This study aimed to evaluate the environmental quality of the Apipucos dam in Recife-PE, through diagnosis of water quality using physical, chemical and microbiological parameters, as a function of the use and occupation of the soil. In this way, was made the water quality monitoring in three campaigns during the period between January 2007 and January 2008. In the first campaign were evaluated physical, chemical and microbiological parameters in bimensal periods on a schedule in three sampling points. During the second campaign the physical-chemical parameters were evaluated in the local, with weekly intervals in four sampling points. In the third campaign the physical-chemical evaluation was made at two depths related to water surface (30 and 60 cm), using 45 sampling points in order to identify areas with greater or lesser degree of impact. A bathymetric study was conducted to check the occurrence of silting in the dam. The observed results indicate that water quality shows high concentrations of organic pollution, with most critical points locatedin cell 2 of the dam. In respect to the presence of toxic substances tested, in general, the concentrations of metals were within the limits of CONAMA Resolution 375/05, except to the iron, copper and aluminum. For those impacts to the water quality of the Apipucos dam, can be considered the human activities, which have increased the process of environmental degradation of this resource. The bathymetric studies indicated that in the Apipucos dam not occurred significant silting or it was not remarkable. The lack of treatment of the domestic sewage and illegal use of land near the banks of the body of water are aggravating factors of their current conditions.
