The Centers for Disease Control and Prevention (CDC) tracked reports of waterborne disease outbreaks that were linked to drinking water across the United States. This surveillance covered the years 2015 through 2020 and looked at the entire U.S. population.
The specific results of this tracking—like how many outbreaks happened, where they occurred, what germs caused them, or how many people got sick—are not detailed in the available information. This means we cannot say from this summary whether outbreaks increased or decreased during this time.
This type of report is important for public health officials to monitor potential problems with drinking water safety. For the general public, it serves as a reminder that water systems are monitored for safety, but it does not provide new information about current risks. Readers should know that their local water utility regularly tests water quality and provides annual reports on safety.
