What does MCL stand for in water regulation terms?

MCL stands for Maximum Contaminant Level, which is an important standard set by regulatory agencies, such as the Environmental Protection Agency (EPA), to ensure safe drinking water. It represents the highest permissible concentration of a contaminant in drinking water that is allowed under the Safe Drinking Water Act. The determination of MCLs is based on health risks and the feasibility of water treatment technologies.

Regulatory bodies establish these levels to protect public health from the harmful effects of contaminants that can arise from various sources, such as agricultural runoff, industrial discharges, or naturally occurring substances. By adhering to these standards, water suppliers can provide safe drinking water to the community, minimizing health risks associated with exposure to pollutants. Thus, understanding MCLs is essential for water operators as they work to monitor and treat water supplies effectively.
