“…The results of P. aeruginosa monitoring in swimming pool water were very different in the different studies. For example, the percentage of positive samples for P. aeruginosa was 0% and 63.6% in Iran [43,44], 3.3% and 21.7% in Egypt [45,46], 19.1% in Italy [47], 38% in Northern Ireland [48] and 69.2% in China [49].…”

Considering the fact that water is a basic need of every living being, it is important to ensure its safety. In this work, the data on the presence of the opportunistic pathogen P. aeruginosa in drinking water (n = 4171) as well as in pool water (n = 5059) in Primorje-Gorski Kotar County in Croatia in the five-year period (2016–2020) were analysed. In addition, the national criteria were compared with those of neighboring countries and worldwide. The proportion of P. aeruginosa-positive samples was similar for drinking water (3.9%) and pool water (4.6%). The prevalence of this bacterium was most pronounced in the warmer season. P. aeruginosa-positive drinking water samples were mostly collected during building commissioning, while pool samples were from entertainment and spa/hydromassage pools. Outdoor pools showed a higher percentage of positive samples than indoor pools, as well as the pools filled with freshwater rather than seawater. The highest P. aeruginosa load was found in rehabilitation pools. Croatia, Serbia and Montenegro are countries that have included P. aeruginosa in their national regulations as an indicator of the safety of water for human consumption as well as for bottled water, while Slovenia and Bosnia and Herzegovina have limited this requirement to bottled water only. In the case of swimming pool water, this parameter is mandatory in all countries considered in this study.

“…Following ozone oxidation in pool water, the production of DBPs is expected to decrease as DOC chlorine reactivity diminishes. Well-established technology for the treatment of drinking water has become increasingly important, but its application in swimming pools is still very limited (Firuzi, 2020).…”

Swimming pools are common source of pollution especially public one. Recycled water should be chemically treated and microbial decontaminated. Water to be free of destructive substances, microscopic organisms, infections, green growth, pathogens, and reasonable for utilize by swimmers. This means that expansive particles are reduced to smaller volumes, which led to decay more efficiently through a channel. Since the natural matters produced a bacterial substitute, it will cause an increase in bacterial growth within the system. The regrowth of microscopic species in a conveyance framework is a negative effect. By injecting ozone into a sand channel, this will be converted into a positive effect. According to this research, ionization can improve channel performance. Ozone increases material biodegradability and microbial growth while also increasing oxygen concentration in the channel. When ozone is applied to natural carbon as total organic carbon (TOC) expulsion in a sand channel, it can be increased by up to 35%.

“…Besides, such water may irritate the mucous membranes of the eyes and the respiratory tract and pose a toxic hazard in emergencies (overdose). The chemical transformation of substances contained in the water is of particular relevance since it results in the formation of organic halogen compounds dangerous to human health (Carter and Joll, 2017;Firuzi et al, 2020;Liu et al, 2020;Wyczarska-Kokot et al, 2020;Zhang et al, 2022). In new regulatory documents, significant changes have affected chlorine and chlorination by-products.…”
