As temperatures rise across the island, public swimming pools fill with swimmers- but just how clean is the water?
While swimming is one of the oldest and healthiest human activities, pools can harbour hidden threats if not properly maintained. From parasites to bacteria, public swimming pools may carry pathogens that pose health risks to both casual swimmers and staff.
One of the most resilient dangers is Cryptosporidium, a chlorine-resistant parasite that can cause severe stomach upset. Other culprits include staphylococcus, fungi, noroviruses, and Legionella bacteria, which can trigger infections ranging from earaches to serious respiratory conditions.
Experts stress that chlorination alone isn’t enough. Pool safety depends on correct pH levels, water circulation, and hygiene practices- especially during peak summer use. Contrary to popular belief, that “chlorine smell” actually comes from chloramines, compounds formed when chlorine reacts with sweat or urine. These can irritate eyes, skin, and even trigger asthma in workers.
To minimise risk:
- Always shower before entering the pool
- Avoid swallowing pool water
- Report any “accidents” immediately
- Ensure regular cleaning and water replacement
Despite these concerns, experts agree that swimming remains a highly beneficial form of exercise- as long as public swimming pools are kept to strict hygiene standards.
