Neuquén Province's Official Defender of Minors filed an amparo action to protect the health of children and youth in the indigenous Mapuche community of Paynemil, because they had been exposed to water contaminated with lead and mercury. The applicant requested that the State be ordered to provide enough drinking water to ensure the survival of the affected community, to conduct the diagnosis and treatment of affected minors, and to adopt adequate measures to prevent future soil and water contamination.
