RE: Feedback requested on DNAPLs

In a response to a request by Susan Gawarecki, a question was asked about
insitu oxidation methods.  Bioventing was mentioned as an example of this
process.  Bioventing is a technique used for the vadose zone and is probably
not applicable to DNAPL-type chemicals and situations.  At the Waterloo
course, three techniques were discussed:  hydrogen peroxide; potassium
permanganate and enhanced biodegradation.  Most of the research at Waterloo
is related to the last two technologies.  Both of these techniques attack
the DNAPL directly.  While these technologies are not instant removed all of
the DNAPL solutions, they appear to be quite effective as they completely
destroy the DNAPL chemicals.  As with any potential treatment of a DNAPL
source, the source needs to be isolated from the aquifer.
