“…The present study did not aim at individually quantifying the TTHM produced such as: chloroform (CHCl 3 ), bromodichloromethane (CHClBr 2 ), dibromodichloromethane (CHBr 2 Cl), bromoform (CHBr 3 ) and other components such as haloacetic acids (HAA). Although, it is important to note that other similar studies indicated the higher presence of chloroform and haloacetic acids 15 as being the principal compounds contained in drinking water.…”

“…Several of these studies are still focused on the new testing (or already known) techniques for detecting and removing the TTHM and NOM from drinking water 15 . Though, in the last decade, a significant increase in papers regarding the study of these compounds and their association with the induction of some neoplasms can also be found.…”

“…In Brazil, this kind of monitoring has still been scarce 18,19 . In Brazil, the majority of the researchers working on TTHM and disinfection by products investigate the methods for detecting or removing these compounds from the drinking water 15,20 , are made under laboratory conditions.…”

The reduction of the incidence of water-borne diseases is achieved with the diffusion of the use of chlorination techniques. However, in spite of the benefits of this disinfection method, the reactions of chlorine with the natural organic matter occurring in the water induce the production of disinfection by products such as trihalomethanes. These products have already been associated with the incidence of some cancers types. Considering that in the Brazilian legislation, it is not mandatory measuring and controlling the occurrence of trihalomethanes at the exitand during the water distribution to the consumer. This study aimed at analyzing the relationship between chlorination and its by products. Thus, this project evaluated the concentrations of trihalomethanes in water collected at different points of supply in the municipality of Colombo, Paraná, Brazil, during the period from November 2015 to February 2016. Chromatographic methods were employed, besides the spreadsheets provided by the Health Surveillance of Colombo for comparison. The found values were tabulated and they were compared with the limits established by the Brazilian Ministry of Health- Ordinance No 05/2017. The results confirmed that the values of those provided by the concessionaire responsible for the city water treatment and supply, and being within the standards determined by the legislation.
