What does SMCL stand for in water quality regulations?

The term SMCL stands for Secondary Maximum Contaminant Level. This designation is used in water quality regulations to refer to non-enforceable guidelines established by the Environmental Protection Agency (EPA) for various contaminants that may affect the aesthetic qualities of drinking water, such as taste, odor, and color, rather than posing direct health risks.

Secondary Maximum Contaminant Levels are important as they help maintain the quality of drinking water without posing health hazards. These levels are set to address issues that may not necessarily render the water unsafe, but could affect consumer acceptance and satisfaction. By ensuring that these aesthetic parameters are adhered to, water utilities can provide a higher standard of service and public health assurance.
