Public Health Guidelines & Water Quality Testing
WHS Drinking Water Guidelines & How We Protect Consumers
The health guidelines in the WHS Tap Water Database reflect the highest allowable concentration of a contaminant in water, as determined by scientific consensus for ensuring safety. These values are solely focused on safeguarding health and do not factor in the technical feasibility of the associated water treatment costs. This data table comprises health guidelines disseminated by either federal or state health and environmental agencies, or established by scientists.
