The water
in public swimming pools contains microorganisms and unwanted substances, which
derive from the bodies of swimmers. Swimmers cause many pollutants to enter the
water, such as bacteria from saliva, pollution from swimwear, skin tissue,
sweat, nose and throat saliva, hairs, cosmetics and ammonia. Vouching for clean
swimming pool water through constant refreshment is often too expensive.
Furthermore, this does not solve the problem of pollutants that remain on
swimming pool walls. The water is recycled causing pollutant and pathogen
concentrations to increase. Microorganisms will multiply and this causes the risks
of contagion to increase.
Pathogenic microorganisms that can be found in swimming pool water are bacteria, viruses and parasitic protozoa. Young children, elderly people and people with damaged immune systems are more susceptive to infections caused by these species and will fall ill more easily. People that have an untreated form of cancer may also suffer from lower resistance to waterborne diseases. Not every person that is infected will fall ill but when or she can still cause contagion of other people.
