What is the maximum contaminant level (MCL) for haloacetic acids (HAA5)?

• A. 0.04 mg/L
• B. 0.06 mg/L
• C. 0.08 mg/L
• D. 0.1 mg/L

Answer: (B)

The maximum contaminant level (MCL) for haloacetic acids (HAA5) is set at 0.060 mg/L. This standard is established to protect public health by limiting the levels of these disinfection byproducts, which can form when chlorine or other disinfectants react with natural organic matter in water. The regulation is part of the efforts to ensure safe drinking water since elevated levels of HAA5 have been linked to potential health risks, including an increased risk of cancer. Meeting the MCL helps water treatment facilities manage the concentration of these compounds effectively and safeguard the wellbeing of consumers. Understanding this standard is crucial for water treatment professionals in maintaining compliance with federal regulations and ensuring the quality of potable water.
