The Role of Hygiene in a Sustainable Approach to Managing Pool Water Quality

To achieve sustainable swimming pool water management, it is necessary to minimize the consumption of energy, water, and chemical agents to maintain the appropriate water quality. Some of the pollutants are introduced by swimmers and can be relatively easily removed if swimmers take a shower before entering a pool. Thus, this research questions how much of an impact this simple act could have on the water quality and generally on sustainable water management in swimming pools. To address this question, experiments were conducted at the AGH Swimming Pool in Kraków, in a real facility—a hot tub—with the participation of volunteers who took a shower in Variant 1 and did not in Variant 2. The assessment was made on the basis of selected microbiological and physicochemical parameters of swimming pool water, including disinfection by-products. The research results proved that taking a shower can significantly reduce the load of pollutants users introduce into swimming pool water and can contribute to more efficient and ecological treatment of swimming pool water and minimize the negative impact on the health of swimming pool users (microbiological contaminants and precursors of harmful chlorination by-products).
