What is the Maximum Contaminant Level (MCL) for Haloacetic Acids (HAA5) in drinking water?

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

Answer: (B)

The Maximum Contaminant Level (MCL) for Haloacetic Acids (HAA5) in drinking water is set at 0.060 mg/L. This standard is established by the Environmental Protection Agency (EPA) to protect public health, as HAA5 are byproducts formed during the disinfection process using chlorine and other disinfectants. Consistently exceeding this level can pose health risks, including potential links to cancer with long-term exposure. The regulation aims to minimize these risks while ensuring that drinking water remains safe for consumption. This level reflects a balance between preventing adverse health effects and the practicalities of water treatment practices.
