Activated Carbon And Adsorption Of Trichloroethylene (TCE) And Tetrachloroethylene (PCE)Source: Jacobi Carbons Inc.
Trichloroethylene (TCE) and Tetrachloroethylene (PCE) are two of the most common solvents that contaminate groundwater supplies in the United States. Both solvents see frequent use in the extraction of fat, in the textile industry, in the production of various pharmaceutical and chemical products. TCE is also used as a degreaser from fabricated metal parts, and PCE serves as a component of aerosol dry-cleaning solvents.
Due to their widespread use, both TCE and PCE are often found in groundwater supplies. Due to their health and environmental impacts, USEPA has set a drinking water maximum contaminant level (MCL) of 5 parts per billion for each solvent.
