Abstract
OBJECTIVE: The aim of the study conducted was to investigate residual chlorine concentrations in pool water from Timis County, Romania over two years (2016-2017).
 MATERIAL OF STUDY consisted of a sample of 50 pools from Timis County from which were collected and analyzed 154 water tests.
 THE METHOD was an observational inquiry (case-study) of the residual chlorine concentrations considering spatial and temporal distribution and comparing with actual standards (4 groups of residual chlorine concentrations were considered).
 RESULTS: Average concentrations of residual chlorine exceeded 0,5mg/l in 30 investigated pools. Monthly mean concentrations of residual chlorine exceeded 0.5mg/l 20 of the 24 months of the investigation period. The maximum value of residual chlorine monthly mean concentration was recorded in July, 2017 and the highest average concentration at the pool I3. An Anova Oneway analysis indicated a statistically significant difference (F=30.312, Sig.0.000) between the 4 groups of residual chlorine concentrations: over 1.5 mg/l / (0-0.5mg/l, Sig.000; 0.5-1mg/l, Sig.0.001, 1-1.5mg/l, Sig.0.009).
 CONCLUSION: There is an over-chlorination of pool water of Timis County, Romania, with spatial and temporal variation and statistically significant differences between groups of residual chlorine concentrations.
Highlights
Pool water chlorination is an important preventive measure against infectious diseases transmitted through water to and between swimmers (Elmir et al, 2007)
Temporal distribution Monthly mean concentrations of the residual chlorine measured in pool water of Timis County were very high (0.5-3.25mg/l) exceeding maximum admitted concentration (0.5mg/l) (WHO, 2008a) in 20 of the 24 months of the study
There is a statistically significant difference between the average concentration group and the other groups (0-0.5mg/l, 0.5-1mg/l and 1-1.5mg/l) and a high variation of the recorded values over 1.5 mg/l. All these results suggest an overchlorination of pool water in Timis County and an imbalanced position between two risks: infectious diseases when it is insufficiently chlorinated and the health effects of chlorination by products when it is over chlorinated
Summary
Pool water chlorination is an important preventive measure against infectious diseases transmitted through water to and between swimmers (Elmir et al, 2007). Additives (cyanuric acid and its compounds) are used in order to stabilize residual chlorine (Wahman, 2018) and keep its disinfectant action. Exposure of swimmers in indoor swimming pools to disinfection byproducts (Kogevinas et al, 2010) and to chlorinated water (Nickmilder & Bernard, 2007) produced severe health effects such as allergies (asthma) and genotoxicity. An analysis of good practices regarding pool water disinfection with chlorine needs to be performed in the area at the community level in order to see if the actual regulations are implemented
