How Safe Is Swimming Pool Water?
Part 2 of 3
Suspended Matter: Pool Water Filtration
Swimming pool filters are the first step in pool water treatment. Good quality pool filters are designed to trap the most commonly occurring suspended matters in pools.
Pool water filters are commonly installed after pumps. Well maintained pools pay close attention to the quality and regular maintenance of pool filters.
Cryptosporidium, Giardia and Bacteria in Pool Water
Public pools in most states are required to maintain a residual level of chlorine to protect swimmers from common bacteria.
Is chlorine enough to protect a public pool from all bacteria and viruses? Well, Cryptosporidium, Giardia and other chlorine resistant micro-organisms have proven to resist chlorination. Internet search for “chlorine resistant microorganisms” or “Cryptosporidium and chlorine” can provide a lot of information on the subject.
The bottom line: No matter how chlorine provided, it does not provide adequate protection from Crypto, Giardia and a host of other microorganisms likely to be present in pool water.
This means, relying on chlorine alone for microbial protection is generally not a good idea for operators of public pools.
Chloramines, Chlorine smell and Eye & Skin Irritation
Chloramines are complex chemical compounds often found in pool water. When chlorine in pool water reacts with amine groups from some contaminants in pool water, they form chloramines. Chloramines are responsible for the “chlorine smell”. Worse, many scientific studies have linked chloramines to health risks including breathing difficulties, eye irritation, skin irritation and other more serious health conditions. Many technical papers are available on the health risks of chloramines.
