Sukrut - Purify with confidence Overview of Pool Water Looks can be deceiving. Shimmering blue water in a swimming pool looks very inviting. Yet, the pure looking water can harbour plenty of bacteria, viruses, protozoa, algae, cysts and other microorganisms that can pose grave danger to health. How can crystal clear swimming pool water harbour bacteria and viruses? The most obvious source is swimmers enjoying the swimming pool! If you think about it when a person enters a pool the pool starts getting contaminated with their body fluids like sweat, saliva, skin particles, hair, faecal coliforms, uric acid, traces of any microbial contaminants on the swimmers’ bodies, etc. Even a person with perfect personal hygiene can potentially introduce a multitude of microbes into swimming pool water. Moreover, a diverse variety of organic contaminants also enters pool water with swimmers and provides nutrition to the microbes in pool water. In addition to this, pools receive their share of bird droppings. Tree leaves and bark, dust and other environmental contaminants which all add to the microbial load in pool water along with food for the microbes already in food water. All the microorganisms that enter a pool remain there, happily feeding on the various organics and continue to grow to turn the pool into a broth brimming with bacteria, viruses, protozoa, cysts, algae and more. Considerations Doesn’t chlorine protect pool water? Yes and no. Swimming pools are required to have a residual chlorine level to protect swimmers from infecting one another. However, Chlorine brings 2 challenges to swimming pools. Chlorine Resistant Microorganisms While Chlorine certainly provides protection from some microorganisms, it is perfectly useless against Cryptosporidium and Giardia. In fact, Chlorine is so ineffective against such microorganisms, that they are called Chlorine Resistant Microorganisms. Chloramines Chlorine reacts with various organic and urea compounds that enter the pool from swimmers’ body fluids, traces of after shaves, perfumes, makeup and other contaminants. Chlorine reacts with these contaminants to form Chloramines. Chloramines are proven to be carcinogenic and are linked with breathing difficulties and various types of cancer.
