What MCL is assigned to Haloacetic Acids (HAA5) in drinking water?

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

Answer: (C)

The maximum contaminant level (MCL) for Haloacetic Acids (HAA5) in drinking water is set at 0.060 mg/L. This regulation is crucial for public health because HAA5, which are disinfection byproducts formed when chlorine used for water disinfection reacts with organic matter in the water, are associated with several health risks, including potential carcinogenic effects. The establishment of this specific MCL aims to limit exposure to these compounds and ensure safe drinking water levels for the population. Regulatory agencies continually evaluate and revise MCLs based on the latest research and health assessments to keep drinking water safe.
