WebBioremediation uses microorganisms to degrade organic contaminants in soil, groundwater, sludge, and solids. The microorganisms break down contaminants by using them as an energy source or cometabolizing them with an energy source. More specifically, bioremediation involves the production of energy in a redox reaction within microbial cells. Webbioremediation”, “passive bioremediation”, “natural recovery”, and “natural assimilation”. Note, however, that none of these are necessarily equivalent to MNA. MNA is often dubbed “passive” remediation because natural attenuation processes occur without human intervention to a varying degree at all sites.
