The water bodies have the characteristics affected by diffuse pollution through the drift of pollutants in the runoff from rain events or also by occasional evictions. This research was conducted in pools of the Water Park in Pinhais/PR and aimed to assess the quality of waters and sediments of water bodies and their correlation with diffuse pollution. The analyses from some physico-chemical, bacteriological and organic compounds PAHs and n-alkanes in 6 points, indicated possible changes in the quality of these water bodies. These pools will be designed for future use of secondary contact recreation such as fishing and water sports in the LAW 189/87 - Pinhais-PR, indicating that the water pools must answer these CONAMA Resolution 357/05, which sets limits for physical- chemical, biological and metal species that may cause damage to health and the environment. To support the discussion of the results for PAHs in sediment and metal species, is used the CONAMA Resolution 344/04. The limits given by CONAMA resolutions 357/05 and 344/04, are safety values. Based on these results, we identified the influence of rainfall in the concentrations of all variables. By comparing the results with CONAMA Resolution 357/05 for freshwater class 2, it might be noted that the parameters salinity, dissolved oxygen, turbidity, ammonia, nitrite, nitrate comply with the limits imposed by resolution, for the DBO Most points analyzed was within the limits, but in one of the exceeded limit. For Fecal coliform, most points are presented within the limits established by resolution. The variable sulfide does not meet CONAMA 357/05. Of the seven metals analyzed in water cadmium and iron are found above the ceiling for CONAMA 357/05. The metals copper, zinc, cadmium, nickel and lead in sediments are within the limit of CONAMA Resolution 344/04, but in some sampling sites indicated PAH contamination source elements petrogenic when confronted with the limits specified in this same resolution. To avoid the exceeding the limits, since some of the points are very close, or extrapolating the limits, it is necessary prevent the entry of polluting the pools of the park in question, due to the high risk of losing the quality of these bodies water and impair its function for society. The research identified that the increase in pollution load is powered by the runoff of rainfall, implying thus the need for control of diffuse pollution to the park area. One of the possible solutions would be the deployment of constructed wetlands, which can act as barriers to the entry of pollutants, mainly pools nearest paved road structures.
