Conteúdo:	The objective of this study was to evaluate the efficiency of Environmental Adjustment Contract for pig production (EAC) in improving the water quality in Pinhal River sub-basin, located in Concordia, west part of Santa Catarina State. The monitoring of water parameters occurred in eight sites of the river, during three years (2006-2009). To assess whether the EAC was efficient, Brazilian Water Law was used. The average annual concentrations of Total Dissolved Solids (TDS) were: 130.2 mg/L, 137.0 mg/L, and 99.8 mg/L. Turbidity showed the same trend of TDS. Concentrations of nitrate and Total Phosphorus (TP) decreased from 2006 to 2009; nitrate from 1.81 mg/L NO3-N to 1.54 mg NO3-N; TP from 0.29 mg/L to 0.10 mg/L, respectively. The same trends occurred for Fecal Coliforms and E. coli. These results show that obligations proposed by EAC had potentially improved water quality. These results can help the government, farmers, and society to establish environmentally sound and sustainable programs for pig production.
