In addition to the primary standards, the EPA has established national Secondary Drinking Water Regulations that set non-mandatory water quality standards for 15 contaminants. The EPA does not enforce these "secondary maximum contaminant levels" (SMCLs). They are established as guidelines to assist public water systems in managing their drinking water for aesthetic considerations, such as taste, color, and odor. They are sometimes referred to as "nuisance" impurities. *Defined here: What is

9 No more than 5.0% samples total coliform-positive in a month. (For water systems that collect fewer than 40 routine samples per month, no more than one sample can be total coliform-positive). Every sample that has total coliforms must be analyzed for fecal coliforms. There cannot be any fecal coliforms.

While primary standards are federal-level, legally binding mandates focused entirely on the public’s health, secondary standards are meant to zoom outward, taking a broader look at what makes public drinking The US national Primary Drinking Water Regulations establish standards for water purity that apply to public water systems.*. The standards define a permitted "maximum contaminant level" (MCL) for various minerals, chemicals and other pollutants that has been arrived at by weighing health risks, expected exposure, technical feasibility of treatment, and other cost-benefit analyses. Under the SDWA, EPA sets the standards for drinking water quality and monitors states, local authorities, and water suppliers who enforce those standards.

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.
