The Environmental Protection Agency (EPA) sets standards that, when combined with protecting ground water and surface water, are critical to ensuring safe drinking water. EPA works with its regional offices, states, tribes and its many partners to protect public health through implementing the Safe Drinking Water Act.
Primary Drinking Water Standards
Primary standards are legally enforceable regulations that protect drinking water quality by limiting the levels of specific contaminants that can adversely affect public health and are known or anticipated to occur in water.
Secondary Drinking Water Standards
Secondary standards are a guideline regarding contaminants that may cause cosmetic effects or aesthetic effects, but are not known to pose health risks.
For a list of the Primary and Secondary Drinking Water Standards and the FKAA’s most recent results please see the Water Quality Reports.
