PFAS hazard index
A dimensionless sum of source-defined PFAS concentration-to-health-based-water-concentration ratios; zero indicates no contribution, higher values indicate greater combined exposure, and 1 is the U.S. EPA action threshold under the applicable methodology, whose analytes, units, sample date, and version must accompany the value.
