By the whole Brazilian coast can be observed densification of urban occupation. Many times without proper precautions in respect of waste produced by human activities, especially in the case of domestic sewage. The lack of sanitation associated to the increased occupation represents a risk for the quality of water resources. This study was developed in the east coastal area of Ceara state with the objective of evaluate the impacts caused to the aquifer dunes by the lack of basic sanitation. Groundwater samples were analyzed to determine the concentrations of nitrate, nitrite, chloride and coliforms. In 7% of samples the concentrations of chloride and nitrate are above the potability standards and 93% was detected the presence of total or fecal coliforms, indicating impaired quality of water resources by human activities such as the adoption of poor sanitation systems.
