Information request:Technology in t

[Peter Strauss <pstrauss@igc.org>]

I'm looking for any information on the PURUS PADRE system, which is a 
resin based system used to capture vapors that come off of a soil vapor 
extraction system. It is an innovative technology that apparently has 
run into a few problems -- at a few sites where it is operating highly 
corrosive acids have formed, eating away at its insides. At a 
Superfund site that I am working at, the Air Force is planning to order 
several of these systems.
The first question I have is has there been any positive experience 
with these systems. Please get back to me if your site is using or 
contemplating using this system.
The second question I have is more general in nature. Apparently, the 
manufacturer has been losing money, and there is concern that it might 
go belly-up; or at the very least, may not be able to honor its 
warranty and technical support commitments. Does anyone have 
experience with a technology that is installed and the manufacturer 
cannot meet its commitments? How has that affected overall performance 
of cleanup? Are there conditions that the community should insist on 
before it gives its approval for such a technology? Any help or 
comments would be appreciated.

Thanks
