Aquatic facilities such as swimming pools, water parks, hot tubs, lakes, rivers, and the ocean can carry bacteria and make you sick.

Tips for homeowners with pools or hot tubs

We do not inspect private pools, but we’re happy to help provide guidance.

• 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 level and pH at least twice per day to make sure they are correct. The levels are:
  • 1–4 parts per million (ppm) free chlorine or 3–8 ppm bromine
  • pH 7.0–7.8
• Inaccurate pH and disinfectant levels can lead to bacteria growth and damage pool pipes and other equipment.
• Find more information on how to ensure your backyard pool/spa is safe.

Reach out to your medical provider if you suspect you may have developed an illness after recreational water use.
