It might be disgusting, but there are times when diarrhea can be found in swimming pools.The CDC has released a booklet with recommendations for pool staff to do when they find fecal matter in the pool. Of course, the same goes for private pools.
When fecal matter is found in a pool, it needs to be closed immediately to allow the pool to be disinfected and prevent the spread of RWIs (recreational water illnesses).
If diarrhea is found in the pool:
- Close the pool
- Remove the fecal material and dispose of it, then disinfect what was used to remove it
- If necessary, consult an aquatics professional for more options
- Raise the free chlorine concentration to 20 ppm; maintain pH at 7.5 or less; and at 77°F; maintain the pool at those levels at least 12.75 hours
- Make sure the filtration system is operating the entire time
- Backwash the filter once disinfection levels are reached
- Allow swimmers back into the pool after the CT inactivation levels have been reached and the chlorine and pH have been returned to normal levels
