What is the MCL for Total Trihalomethanes?

• A. 0.05 mg/L
• B. 0.02 mg/L
• C. 0.08 mg/L
• D. 0.10 mg/L

Answer: (C)

The Maximum Contaminant Level (MCL) for Total Trihalomethanes (TTHMs) is set at 0.08 mg/L. This regulatory standard is established by the Environmental Protection Agency (EPA) to protect public health from potential harmful effects associated with exposure to these disinfection byproducts, which can form when chlorine and organic matter react during the water treatment process. Maintaining TTHMs at or below this MCL helps minimize the risks of health effects, such as liver, kidney, or central nervous system problems, and potential cancer risks. Regular monitoring and control measures in drinking water systems are essential to ensure compliance with this standard, helping safeguard the health of communities.
