Biodegradation is a forum for Scientists from all over the world to exchange ideas and to propagate the scientific knowledge. Bioventing which entails the use of soil vapor extraction (SVE) systems for the transport of oxygen to the subsurface, where indigenous microorganisms are stimulated to metabolize fuel components aerobically. These systems are designed to optimize transfer of oxygen and utilization efficiency which are operated at much lower flow rates and with configurations much different than those of conventional SVE systems. The applications of these bioventing systems design are contrasted to those of conventional SVE systems, and the two key elements of bioventing system design evaluation include in situ microbial activity and air permeability determinations.
