In March 2006, the Federation of Native Communities of the Corrientes River (FECONACO) asked EarthRights International (ERI) to undertake a mission to the Corrientes River basin in the northeastern Peruvian Amazon to investigate the social, environmental, and human rights impacts of more than 30 years of petroleum production activities. One year later in conjunction with the filing of a lawsuit against Occidental Petroleum, this report of ERI's findings was released. This report summarizes the impacts of Occidental's activities in the region as well as explains the legal grounds for civil demands due to Oxy's deliberate use of substandard technology.
