Definitions for "Health advisory"
Nonregulatory levels of contaminants in drinking water that may be used as guidance in the absence of regulatory limits. They consist of estimates of concentrations that would result in no known or anticipated health effects (for carcinogens, a specified cancer risk) determined for a child or for an adult for various exposure periods.
An EPA document that provides guidance and information on contaminants that can affect human health and that may occur in drinking water, but which EPA does not currently regulate in drinking water.
Information on contaminants that can cause human health effects and are known, or anticipated, to occur in drinking water. Health Advisories are federal guidance values based on non-cancer health effects for different durations of exposure (e.g., one-day, ten-day, and lifetime).
