Air Sparging FRTR

Some practitioners implement a variation of air sparging, referred to as biosparging, in which biodegradation rather than volatilization of contaminants becomes the primary removal mechanism (USACE, 2013). In practice, the term biosparging is frequently used to refer to air sparging systems when the intent is to operate without an SVE system.
