performance of the in situ air strip-
ping system, relative to conven-
tional cleanup technologies such
as soil vapor extraction and pump-
and-treat for the removal of VOCs,
has estimated that cleanup cost at
applicable sites could be reduced
by 50-60%. Assuming the tech-
nology is suitable at 10% of DOE sites, this represents potential cost savings of over $140 million. A
number
of innovative characteri-
zation technologies have been successfully transferred to the Sa-
vannah River Site (SRS) Environ-
mental Restoration and have been used at other SRS waste sites. At least 13
licenses for the in situ air stripping horizontal well patent have been granted
to or filed by commercial vendors. Licenses for the Sandia National Laboratory
(SNL) fluid flow sensor, Lawrence Livermore National Laboratory (LLNL) TCE sensor,
and Pacific Northwestern Laboratory (PNL) Halosnif sensor have been grant-
ed. The cone penetrometer fluor-
escence sensor has also recently
been patented. The use of
hori-
zontal wells for environ-mental applications has flourished over the last year
as a result of DOE's involvement in promoting this innovative technology.
