The CDC recommends maintaining a free chlorine concentration of at least 1 part per million in swimming pools, and at least 3 ppm in hot tubs. Pools should also strive for a pH of 7.2 to 7.8 ...
When any of these pool chemicals are used, it is very important to keep the pH of the pool in the range 7.2 to 7.8 – according to the Langelier Saturation Index, or 7.8 to 8.2 – according to the Hamilton Index; higher pH drastically reduces the sanitizing power of the chlorine due to reduced oxidation-reduction potential (ORP), while lower ...
As far as health experts know, the novel coronavirus doesn’t spread through water in pools, hot tubs, or water playgrounds, according to the Centers for Disease Control and Prevention.
S. aureus has a strong resistance to chlorine, which is one of the methods by which pools are often cleaned. [4] Other bacteria often found in recreational waters are Enterococci, [5] which is a genus of bacteria found in feces. Fecal contamination is one of the primary public health concerns in swimming pools. [4]
As an alternative to shock chlorination, some swimming pools are chlorinated by use of a chlorine-generating filter that electrolyzes common salt. Pools chlorinated by this method generally have lower levels of chlorine than directly chlorinated pools. Such pools are called saltwater pools. [citation needed]

While chlorine kills most bacteria such as E. Coli in less than a minute, it takes at least 16 minutes to kill Hepatitis A, and the Cryptosporidium parasite can last in the swimming pool for over ...
Indoor Swimming Pool. Respiratory risks of indoor swimming pools can include coughing, wheezing, aggravated asthma, [1] and airway hyper-responsiveness (spasms of the bronchial tubes in the lungs causing coughing and chest tightness). The chemicals used for pool water disinfection can react with organic compounds in the water to create ...
