The economic evaluation of the costs and environmental benefits has been one of the main themes for the analysis of environmental projects. In the last decades several methods were developed to assess the environmental benefits and costs. Among these methods, the Contingent Valuation method has been one of the most used for economic evaluation of the environment. This article presents the use of Contingent Valuation method in the evaluation of the Second Stage of the Project Despoluição do Rio Tietê. It shows the state of the art of referendum contingent valuations models concerning estimation of willingness to pay parameters. One verifies that the application of models theoretically consistent, like Bounded Logit, results in smaller dispersion of parameters than the methods usually used linear and logarithmic LOGIT that imply the use of arbitrary measures to solve the resulting inconsistencies.
