An analysis of the quality of the water was in a coastal area of Nuqui, considering the concentrations of dissolved oxygen (OD), pH, salinity, conductivity, turbidity, nutrients (phosphates, nitrites and nitrates), fecal coliform, total dissolved solids, DBO5, DQO, fats and oils. In situ and sampling at low and high tide, at stations located at the mouth of water sources receiving wastewater discharges in the area of interception with the coastal zone and directly on the coastal area measurements they were made. This in order to determine the effects of human disturbance on the physico-chemical quality of coastal waters and evaluate their status as a priority for the establishment of biological groups ecosystem. To do this, in situ measurements and analysis they were made in laboratory physicochemical variables and the results were compared with standards and water quality standards for the preservation of wildlife and aquatic flora. It was found that although the monitored parame ters did not show concentrations indicating a constraint for the development of aquatic organisms, there are specific areas according to the pressures of urban activities can affect their development for the contribution of higher po- llutant loads of fecal coliforms, DBO5, DQO, phosphates, nitrates, nitrites, fats and oils that are deposited on inland water sources that drain into the coastal zone.
