Indicator Report - Community Water Systems with no MCL Violations

Why Is This Important?

"A community water system is a type of public water system that provides water to the same population year-round. Approximately three out of four North Carolinians reside in areas serviced by community water systems. Reducing contaminants protects the public's health by ensuring that those on CWS receive safe drinking water." - North Carolina Institute of Medicine. Healthy North Carolina 2020: A Better State of Health.

Data Notes

The HNC 2020 target, which is the target to be reached by 2020, is repeated in the data table for graphing purposes.

Definition

Community water systems are defined as a public water system that supplies water to the same population year-round. Under the Safe Drinking Water Act (SDWA), the Environmental Protection Agency (EPA) sets national limits on contaminant levels in drinking water to ensure that the water is safe for human consumption. These limits are known as Maximum Contaminant Levels (MCLs).

How We Calculated the Rates

Numerator: Number of citizens served by community water systems (CWS) that had no Maximum Contaminant Level (MCL) violations
Denominator: Total number of citizens served by community water systems (CWS)
