Drinking Water Information


Last year gave our community so many things to worry about. Water quality was not one of them.

Our top priority is making sure that the water you use to wash your hands, bathe yourself and your children, and prepare healthy meals meets all state and federal drinking water standards.

Our scientists and water quality professionals perform more than 195,000 tests per year on your drinking water to assure its safety. 2020 was another year with zero water quality violations.

Charlotte Water customers will start receiving their 2020 Drinking Water Quality Report in June 2021, which is an overview of our more detailed report. For the more detailed version, view the 2020 Consumer Confidence Report at www.CLTWaterWQReport.org.

​Charlotte Water's Consumer Confidence Report (CCR) – also known as a water quality report or a drinking water quality report – provides important information about the quality of the water we provide for our customers. The U.S. Environmental Protection Agency and the State of North Carolina require all drinking water providers to publish a CCR each year for the water quality of the previous year. So the CCR released in 2021 reflects data collected in 2020. 


The most important thing about a CCR is the transparency in water quality data the report provides customers, as well as notification of any water quality violations.


​A water quality violation occurs when any contaminate is found at levels higher than the EPA allows. The violation requires the water provider to notify customers immediately about what was found in the water and any health effects it might have. It also can require the provider to enhance or change its treatment or monitoring of the water.


A contaminant is anything found in your water that is not a water molecule, which is why we prefer to think of them as impurities. Contaminants/impurities can be good or harmful to your health, depending on the substance and quantity. For example, E. coli is a very small organism that is harmless at low levels but can make people sick in large enough quantities. On the other hand, chlorine, which is used in the water treatment process as a disinfectant against bacteria like E. coli, is also an impurity, but it is added at very safe levels to ensure high-quality drinking water.




​Yes, the presence of contaminants does not always create a water quality violation. There are levels of some contaminants considered to be safe. 


​Yes. A water provider can receive a violation for incorrect sampling techniques or failure to submit samples on time. 

​No. For another year, we are proud to report we delivered high-quality, clean drinking water with zero water quality violations. In a year that gave our community a lot to be concerned about with COVID-19, water quality was not one of them.

​We performed more than 195,000 tests this year for more than 150 regulated contaminants and more than 740 unregulated contaminants. None of these found contaminants or impurities that exceeded EPA regulations.
