Benzene is a toxic chemical that can contaminate drinking water sources through various sources, including industrial activities, gasoline spills, and natural processes. Exposure to benzene can cause a range of health effects, including cancer, anemia, and immune system damage.
The U.S. Environmental Protection Agency (EPA) has established a maximum contaminant level (MCL) of 0.005 milligrams per liter (mg/L) for benzene in drinking water. Public water systems are required to monitor for benzene and take action if levels exceed the MCL.
Treatment technologies for removing benzene from drinking water include activated carbon adsorption, air stripping, and biological treatment. The effectiveness of these technologies can depend on factors such as the concentration of benzene, the characteristics of the water source, and the treatment system design.
