The first of these types (primary) of contaminants are substances (examples could include Hg, As, and U) that can be toxic in small amounts. On the other hand, secondary contaminants are less toxic species (Fe and Zn) and would include cosmetic issues (color, taste, and odor) of drinking water. National Secondary Drinking Water Regulations (NSDWRs or secondary standards) are The EPA has established the National Primary Drinking Water Standards (NPDWRS) as a mandatory quality standard for the quality of our drinking water. These new regulations are legally enforceable, and they set Maximum Contaminant Levels (MCL’s) to ensure that the public is protected from using water that may be a health hazard. Under the SDWA, EPA sets the standards for drinking water quality and monitors states, local authorities, and water suppliers who enforce those standards. As part of the SDWA, EPA has set maximum contaminant levels, as well as treatment requirements for over 90 different contaminants external icon in public drinking water. However, EPA contaminant limits and drinking water secondary standards are guided by not only health effects and secondary water quality characteristics, but also the probability of detecting set species at a concentration that might be of concern.
EPA established to major types of contaminants: primary and secondary. The first of these types (primary) of contaminants are substances (examples could include Hg, As, and U) that can be toxic in small amounts.

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, odor, or color) in drinking water. EPA recommends secondary standards to water systems but does not require systems to comply.
