DIAZ-SOLANO, Beatriz Helena; ESTELLER, María Vicenta  and  GARRIDO HOYOS, Sofía Esperanza. Physicist-chemistry and Microbiological Water Quality in Aquatic Parks. Hidrobiológica [online]. 2011, vol.21, n.1, pp.49-62. ISSN 0188-8897.

The purpose of this investigation was to analyze the water quality evolution in a water park, determining deterioration levels and probable causes, in this study were analyzed different parameters determining the presence of microorganisms, to propose water quality control systems for these establishments. As study zone was chosen the Morelos State, Mexico, which has four water parks. The study analyzed one of these parks, dividing the study as follow: Phase 1) Sampling of water in and out of the park, analyzing physicochemical and microbiological parameters; and Phase 2) Operational evaluation in six pools of water Park, assessing the electrical conductivity, Total Dissolved Solids (TDS), pH, color, turbidity and residual chlorine. The results were compared with Mexican Official Standards, determining whether there is deterioration in the quality of the resource in the operational processes of the parks. The Phase 1 gave as results raised levels in fats and oils (19.0 mg/L), color (100 UPt-Co), fecal coliforms (1.15 · 10⁴ NMP/100 mL) and total coliforms (1.70 · 10⁵ NMP/100 mL). The Phase 2 showed high values of pH (7.9-8.4), diminishing the efficiency in disinfection and a behavior differentiated in conductivity and TDS in swimming pools filtering systems. Since conclusions there decided that the water quality in Water Parks must be controlled in parallel to the operability in swimming pools, the processes of chloration must be standardized. The users are responsible for the deterioration of water and require the generation of an Environmental Management System.
