Suggested Pool Operation and Training Procedures

The following recommendations for training and operation are suggested:

1. Provide training for all persons responsible for the maintenance and operation of the swimming pool. Sources of training include state and local health department training and the National Swimming Pool Foundation Certified Pool Operator courses.
   
   
2. Maintain the recirculation and filtration equipment to provide maximum filtration. Many pools are periodically overused (e.g. winter weekend usage at many hotels and motels). These pools need filtration equipment that exceeds the state required minimums just to maintain normal water quality.
   
   
3. Maintain the chemical feed equipment and chemical levels at optimal levels. This includes disinfectant levels, and also includes maintaining optimal pH, total alkalinity, hardness and temperature. Lack of proper water balance can greatly effect disinfection times.
   
   
4. Follow the recommended disinfection procedures outlined below whenever a fecal accident occurs (especially an accident involving an unformed stool), and whenever it is suspected that the pool may be contaminated by Cryptosporidium.
   
   
5. Train staff (lifeguards, instructors, etc.) to report illnesses they experience to the management and not to swim if ill with diarrhea or abdominal cramps.
   
   
6. Develop a policy for pool usage by diaper-aged children. These children are the most likely to have a fecal accident.
   
   
7. Provide signs in a conspicuous location before pool entry. The sign might state: "If you have diarrhea, please do not use the pool.", "Shower before entering the pool.", "Report illnesses to the management." Then enforce the rules.
   
   
8. Use club or organization newsletters to remind patrons not to use the pool if ill.

Following these recommendations may not completely eliminate the risk of Cryptosporidium contamination of your pool, but should help reduce the risk.
