In water quality standards, what does MCL stand for?

MCL stands for Maximum Contaminant Level, which refers to the highest permissible concentration of a contaminant in drinking water, as established by regulatory authorities. This standard is crucial because it helps to ensure that drinking water is safe for public consumption by limiting exposure to harmful substances. The MCL is set based on health effects, detection methods, and feasibility for water systems, making it a vital aspect of water quality regulations and protection. Understanding MCL is essential for water operators to effectively monitor and manage water quality in compliance with health standards and regulations.
