The beef chain in Brazil occupies a prominent position in the context of rural Brazilian economy, occupying large areas of national territory and accounting for the generation of jobs and rent of millions of Brazilians. But with the growth of this activity was accompanied by possible negative environmental impacts that opposes the dynamic balance of sustainability. Thus it was necessary to characterize these negative environmental impacts related to water resources in the stages of the production chain of beef: Cattle and slaughterhouses/ refrigerators.In the research were emphasized water consumption and generation of bovine tailings causing potential pollution of water resources defined in geographical areas of the mesoregions in the state of Pará. The methodology was used for qualitative and quantitative bibliographic data and statistics research, with the collaboration of the federal and state institutions and the data analysis was presented through graphs and tables and the estimation of some indicators of pollution. The results confirm the great pollution to water resources generated receptors tailings cattle with large increase of BOD (Biochemical Oxygen Demand) both in Cattle and slaughterhouses/ refrigerators activity, where it generated a large amount of organic matter. It was concluded the importance of using sustainable production measures such as reusing byproducts of cattles laughterhouse and the use of strategies Cleaner Production.
