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.
In 1982, the Marine Corps discovered volatile organic compounds (VOCs) in several drinking water wells that fed into two of the eight water systems. The sources were traced to tetrachloroethylene (PCE) from a two dry cleaners – one on base, the other off the base and trichloroethylene which had been used in vehicle maintenance on the base ...
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.
Groundwater, surface water and sludge contamination by VOCs (including TCE and DCE); residential wells contaminated by arsenic. Soil contamination by PCBs and metals. Groundwater contamination is currently contained on-site.
In 1980, two volatile organic compounds (VOCs), trichloroethylene (TCE) and tetrachloroethylene (PCE) were discovered at the Newmark well fields. [1] Exposure to PCE and TCE is associated with adverse health effects such as Central Nervous System depression, neurological, lung, kidney, and heart effects, and increased cancer risk.
Volatile organic compounds (VOCs), including benzene, perchloroethylene (PCE), trichloroethylene (TCE), toluene, vinyl chloride, xylene, and heavy metals, including arsenic, barium, cadmium, chromium, and lead have been detected in on-site soil and residential and industrial wells.
FMC site groundwater is contaminated with volatile organic compounds (VOCs) including trichloroethylene (TCE). Soil that was excavated in the 1980s was also contaminated with TCE. The main health risk at the FMC site would be if someone were to use contaminated groundwater as a drinking water supply.
Due to its classification as VOC exempt, dimethyl carbonate has grown in popularity and applications as a replacement for methyl ethyl ketone (MEK) and other solvents. tert-Butyl acetate is used as a solvent in the production of lacquers, enamels, inks, adhesives, thinners and industrial cleaners. [10] [11] It also gained EPA VOC exempt status.
