Abstract(s)
The poor water quality of recreational and rehabilitation pools,has been correlated to insufficient disinfection or human contamination, and can be a vehicle for transmitting diseasesto users. Because people with different characteristics attendpublic swimming pools with different purposes, the pool water quality control is essential to minimize hazards related tounsafe water.MethodsThis study was based on data collection of 144 samples between 2018 and 2020 in therapeutic and recreational pools(indoor and outdoor) in the Braganca district. The proportionof the number of bathers were estimated, as well as the microbial parameters: Total coliforms,Escherichia coli, enterococci, Pseudomonas aeruginosa, total Staphylococcus,Staphylococcus coagulase-positive and mesophilic microbial count. Results: The E. coli, enterococci and mesophilic microbial count werenot found in any sample. Unsafe pool water was mainly contaminated by both photogenicP. aeruginosa(6.3%) and total Sthaphylococcus (10.4%). Levels ofP. aeruginosaintherapeutic pools was greater than in recreational pools (indoor and outdoor) (10.5% vs 6.8% and 4.5%, respectively),while total Sthaphylococcus was absent in therapeutic pools and represent 13.6% and 10.6% of positivity in indoor and outdoors wimming pools, respectively. The bathers number medium of therapeutic, indoor and outdoor pools was 4.8, 3.4 and 6.9,respectively.
Conclusions: Overall, the results endorse the good water quality of theseswimming pools, mainly by the absent of faecally-derivedbacteria. The presence of P. aeruginosain therapeutic pools canbe explained by the type of users, while the high number of bathers may promote the growth of some microorganisms,particularly in outdoor pools
