Site Closures – Successful Projects Resulting In No Further Action

The list below includes sites treated with the Cool-Ox™ technology where contaminant levels were reduced to the point that the regulatory agency required no further remedial action. DTI can be contacted for details.

California
Industrial site: stiff clay over wet water-bearing clay zone – groundwater – Vertical         injection Interval (VI) = 12 to 22 fbgs (feet below ground surface),vinyl chloride, DCE,        TCE

Wood treating site: alluvial sediment, gravel - soil and groundwater – VI = pit and 3 to 15 fbgs, pentachlorophenol (PCP), mineral spirits

Illinois
Former fueling site: stiff clay - soil and groundwater, BTEX, GRO – VI = 2 to 12 fbgs

Former service station: sand - soil and groundwater, BTEX – VI = 3 to 12 fbgs

Active rail yard: track ballast and road base, PAH (benzo(a)pyrene) – VI = 0 to 3 fbgs

Indiana
Industrial site: tight clay - soil and groundwater, vinyl chloride, DCE, BTEX – VI = 2 to 12 fbgs

Active rail yard: tight clay - Soil, Silvex, 2, 4, D - 2, 4, DP - 2, 4, 5, T – VI = 0 to 8 fbgs

New Jersey
Industrial site: clay and backfill debris - groundwater, Mixed plume – toluene, TCE – VI    = 2 to 12 fbgs

New Mexico
Kirkland Air Force Base: clay and sand - soil, JP-5 – TPH, PAH – VI = 10 to 55 fbgs

South Carolina
Pipeline release: sand – soil and groundwater, naphthalene – VI = 2 to 10 fbgs

Wisconsin
Basement of commercial building: sand - soil, fuel oil, PAH – 0 to 18 ft below the        basement floor

Closure Standards Achieved – Sites Awaiting Other Activities

The list below includes those sites that have been treated with the Cool-Ox™ technology where the contaminant concentrations have been reduced to closure levels. However, a no further action notice from the regulatory agency is still pending due to on-site circumstances unrelated to the Cool-Ox™ process or DTI’s activities. DTI would be happy to provide more details about these projects!

Colorado
Dry cleaner:  siltstone/claystone, clay – soil, DNAPL, PERC – VI = 5 to 20 fbgs

Michigan
Barge Terminal: sand - soil and groundwater, free product (benzene) – VI = 2 to 12 fbgs

Florida
Marine Terminal: > 50,000 square feet: sand - soil and groundwater, free product (TRPH, toluene)

Illinois
Barge Terminal: sand and rail ballast, MIBK, styrene monomer – VI = 0 to 12 fbgs

Wisconsin
Industrial site:  card clay, PERC (6,400 ppm) and machine oils – VI = 2 to 14 fbgs

Industrial site:  hard clay and fill, PERC – VI = 0 to 10 fbgs

Cool-Ox™ Injections Resulting In
Reductions Meeting State Post-Remedial Monitoring Criteria

DTI has treated more than twenty-five (25) sites in Florida with the Cool-Ox™ technology. Of these, DTI detected free product at seven (7) sites and slated them for further injection. The remaining eighteen (18) sites exhibited such dramatic reductions in contaminant levels, that the Florida Department Of Environmental Protection (FDEP) placed them in the Post Remedial Monitoring Program toward natural attenuation. DTI would be happy to provide more details on these projects!
