ENVIRONMENTAL MONITORING PLANNING IN RIVER BASINS: THE CASE OF PIG FARMING IN RIVER PIRANGA BASIN

Resumo

The integrated vision of the territory and understanding of how the anthropic activities influence the available natural resources is the key for guiding the inspection and environmental control actions which, when applied to river basins, directly influence the quality and/or quantity of water. In 2013 an environmental inspection project was elaborated for pig farming activity in River Piranga's Planning and Management of Water Resources Unit (Unidade de Planejamento e Gestão de Recursos Hídricos - UPGRH), in which it encompassed the following phases: orientation, field of activity and monitoring of post-fiscal actions. The objective of this article is to demonstrate the efficacy of the technical planning in river basins for the execution of environmental inspection. This is achieved by evaluating the water quality performance indicators before and after inspection, with the application of statistical tests. The continuous inspection increased the environmental regularization in the basin, since 94.11% of the fined enterprises were regularized. The implementation of a directed monitoring network of water quality enabled, on the part of the entrepreneur, the acknowledgment that pig farming contributes to the increase of the thermotolerant coliforms parameter and not only the gap in sewage treatment in the region.
