Trichloroethylene (TCE) is a volatile organic compound that has been widely used as a dry-cleaning solvent and degreasing compound. It is known to have contaminated groundwater and is now found in trace amounts in many parts of the world. Methane, benzene, and formic acid are also volatile organic compounds, but they are not commonly used as dry-cleaning solvents or degreasing compounds, and they are not as commonly found in contaminated groundwater as TCE.
