Answer :
Biosparging is the process of groundwater remediation as oxygen, and possible nutrients, is injected. When oxygen is injected, indigenous bacteria are stimulated to increase rate of degradation. However, biosparging focuses on saturated contaminated zones, specifically related to ground water remediation.
Any procedure where a living or dead biological system (usually bacteria, microalgae, fungus, and plants) is used to remove environmental contaminants from air, water, soil, flue gasses, industrial effluents, etc., in natural or artificial settings is referred to as bioremediation. The use of biological resources in the treatment of contaminated environments has gained popularity due to organisms' inherent capacity to adsorb, collect, and degrade common and developing contaminants. Bioremediation is scalable, affordable, sustainable, and environmentally friendly in contrast to traditional physiochemical treatment approaches, which have significant limitations. The majority of bioremediation is unintentional and involves native organisms. Research on bioremediation has a strong emphasis on accelerating the process by introducing organisms to a polluted site or providing nutrients to encourage the growth of organisms.
