Disinfection by-products monitoring in water of selected outdoor swimming pools in Opole Voivodship

Abstract

The aim of this study was to determine the level of disinfection by-products in selected outdoor swimming pool in the Opole Voivodship. The authors paid special attention to the determination of the concentration of trihalomethanes (THMs), which are formed during disinfection in water. Five outdoor swimming pools were selected in five different cities located in Opole Region. The level of trihalomethane (THM) concentrations in the analyzed waters was found to be in the wide range from 15 to more than 550 µg/L. The dominant compound of THMs was chloroform because of chlorine application in the disinfection method.
