1. Since Bioremediation is based on natural attenuation the public considers it more acceptable than other technologies

2. Oxygen gas or ambient air can also be injected to promote growth of aerobic bacteria which accelerate natural attenuation of organic contaminants.

3. Bioremediation that involves natural attenuation or biostimulation is a publicly accepted treatment of polluted soil because it is based upon natural processes

4. There are three types of Bioremediation strategies involving microorganisms: 1) Natural attenuation – In some cases, natural populations adapt to the contaminant conditions and are able to convert the contaminants to non-hazardous endproducts rapidly enough to prevent
