Trichloroethylene (TCE) is a halocarbon with the formula C 2 HCl 3, commonly used as an industrial metal degreasing solvent. It is a clear, colourless, non-flammable, volatile liquid with a chloroform-like pleasant mild smell [3] and sweet taste. [9] Its IUPAC name is trichloroethene. Trichloroethylene has been sold under a variety of trade names.
Between 1975 and 1985, the water supply of Marine Corps Base Camp Lejeune was contaminated with trichloroethylene and other volatile organic compounds. [10]In 1986, and later again in 2009, 2 plumes containing trichloroethylene was found on Long Island, New York due to Northrop Grumman's Bethpage factories that worked in conjunction with the United States Navy during the 1930s and 1940s.
The agency also studied disposal practices for health care facilities where unused pharmaceuticals might be flushed rather than placed in solid waste, but did not develop wastewater regulations. [62] There are no national regulations covering disposal by consumers to sewage treatment plants (i.e., disposed down the drain).
Emmell's Septic Landfill (ESL) is a landfill in Galloway Township, New Jersey and takes up about 38 acres of space. The landfill was in operation from 1967 until 1979. ESL disposed of liquid and solid waste including many chemicals such as volatile organic compounds (VOCs), Polychlorinated Biphenyls (PCBs), Trichloroethene and Vinyl chloride which all had their own effect on the environment ...
Substitution of hazardous chemicals can be on different levels such as using: Less hazardous chemicals in the same process: For construction paints: from organic solvents to water-based paints, In printing industry for cleaning of printing machines: from organic solvents to products based on esters of vegetable oils, A new design of the process:
These typically run in the $100-$200 range plus the cost of installing a holding tank and an extra few bucks to chemically treat the waste for odor and bacteria.
At this site, microorganisms break down the carcinogenic compound trichloroethylene (TCE), which is a process seen in previous studies. [14] Bioremediation can be carried out by bacteria that are naturally present. In biostimulation, the population of these helpful bacteria can be increased by adding nutrients. [6] [15]
Many organochlorine compounds have been isolated from natural sources ranging from bacteria to humans. [3] [4] Chlorinated organic compounds are found in nearly every class of biomolecules and natural products including alkaloids, terpenes, amino acids, flavonoids, steroids, and fatty acids.
