The Agency sets regulatory limits for the amounts of certain contaminants in water provided by public water systems. Additionally, the EPA also adheres to scheduled water-testing and methods that water systems must follow. The Safe Drinking Water Act gives each individual state the opportunity to set their own standards for drinking water, as long as they are as stringent or more so than the national standards set by the EPA. Secondary Drinking Water standards, or Secondary Maximum Contaminant Levels (SMCLs), are concentration limits for nuisance contaminants and physical problems, such as offensive taste, color, odor, corrosivity, foaming, and staining. The Secondary Standards are not enforced, ----- National Secondary Drinking Water Regulation National Secondary Drinking Water Regulations are non-enforceable guidelines regarding contaminants that may cause cosmetic effects (such as skin or tooth discoloration) or aes- thetic effects (such as taste, odor, or color) in drinking water. EPA recommends secondary standards to water systems However, EPA also has established National Secondary Drinking Water Regulations that set non-mandatory water quality standards (secondary maximum contaminant levels or SMCLs) that are used as guidelines to assist water systems with managing drinking water for aesthetic considerations, such as taste, color, and odor.
