According to Cimi report on violence against indigenous people [1], the indigenous peoples denounce the Biopalma da Amazônia company, a subsidiary of Vale, for the impact of the contamination of water courses by pesticides.  The company is accused of disregarding the distance from the water course (known as "igarapé" in the Amazon) that cuts through the indigenous land and of diverting too much water toward their crops. According to the community, the oil palm plantations are drying up the sources of rivers. As a consequences,  the local population are getting ill.  Since 2012, the indigenous Tembé from the North of Pará have been trying to get compensation and mitigation actions for these impacts [2]. They also mentioned that it is mainly men who find work with the companies, but working conditions are often akin to “slavery”.

In 2014 the Evandro Chagas Institute confirmed water contamination with for example, endosulfan, a highly dangerous product for human health and already banned in several countries [4].  In 2016 the Biopalma company asked the the Federal Justice to ban indigenous demostration in the region of oil palm expansion.  However the  Public Ministry - MPF-, requested to the Federal Justice the cancelation of the Biopalma legal process against indigenous people, and the company to participate in a hearing with the També [5].

There is a palm oil extraction plant belonging to Biopalma to produce biodiesel in the municipality of Moju, 150 km from Belém, at a cost of 500 million USD for building it [7].
