Dec 14, 2017 · 1,2,3- TCP is a chlorinated hydrocarbon with high chemical stability. It is a manmade chemical found at industrial or hazardous waste sites. It has been used as a cleaning and degreasing solvent and also is associated with pesticide products.

1,2,3-Trichloropropane (TCP) is an organic compound with the formula CHCl(CH 2 Cl) 2. It is a colorless liquid that is used as a solvent and in other specialty applications. [3]

TCP is a regulated organic chemical in public water systems requiring monitoring and reporting to the SWRCB, starting in January 2018. The notification level was established at 0.005 μg/L in 1999. Analytical methods to meet the notification level were established in 2002.

• 1,2,3-TCP is a potent mutagenic carcinogen. –It caused tumors at multiple sites beginning early in life in both sexes of two species of rodents. • The basis and numerical value of the cancer potency factors developed by DWQI (March 2009) and USEPA IRIS (September 2009) are in close agreement.

Dec 28, 2017 · This fact sheet, developed by the U.S. Environmental Protection Agency (EPA) Federal Facilities Restoration and Reuse Office (FFRRO), provides a brief summary of the contaminant 1,2,3-trichloropropane (TCP), including physical and chemical properties; environmental and health impacts; existing federal and state guidelines; detection and ...

On December 14, 2017, the California Water Resources Control Board Division of Drinking Water (DDW) adopted a regulation promulgating a Maximum Contaminant Level (MCL) for 1,2,3-trichloropropane (1,2,3-TCP) of 0.000005 milligrams per liter (mg/L, or 5 parts per trillion or 5 ppt).

TCP is a contaminant of interest to the government, private sector and other parties. It is a persistent pollutant in groundwater and has been classified as “likely to be carcinogenic to humans” by the EPA. What is TCP? TCP is a chlorinated hydrocarbon with high chemical stability (Samin and Janssen 2012).

1,2,3-Trichloropropane, also known as TCP, is an organic chemical found in some groundwater supplies. In July 2017, the State Water Resources Control Board approved the maximum contaminant level (MCL) for TCP of 5 parts per trillion (ppt), …

This fact sheet is intended for use by site managers and other field personnel in addressing TCP contamination at cleanup sites or in drinking water supplies and for those in a position to consider whether TCP should be added to the analytical suite for site investigations.

TCP is a contaminant of interest to the government, private sector and other parties. It is a persistent pollutant in groundwater and has been classified as “likely to be carcinogenic to humans” by EPA (EPA 2009). What is TCP? TCP is exclusively a man-made chlorinated hydrocarbon, typically
