Safety, maintenance, and operation of public pools, spas, and water attractions

Pool & Spa Disinfection

Disinfection means removing bacteria, parasites and viruses from the water by sanitizing the pool water.  Chlorine is the most common disinfectant used in swimming pools and spas.

Fecal, Vomit, or Blood Incidents

  • You must disinfect when there is a fecal, vomit, or blood accident in the pool water.
  • Close the pool and follow CDC Fecal Incident Guidelines. For blood or vomit, follow the same steps as for formed stool incidents.
  • Document the incident on the DATCP Fecal, Vomit or Blood Incident response form. Incident forms must be kept for at least 2 years.

Pool Deck or Surface Disinfection

  • When blood, vomit, or feces ends up on a pool surface or deck, the area must be cleaned and disinfected immediately to prevent the spread of illness.
  • Block off the area and follow the CDC Body Fluid Spills on Pool Surfaces steps.

Pool & Spa Water Testing

  • Periodically, we may collect a water sample from a public pool for routine testing. Bacteria can grow in pool water when disinfectant levels are below the minimum requirements and/or the pool filtration system is not working properly. Unsatisfactory water test results are indicators that the pool is not being properly maintained.
  • A water test is unsatisfactory if coliform bacteria, E. coli bacteria, or Pseudomonas aeruginosa bacteria are present.

Unsatisfactory Water Test Disinfection Steps

  • If your facility’s pool or spa has had a pool water test come back positive for the presence of E. Coli or coliform bacteria, follow the steps listed in the CDC Diarrheal Incident Response Guidelines.          
  • If your facility’s pool or spa has had a pool water test come back positive for the presence of Pseudomonas aeruginosa, follow the steps listed in Disinfection of Pools and Spas for Pseudomonas aeruginosa.
  • The pool/spa may reopen once you have followed the disinfection steps and chemical levels are back in approved ranges.  For coliform present test results, no further notification is required to us. For E. Coli or Pseudomonas aeruginosa present test results, contact your assigned sanitarian or email us to say the pool water has been disinfected and the pool is reopened.  The sanitarian will coordinate a resample of the pool water.
