Finding a dead bird in your swimming pool is an unpleasant event that immediately raises concerns about water safety. While this situation requires swift and proper action, modern pool sanitation systems are highly effective at neutralizing most biological threats. The combination of chemical treatment and physical removal ensures the pool can be safely restored to a clean state with minimal disruption.
Assessing the Immediate Health Risk
The primary concern is the introduction of pathogens, such as bacteria, viruses, or parasites, which can be present in the bird’s feces or body fluids. Common bacterial contaminants like Salmonella and E. coli are potential risks from avian waste. These germs can cause gastrointestinal illness if the contaminated water is swallowed.
The risk level is directly tied to the pool’s water chemistry and the amount of time the bird was present. In a pool with adequate free chlorine levels, most germs introduced by a small animal are killed quickly, often within minutes. If the bird was in the water for a long time or if the chlorine concentration was low, the potential for contamination is significantly higher.
Safe Removal and Initial Handling
Before any physical contact, close the pool to all swimmers to prevent accidental exposure to contaminants. Wear personal protective equipment, specifically disposable gloves and eye protection, to create a barrier against pathogens. Use a deep net or a small bucket to scoop the dead bird from the water, taking care not to agitate the water nearby.
Once removed, immediately place the bird into a plastic garbage bag and then seal that bag inside a second one, a process known as double-bagging. Dispose of the sealed bag according to local waste disposal guidelines for biological matter. Afterward, clean the net or container used for removal by submerging it in the pool during the disinfection process. Finally, remove and discard the gloves and wash your hands thoroughly with soap and water for at least 20 seconds.
Restoring Water Safety
The next step involves chemical disinfection to eliminate any remaining microorganisms. Begin by testing and adjusting the pool’s pH level, aiming for a range between 7.2 and 7.5, which ensures the chlorine is most effective. To definitively kill any introduced pathogens, the water must undergo superchlorination, also known as shocking the pool.
Superchlorination Levels
While the Centers for Disease Control and Prevention recommends maintaining a free chlorine level of 2 parts per million (ppm) for 30 minutes for a small animal incident, many pool experts suggest a much higher concentration. A target free chlorine concentration of 10 to 20 ppm is a more robust approach to completely sanitize the water. This high chlorine level requires a specific contact time to be effective against all potential contaminants.
Circulation and Reopening
Once the shock level is achieved, the water must circulate through the filtration system for at least one full cycle, typically six to eight hours. The high concentration must be maintained throughout this process, and no one should enter the pool during this disinfection phase. After the contact time has passed, test the water again to ensure the chlorine levels have returned to a safe swimming range, which is typically between 1 and 4 ppm. Only when both the free chlorine and pH levels are within safe parameters should the pool be reopened for use.
