade hydrocarbons present in the oil, transforming them into less harmful substances. This method not only helps restore the environment but is also often more cost-effective and sustainable compared to other cleanup methods.

In contrast, the other options do not reflect the nature of bioremediation. Soil excavation involves physically removing contaminated soil rather than using biological processes to treat it. The construction of waste containment facilities is focused on containing waste rather than treating it. Lastly, the installation of underground tanks pertains to the storage of fluids, which does not involve any bioremediation process. Therefore, the cleanup of oil spills using microorganisms is a definitive and common example of bioremediation in action.
