What is the MCL for bromate?

What is the MCL for bromate?

• A. 0.005 ppm
• B. 0.01 ppm
• C. 0.02 ppm
• D. 0.03 ppm

Answer: (B)

The maximum contaminant level (MCL) for bromate is set at 0.01 parts per million (ppm). This regulatory standard is established to protect public health by limiting the concentration of bromate, which can form as a byproduct during water disinfection processes, particularly when ozone is used as a disinfectant. High levels of bromate in drinking water have been associated with potential health risks, including an increased risk of cancer. Therefore, the MCL ensures that any water supply that meets this standard maintains safety for human consumption, making 0.01 ppm the correct and recognized limit for bromate in drinking water. Understanding the significance of this level helps water operators manage their systems in compliance with regulatory standards to safeguard public health.
