With guidance from the CAO, in January 2002 the Mesa selected Stratus Consulting, Inc. (Stratus), to undertake an independent and participatory study of water quality and quantity in the mine’s area of influence. The main objective of the water study was to create new, trusted knowledge about the state of water sources in the region and the Yanacocha mine’s impacts on them, thereby ultimately contributing to the process of conflict resolution between the community and Yanacocha.

During the execution of the water study, the CAO, Stratus, and Mesa participants faced considerable challenges that spanned a wide range of themes from the technical to the social and political. In confronting these challenges, they experienced both successes and disappointments, and these generated a series of important lessons for Mesa members, the CAO, and outside observers. This monograph relates these experiences and these lessons.
