residual chlorine, pool water, Timis County, case-study


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.
