What does MCL stand for in water regulations?

• A. Maximum Contaminant Limit
• B. Maximum Contaminant Level
• C. Minimal Contaminant Level
• D. Contaminant Maximum Level

Answer: (B)

In drinking-water regulation, MCL stands for Maximum Contaminant Level—the highest amount of a contaminant that is allowed in water delivered to consumers. This is an enforceable standard set to protect public health while taking into account practical treatment and monitoring capabilities. The term uses “level” to emphasize a concentration value, and it is the official phrasing used in regulations and compliance. The other phrasings aren’t the standard regulatory terms. Understanding this distinction helps you read regulatory documents accurately and know what must not be exceeded in tap water.
