The United States EPA and the Centers for Disease Control and Prevention (CDC) issued the following information on drinking water supplies and COVID-19:
FROM THE EPA
EPA has established regulations with treatment requirements for public water systems that prevent waterborne pathogens such as viruses from contaminating drinking water. These treatment requirements include filtration and disinfectants such as chlorine that remove or kill pathogens before they reach the tap. Additionally, WHO (World Health Organization)notes that, “conventional, centralized water treatment methods which utilize filtration and disinfection should inactivate COVID-19 virus.” https://www.epa.gov/coronavirus/coronavirus-and-drinking-water-and-wastewater
FROM THE CDC
The COVID-19 virus has not been detected in drinking water. Conventional water treatment methods that use filtration and disinfection, such as those in most municipal drinking water systems, should remove or inactivate the virus that causes COVID-19. https://www.cdc.gov/coronavirus/2019-ncov/php/water.html
FROM THE MWC
Markleeville Water Company uses filtration and disinfection to treat surface water. The water in the system is then tested to ensure the water has the proper amount of residual disinfection in our pipe system. Markleeville Water Company reports this information to the State and the County, and we are in compliance with their water quality regulations.
