Greenpeace has found chemicals such as carbon tetrachloride, chloroform, trichloroethene
, tetrachloroethene, and dichlorobenzene, in concentrations ranging from five to 600 times the safety limits.
The starting point for this theory was their discovery in the south of Russia and South Africa that microbial processes in present-day salt lakes naturally produce and emit highly volatile halocarbons such as chloroform, trichloroethene
, and tetrachloroethene.
Elevated levels of dioxins, trichloroethene
, chromium, petroleum hydrocarbons and perchlorate have been found in the burn pit area, officials said.

Hundreds of sites across the United States contain trichloroethene
(TCE) contamination, including the Department of Energy's Savannah River Site (SRS) in Aiken, South Carolina.
Similarly, while DOE's pilot test of a new technology for removing the hazardous chemical trichloroethene
(TCE) from groundwater at the site had promising results--removing about 99 percent of the TCE in the test zone--the technology will not be fully implemented for more than a year.
The pesticide of greatest concern was aldicarb; the most common VOCs were tetrachloroethene (PCE), trichloroethene
(TCE), 1,1,1 trichloroethane (TCA), and 1,2 dichloropropane (DCP).
A plume of the solvent trichloroethene
(TCE) has spread under a section of downtown Orlando, where water below other properties also is being tested.
The specific objective, according to Craig Watson, a Senior Geo-Environmental Consultant with BAE Systems, was to achieve cost-effective, demonstrable reductions in trichloroethene
(TCE) concentrations, and to do so with minimal site disturbance.
Pollutant spectrum: trichloroethene
, tetrachloroethene, cis-1,2-dichloroethene, vinyl chloride, throughput: about 33 m 3 / h.
Subsequent soil and groundwater tests confirmed "extremely high levels" of trichloroethene

Among the contaminants are hexavalent chromium, trichloroethene
, chloroform, arsenic, nitrate, nitrite, uranium and methylene chloride.
