What does MCL stand for in water quality regulation?

MCL stands for Maximum Contaminant Level in water quality regulation. This term is important because it defines the highest permissible level of a contaminant that is allowed in drinking water, as established by regulatory agencies such as the Environmental Protection Agency (EPA). The establishment of MCLs is based on health risks and scientific research to ensure public safety and health. Setting these levels helps to protect water consumers from exposure to harmful substances in drinking water, ensuring a standard for water quality that utilities are required to meet. This is a critical aspect of maintaining safe drinking water standards for communities.
