post-treatment soil sample exceed 5.5 mg/Kg of PCE and the
average post-treatment PCE concentration across the site
be less than 0.56 mg/Kg. Over 3,100 lbs of VOCs and
another 9,000 lbs of other organic compounds were removed
between the pilot and full scale treatments. All

| TerraTherm conducted
a 6-well "micro-pilot" field demonstration of ISTD
treatment at a former industrial chemical landfill.
Contaminants consisted of a wide range of CVOCs, aliphatic
and aromatic hydrocarbons and heavy-end hydrocarbons
present as LNAPLs and DNAPLs, including chlorinated
ethyenes/ethanes, chlorinated benzenes and numerous heavy
aliphatics. The pilot test was designed to measure
the efficacy of thermal treatment at 100 deg C and 300 deg
C treatment temperatures and evaluate materials of
construction for the follow-on full-scale design and
implementation. TerraTherm provided heating and
effluent treatment equipment, as well as on-site oversight
of construction and the 3-month pilot test operation. |

of 11,100 m3. Approximately 2,350 kg of PCE was
removed over a 6-month period, with all project goals
met. The project included thermal treatment next to
a church, graveyard and residences. The site had
been the subject of a third-party Life Cycle Assessment
(LCA), which led to the selection of ISTD over excavation
or long-term SVE. The completed ISTD project took
less time, used less energy and cost less than the LCA
predicted. |
