What are we measuring?
This measure tracks the number of health-based water violations by all medium to very large public water systems in Fulton County.  Health-based violations occur when a water system detects levels of a contaminant exceeding the safety level (called the maximum contaminant level (MCL)) or when the water system fails to treat the water as required to remove particular contaminants (called a treatment technique violation). Fulton County and the City of Atlanta operate the largest public water systems in the county, but there a number of smaller system included in this measure.

Why are we measuring it?
Health-based violations indicate conditions that may be hazardous to humans.  Excessive violations suggest systemic problems in the water distribution system.  Monitoring the number of violations helps assure residents that their drinking water is safe when violations are rare and alerts them to possible problems when violation become frequent.
How are we doing?
In 2018, there were two health-based violations reported to the EPA by medium to very large public water systems in Fulton County.  Since 2000, there have no more than four violations within a single year, with 2017 being the highest.
