Managing faecal contamination in pools is not easy, requiring a balance between public health and operational considerations. Pool operators face difficult tasks when responding to faecal incidents, including identifying and confirming the presence of faecal matter and determining measures to mitigate the risk of infection.
Public health officials develop guidelines to ensure public safety and prevent unnecessary pool closures, considering harmful microorganisms in faecal matter, such as Cryptosporidium, a significant cause of gastroenteritis.
Determining the appropriate response to a faecal incident when there is doubt about the accuracy of the report is a key challenge. Confirming the presence of faecal matter is not always a straightforward process. After confirmation, pool operators must assess the risk of contamination and decide whether to allow bathing.
Solid faecal matter poses a lower risk of contamination than non-solid matter, which is more likely to disperse into the water. Other factors, such as pH and disinfection levels, type of disinfectant, and number of swimmers, also affect the risk of infection.
To manage these challenges, pool operators must maintain records of faecal incidents and protocols for responding to them. These protocols may include temporarily closing the pool, increasing water testing and disinfection, and providing swimmers with information on infection risks and how to protect themselves. These measures help ensure safe and healthy swimming while minimising the risk of faecal contamination.
