Trihalomethanes (THM) are by-products of dis-infection of bathing waters with chlorine. They are formed by reaction of chlorine and/or bromine with the organic matter present in the water. THM represent a major problem in public swimming pools in Slovenia as according to the data of National monitoring program THM levels in public swimming pools in Slovenia in years 20052011 exceeded the legally permitted limits in 15 % to 80 % of samples. In the countries where level of THM in the bathing waters is not regulated by national legislation, the situation could be much worse. The THM concentrations in Slovenian swimming pools are not high; although each exceeded THM value is harmful to human health. When an adequate quantity of water in public swimming pools is exchanged on regular basis, the levels of THM are usually not exceeded but when the quantity of exchanged water is not adequate or technology of bathing water preparation is not appropriate, THM values usually exceed legally permitted limits. Todays state of the art of bathing water preparation techniques allows the efficient preparation of bathing water without resulting in increased levels of THM.
