What is the MCL for Haloacetic Acids (HAA5s)?

The maximum contaminant level (MCL) for Haloacetic Acids (HAA5s) is indeed established at 0.060 parts per million (ppm). This regulation is designed to limit the concentration of these disinfection byproducts in drinking water, as elevated levels can pose health risks. The MCL is set based on health risk assessments and aims to protect public health by ensuring that drinking water maintains a safe level of these compounds, which can result from the chlorination of water supplies.

Other options present values that do not align with the established MCL for HAA5s, which highlights the importance of adhering to regulatory standards to safeguard against potential negative health effects associated with drinking water pollutants.
