CARRASQUERO FERRER, Sedolfo Jose et al. Physicochemical and microbiological quality of swimming pool water of two recreational complexes in Zulia State. Bol Mal Salud Amb [online]. 2016, vol.56, n.2, pp.202-210. ISSN 1690-4648.

The present study had as objective to analyze the quality physical-chemical and microbiological of the water of swimming pools of two recreational complexes located in west of the city of Maracaibo, Zulia state, in accordance with the established in the sanitary Venezuelan procedure, the official gazettes 4044, and 36395. Sampling was conducted in twenty (20) aimed at recreational pools located on two recreational complex. The parameters were measured to analyze the quality of water in swimming pools were true color, electrical conductivity, total solids, total dissolved solids, turbidity, total alkalinity, residual free chlorine, total hardness, pH, total coliforms, fecal coliforms and heterotrophic organismes. The physicochemical parameters: dissolved solids, turbidity and electrical conductivity presented average concentrations less than those established by the sanitary standards; however, the mean values of residual chlorine and pH were found outside the recommended ranges. The microbiological tests showed that 30% of the pools tested had an average value of heterotrophic organisms of 107 CFU / mL, higher than the limit set by Venezuelan law. 75 and 60% of the pools presented at least one positive test tube for total and fecal coliforms, respectively
