The following information is taken from the CDC website.
Please visit the CDC website for complete information regarding COVID-19 and water.
There is no evidence that COVID-19 can spread to people through the water used in pools, hot tubs, or water playgrounds. Proper operation and disinfection of pools, hot tubs, and water playgrounds should kill the virus that causes COVID-19. Limit close contact with people outside your home in public spaces, both in and out of the water. Get more information about COVID-19 and water.
Kill Germs in Your Pool
Disinfection (with chlorine or bromine) and pH are the first defense against germs that cause recreational water illnesses. At the recommended levels, chlorine or bromine can kill most germs in the water within minutes.
As a backyard pool owner, you should check the disinfectant (chlorine or bromine) level and pH at least twice per day (and more often when the pool is in heavy use) to make sure they are correct:
- 1–10 parts per million (ppm) free chlorine or 3–8 ppm bromine
- pH 7.2–7.8
If the pH is too high or too low, it can cause problems, including decreasing chlorine’s or bromine’s ability to kill germs. It can also cause skin and eye irritation in swimmers and damage pool pipes and other equipment.
Considerations for Public Pools, Hot Tubs, and Water Playgrounds During COVID-19
As public aquatic venues open in some areas, CDC offers the following considerations for the safety of those who operate, manage, and use public pools, hot tubs, and water playgrounds. Public aquatic venues can be operated and managed by:
- city or county governments
- apartment complexes
- membership clubs (for example, gyms)
- schools
- water parks
- homeowners’ associations
All decisions about implementing these considerations should be made locally, in collaboration with local health officials. Operators of public aquatic venues can consult with local officials to determine if and how to implement these considerations while adjusting them to meet the unique needs and circumstances of the local jurisdiction. Their implementation should also be informed by what is feasible, practical, and acceptable.
