Protecting the health of La Oroya's residents from toxic pollution
For more than 20 years, residents of La Oroya have been seeking justice and reparations after a metallurgical complex caused heavy metal pollution in their community—in violation of their fundamental rights—and the government failed to take adequate measures to protect them.
On March 22, 2024, the Inter-American Court of Human Rights issued its judgment in the case. It found Peru responsible and ordered it to adopt comprehensive reparation measures. This decision is a historic opportunity to restore the rights of the victims, as well as an important precedent for the protection of the right to a healthy environment in Latin America and for adequate state oversight of corporate activities.
Background
La Oroya is a small city in Peru’s central mountain range, in the department of Junín, about 176 km from Lima. It has a population of around 30,000 inhabitants.
There, in 1922, the U.S. company Cerro de Pasco Cooper Corporation installed the La Oroya Metallurgical Complex to process ore concentrates with high levels of lead, copper, zinc, silver and gold, as well as other contaminants such as sulfur, cadmium and arsenic.
The complex was nationalized in 1974 and operated by the State until 1997, when it was acquired by the US Doe Run Company through its subsidiary Doe Run Peru. In 2009, due to the company's financial crisis, the complex's operations were suspended.
Decades of damage to public health
The Peruvian State - due to the lack of adequate control systems, constant supervision, imposition of sanctions and adoption of immediate actions - has allowed the metallurgical complex to generate very high levels of contamination for decades that have seriously affected the health of residents of La Oroya for generations.
Those living in La Oroya have a higher risk or propensity to develop cancer due to historical exposure to heavy metals. While the health effects of toxic contamination are not immediately noticeable, they may be irreversible or become evident over the long term, affecting the population at various levels. Moreover, the impacts have been differentiated —and even more severe— among children, women and the elderly.
Most of the affected people presented lead levels higher than those recommended by the World Health Organization and, in some cases, higher levels of arsenic and cadmium; in addition to stress, anxiety, skin disorders, gastric problems, chronic headaches and respiratory or cardiac problems, among others.
The search for justice
Over time, several actions were brought at the national and international levels to obtain oversight of the metallurgical complex and its impacts, as well as to obtain redress for the violation of the rights of affected people.
AIDA became involved with La Oroya in 1997 and, since then, we’ve employed various strategies to protect public health, the environment and the rights of its inhabitants.
In 2002, our publication La Oroya Cannot Wait helped to make La Oroya's situation visible internationally and demand remedial measures.
That same year, a group of residents of La Oroya filed an enforcement action against the Ministry of Health and the General Directorate of Environmental Health to protect their rights and those of the rest of the population.
In 2006, they obtained a partially favorable decision from the Constitutional Court that ordered protective measures. However, after more than 14 years, no measures were taken to implement the ruling and the highest court did not take action to enforce it.
Given the lack of effective responses at the national level, AIDA —together with an international coalition of organizations— took the case to the Inter-American Commission on Human Rights (IACHR) and in November 2005 requested measures to protect the right to life, personal integrity and health of the people affected. In 2006, we filed a complaint with the IACHR against the Peruvian State for the violation of the human rights of La Oroya residents.
In 2007, in response to the petition, the IACHR granted protection measures to 65 people from La Oroya and in 2016 extended them to another 15.
Current Situation
To date, the protection measures granted by the IACHR are still in effect. Although the State has issued some decisions to somewhat control the company and the levels of contamination in the area, these have not been effective in protecting the rights of the population or in urgently implementing the necessary actions in La Oroya.
Although the levels of lead and other heavy metals in the blood have decreased since the suspension of operations at the complex, this does not imply that the effects of the contamination have disappeared because the metals remain in other parts of the body and their impacts can appear over the years. The State has not carried out a comprehensive diagnosis and follow-up of the people who were highly exposed to heavy metals at La Oroya. There is also a lack of an epidemiological and blood study on children to show the current state of contamination of the population and its comparison with the studies carried out between 1999 and 2005.
The case before the Inter-American Court
As for the international complaint, in October 2021 —15 years after the process began— the IACHR adopted a decision on the merits of the case and submitted it to the Inter-American Court of Human Rights, after establishing the international responsibility of the Peruvian State in the violation of human rights of residents of La Oroya.
The Court heard the case at a public hearing in October 2022. More than a year later, on March 22, 2024, the international court issued its judgment. In its ruling, the first of its kind, it held Peru responsible for violating the rights of the residents of La Oroya and ordered the government to adopt comprehensive reparation measures, including environmental remediation, reduction and mitigation of polluting emissions, air quality monitoring, free and specialized medical care, compensation, and a resettlement plan for the affected people.

International Arbitration Tribunal rules in favour of a Canadian company and puts foreign investment above Colombia's legitimate right to protect Santurbán
Bucaramanga, Bogotá, Washington, Ottawa. National and international civil society organizations are widely rejecting the decision made by the International Centre for Settlement of Investment Disputes (ICSID) on September 10 in the case of Eco Oro v. Colombia, for at least three reasons: we consider that (i) it is inconsistent and reflects a profound ignorance of the socio-environmental complexity of the case; (ii) it is the result of an unfair and widely discretionary investment arbitration system that allows for arbitrary decisions made by those who oversee these cases and, (iii) increases the risk of further arbitrations being brought against the State of Colombia at the ICSID. ICSID is one of the institutions responsible for resolving disputes between States and international investors — in this case, within the context of the Canada-Colombia Free Trade Agreement. In the case of Eco Oro v. Colombia, the ICSID Tribunal concluded that, although the protection measures of the páramos adopted by Colombia were legitimate and did not constitute an expropriation of the rights of the Canadian company Eco Oro, its actions in the delimitation of the Páramo de Santurbán did violate the “minimum standard of treatment” to foreigners. The Tribunal has yet to decide on compensation for damages to Eco Oro and has asked both parties for more information to inform its decision. The Tribunal’s decision was the result of a process initiated by a supranational arbitration claim filed by the Canadian company Eco Oro against Colombia in 2016, which questioned the decisions made by the Colombian government to protect the páramos — the natural source of water for 70% of inhabitants. The Canadian investor [Eco Oro] intends to construct the Angostura gold mine in the Santurbán páramo, located in the northeast of the country. An inconsistent decision that ignores the socio-environmental complexities of the case. The majority of the Tribunal held that the decisions made by the Colombian government were in accordance with Colombian national law and were made with the legitimate aim of protecting the environment. In addition, the Tribunal recognized that the páramos are being threatened by both human intervention and climate change and that the possibility of their recovery from mining activities is very low, which is why it is necessary to protect them. As a result, the Tribunal rejected Eco Oro’s argument that the precautionary principle was not applicable, and pointed out that the Santurbán case was an example where it was, in fact, relevant. This was the grounds for rejecting one of Eco Oro’s claims that its rights had been indirectly expropriated by the State of Colombia. On the contrary, the Tribunal found that the measures adopted by the country were a legitimate exercise in environmental protection. However, when examining a second claim, the Tribunal explained that the inconsistency, hesitation and inaction of the State of Colombia in the delimitation of the Santurbán páramo had thwarted Eco Oro's investment expectations without any “apparent legitimate justification,” and had therefore not granted the investor "fair and equitable treatment" in accordance with the "minimum standard of treatment" for foreigners. This last ruling of the Tribunal is inconsistent. It ignores the socio-environmental complexity of the case and the challenges of materializing the right to environmental participation within the process of delimitation of the páramo. Although the decision recognizes that the delimitation involves managing widely disparate interests throughout the process, in the end — in a ruling far removed from the reality of Santurbán and its communities — the Tribunal took this process lightly, dismissing its complexities, and appears to have not taken it as legitimate and sufficient justification. An unpredictable, limiting and unfair arbitration system. "The Tribunal's decisions are not predictable, since decisions in one case do not bind future rulings on environmental issues. There is no precedent set, as traditionally understood in the system. The breadth of the clauses and the arbitrators' freedom of interpretation are excessive, which is problematic not only for Colombia but for all countries in the region," said Yeny Rodriguez, a lawyer with the Interamerican Association for Environmental Defense (AIDA). This decision allows mining investment to prevail over the Colombian State's obligation to protect the environment and the water of Colombians. We question the fact that the Tribunal has made its decision but has not judged the lack of due diligence by the Canadian company who knew from the beginning that its mining project overlapped with a páramo zone — a sensitive ecosystem protected by national law. This case demonstrates the arbitrary and overreaching nature of the supranational arbitration system, and the way in which it disciplines and punishes the governments of the Global South. It’s worth remembering that in February 2019, the Tribunal rejected the possible participation of the Santurbán Committee in the process. Uncertainty for Colombia. Carla García Zendejas, Director of the People, Land and Resources Program of the Center for International Environmental Law (CIEL) stated, "The legal uncertainty that the supranational investment arbitration system represents for Colombia is enormous. The high levels of arbitrariness that characterizes the system leads to penalizing States for any circumstance in which expected profits are affected. And this is especially critical for Colombia, as there are other lawsuits against the country resulting from extractive projects linked to Santurbán and other fragile ecosystems. This could mean a domino effect of lawsuits and heavy penalties against Colombians." Two other lawsuits are currently underway before ICSID against the country by Canadian mining companies — Red Eagle Exploration and Galway Gold — for measures taken to protect the Santurbán páramo. There are also other lawsuits filed by Cosigo Resources, South32 Investments Limited, Gran Colombia Gold, Glencore International and Anglo American in connection to other extractive projects. We call on the Colombian State to denounce the free trade agreements and bilateral investment protection agreements to which it is party and to refrain from signing such instruments in the future. It is for these reasons above that today the Comité para la Defensa del Agua y el Páramo de Santurbán (Committee for the Defense of Water and the Páramo of Santurbán) is holding a day of protest in front of the Canadian Embassy in Bogotá, demanding that ICSID respect their legitimate fight for the defense of water, Santurbán and the páramos of Colombia. Likewise, we are also in front of Congress, demanding that the Investment Protection Agreements with the United Arab Emirates-Minesa be rejected. press contacts Comité para la Defensa del Agua y el Páramo de Santurbán, [email protected], +57 3012080622 Carla García Zendejas, Center for International Environmental Law (CIEL), [email protected], +1 202 374 2550 Yeny Rodríguez Junco, Interamerican Association for Environmental Defense (AIDA), [email protected], +57 3107787601 Jamie Kneen, MiningWatch Canada, [email protected], +1(613) 761-2273 Manuel Pérez Rocha, Institute for Policy Studies, [email protected], +1 240 838 6623

AIDA applauds historic UN resolution recognizing the human right to a healthy environment
This Friday, the United Nations Human Rights Council adopted a resolution recognizing the human right to a safe, healthy, clean and sustainable environment. Getting to this point has involved decades of work by thousands of people who seek to ensure the well-being of all people and the planet we inhabit. It is now in the hands of the UN General Assembly to approve the resolution and make this human right global. Liliana Avila, Senior Attorney with AIDA’s Human Rights and Environment Program, states: "The United Nations has taken a historic step by recognizing a healthy environment as a universal right. It will strengthen the efforts of countries and peoples to protect human rights and nature, and to advance the struggle against the climate crisis. " This recognition is vital. Taking action to promote environmental and climate justice is an urgent mandate of States, and an urgent demand of the people.” Anna Cederstav, Interim Executive Director of AIDA, reflects: "Achieving this recognition at the global level has been a decades-long struggle on the part of the environmental movement, from its first mention to the present day. It is a testament to the patience and dedication necessary to promote meaningful change. We applaud all those who have made it possible: Costa Rica, Slovenia, Maldives, Morocco and Switzerland who took the lead within the UN, and all the environmental organizations, movements and individuals around the world who fight every day for a healthy planet for all." It is urgent that all States, including those that abstained from voting, recognize the importance of all people having access to clean water, clean air, and ecosystems that promote well-being and the enjoyment of human rights. AIDA welcomes this decision, which recognizes the foundational right that has guided our work since 1998. We will use the globally recognized right to a healthy environment to advance climate justice for all those who live on this planet, and those yet to come. We extend our thanks and admiration to the people who initiated this work years ago, to those who were involved in the milestones that led to the resolution, and to all of our colleagues and team members---current and past--who have worked to bring us to this day.

International technical assistance is consolidated to recover Uru Uru and Poopó lakes
At the request of organizations and communities, experts from the Ramsar Convention Secretariat will evaluate the degradation of the lakes and then issue technical recommendations for their recovery. Oruro, Bolivia. From October 11 to 15, a team of experts from the Ramsar Convention Secretariat will visit the Uru Uru and Poopó lakes, located in the central-eastern part of the Bolivian altiplano, to conduct a technical analysis of their degradation and then provide concrete recommendations to the Bolivian State for the recovery of the ecosystems. In July 2019—as part of the #LagoPoopóEsVida campaign—local communities and environmental, social and women's organizations sent the Ramsar Secretariat information on the state of the lakes and requested technical assistance to assess their health. The Bolivian government then made the formal request to make the visit feasible. "We recognize the political will of national authorities to obtain international support for the environmental crisis facing the lakes, on whose preservation the livelihoods of peasant and indigenous populations depend," said Claudia Velarde, an attorney with the Interamerican Association for Environmental Defense (AIDA). "Ramsar Advisory Missions are an effective tool offering independent and specialized advice geared toward the preservation of wetlands." Poopó is the second largest lake in Bolivia. In 2002, in order to preserve its biodiversity—which includes endemic and migratory birds and the largest number of flamingos in South America—Poopó and Uru Uru were declared a Wetland of International Importance under the Ramsar Convention, an intergovernmental treaty for the protection of these natural environments. "The Uru Uru and Poopó lakes guarantee the recharging of wells and other water sources, regulate the climate, provide habitat for birdlife, food security and sovereignty for surrounding populations, and shelter millenary cultures," said Limbert Sánchez, of the Center for Ecology and Andean Peoples (CEPA). Several factors have led to the catastrophic situation currently facing Lake Poopó, including: mining activities, which have not stopped during the pandemic and permanently generate acidic water and tons of mining waste; the diversion of tributaries like the Mauri River; the fact that the TDSP (Titicaca-Desaguadero-Poopó-Salar Water System) is not guaranteeing water for the entire basin; and the climate crisis. Cumulatively, these situations have damaged the lake and placed the life systems that depend on it at risk. "In December 2015, the water levels of Lake Poopó were completely reduced, one of the biggest environmental catastrophes in the country. Currently, what is left of the water mirror is minimal compared to historical records," corroborated Yasin Peredo, of the Center for Andean Communication and Development (CENDA). In addition to causing serious environmental damage, what’s happening to Lakes Poopó and Uru Uru is a serious violation of surrounding communities’ rights to water, health, territory, food and livelihood. "It’s with great sadness that we witness the disappearing of Lake Poopó, and the risk to our Lake Uru Uru," said Margarita Aquino, coordinator of the National Network of Women Defenders of Mother Earth (RENAMAT). "Mining contamination is stripping us of our water sources and is violating the rights of us women and our communities." Indigenous Aymara and Quechua communities depend on the health of these ecosystems, as do the Uru Murato, one of Bolivia's oldest native nations. The members of this millenary culture once lived from fishing, but the contamination of Poopó and its scarce water supply has forced them to migrate in search of other ways to survive. Don Pablo Flores, a native authority of the Uru de Puñaca community explains: "In August, authorities arrived and with them we went to the lake and found that there is no more water; the Panza Island sector is also dry. As Urus, how are we living? Before we used to go for parihuanas [Andean flamingos], but not now. In February they used to lay eggs and change their feathers. This year there are none. The flamingos are dead. The lake does not exist now. The three Uru communities are suffering; we used to live from hunting and fishing. We ask the municipal, departmental and national authorities for more attention because, so far, practically nothing has been done to save, protect and recover our lake Poopó." By including the Uru Uru and Poopó lakes as a Ramsar site, the Bolivian State committed itself to conserving the ecological characteristics of these wetlands. In this sense, the visit from the mission of experts is a key opportunity to obtain objective and specialized recommendations aimed at fulfilling this commitment. "Environmental organizations, communities and the people of Bolivia are awaiting the visit of the Ramsar Mission. We believe that the current situation of the ecosystem must be taken into account, but also the factors that continue to influence its degradation. As long as strategies to combat climate change are not adopted, mining pollution is not stopped, and the amount of water needed for the entire TDPS is not guaranteed, the critical situation of our Uru Uru and Poopó lakes cannot be reversed," said Ángela Cuenca, coordinator of the CASA Collective.
