What is the Maximum Contaminant Level (MCL) for Total Trihalomethanes (TTHM) in drinking water?

• A. 0.040 mg/L
• B. 0.060 mg/L
• C. 0.080 mg/L
• D. 0.100 mg/L

Answer: (C)

The Maximum Contaminant Level (MCL) for Total Trihalomethanes (TTHM) in drinking water is set at 0.080 mg/L. This standard is established by regulatory agencies to help protect public health by limiting the amount of certain contaminants found in drinking water supplies. TTHMs are a group of four organic chemicals formed as byproducts when chlorine or other disinfectants are used to treat drinking water. These compounds can pose health risks when present above certain levels, leading to regulations aimed at controlling their concentration. The MCL of 0.080 mg/L is based on a balance between providing safe drinking water while still allowing water treatment facilities to effectively manage microbial pathogens. This level ensures that the risks associated with exposure to these compounds are minimized, thus safeguarding consumers' health. The regulation helps water treatment facilities implement proper monitoring and treatment protocols to keep TTHM levels below the limit, thereby ensuring the quality of drinking water. Other values listed do not reflect the current MCL for TTHMs, which is why they do not align with regulatory standards. Hence, understanding that the MCL is set at 0.080 mg/L is crucial for effective water treatment and safety protocols.
