Explanation:
Bioremediation is a process which occurs either naturally or is mechanically introduced to consume/breakdown the environmental pollutants to reduce the concentration of hazardous waste at a contaminated site. It is usually done in a non-sterile environment in such a way that the microorganisms which are introduced in it get adapted to the local ecosystem.
Some common application of bioremediation technology involves on- or off-site treatment at surface or in situ treatment.
