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.

My first visit to La Oroya
By Rodrigo da Costa Sales, AIDA attorney “What do you think of La Oroya?” a local resident asked me the first time we met. Honestly, I wasn’t quite sure how to respond. Quickly sensing my discomfort, he joked, “It’s very beautiful, there’s so much biodiversity, and the sky is so blue...” Relieved, I laughed along with him and, since that moment, I’ve been searching for the words to describe La Oroya. La Oroya is a city of 33,000 people on the Mantaro River in central Peru, at an altitude of nearly 5,000 meters. This was my first time there, and I stayed only two days. The trip from Lima takes five hours, winding along painfully curvy roads with breathtaking views of the mountains all around. In La Oroya, however, the landscape changes drastically. The city is covered in a sheet of grey, with little to no natural life, streets full of trucks transporting iron and other heavy metals... and not much else of note. My greatest wish for my time in La Oroya was to meet the people we are representing in our case before the Inter-American Commission on Human Rights. After working on it for six months, I wanted finally to put faces to the names I had come to know so well on paper. Our meeting was scheduled for the evening, when residents could find time free from work and family commitments. There, we introduced them to students from Yale University, who were developing an important report on the relationship between La Oroya’s air quality and the health of city residents. Although interested in the study, and happy to hear about it, residents quickly peppered us with questions about the case. The main thing they wanted to know—an answer they have been waiting for since our petition was filed seven years ago—was when the Commission will make its decision. They explained the many offensive comments they’ve had to endure, both from workers at the metal-smelting complex and from their own neighbors, during the long wait for a ruling. They’ve suffered threats from fellow residents of La Oroya, who wrongfully believe that the purpose of the case is to close the complex, which would leave many people without jobs. In one especially disturbing instance, a “doctor” spoke on television claiming that lead contamination does not cause any health problems. He claimed the residents of La Oroya as proof that, while contaminated by lead and other heavy metals, people could still lead normal lives. We reminded them that a process before an international organism involves years of waiting, and that we sympathized with them for everything they had been through in the past few years. But the truth is that I felt such intense frustration. It was the first time that I saw, up close, such personal desire for an international decision. I understood then that a decision on paper could actually constitute a form of reparation. The long-awaited Commission report will show the world that the effects of heavy-metal pollution on a population actually violate their personal integrity and right to health. The goal of this case is not to close the metallurgical complex, but instead to force the adoption of measures that guarantee a certain quality of life for the residents of La Oroya. The Commission’s report will be the instrument in this case by which international and human rights law becomes real, effective and transformative. I returned from La Oroya almost a week ago, and I’m still searching for the words to describe such a place. Truthfully, La Oroya didn’t seem very nice at first. But I quickly came to realize that the beauty of a place comes not only from its natural and man-made attractions; it comes also, and perhaps more importantly, from the beauty of its people. In that sense, I’ve never seen a city quite as beautiful as La Oroya. This blog is dedicated all the victims of the case in La Oroya. I hope that they will achieve justice, and that because of them, a case like this is never repeated around the world. It is also dedicated to Astrid Puentes and Maria José, AIDA’s attorneys in charge of the La Oroya case, who inspire me daily to work for a more just world.

Still Waiting for Justice in La Oroya
Part 1 of a 2-Part Series on the Human Rights Situation in La Oroya, Peru. By María José Veramendi Villa Juana[1] is tired. She and her neighbors have been waiting eight years for a ruling; eight years for a decision that could better their lives, clean their air, attend to their sick children and families. What began as a courageous and hopeful quest for justice has become a discouraging waiting game. Since 2007, a group of residents in La Oroya, Peru, has acted as petitioner in a case before the Inter-American Commission on Human Rights, Community of La Oroya v. Peru. For nearly a century, their city has been contaminated by the operation of a metallurgical complex (smelter) within its borders. The smelter has blackened the air, poisoned their bodies, and released toxic chemicals into the land and water. La Oroya was once identified as one of the most polluted cities in the world. The severe contamination has, and continues to have, grave impacts on the health of the city’s residents. Realities of La Oroya When AIDA’s co-executive director Anna Cederstav first arrived in La Oroya in 1997, women were walking around with scarves covering their faces, a vain attempt to ease the pain of breathing. Juana explained that she had felt the steady burning in her eyes and throat—the effects of contamination—since she could remember, but didn’t pay it any mind. Like most of the population, she thought it was normal. She didn’t really know what clean air was because she’d never experienced it. AIDA has worked for nearly two decades with the community of La Oroya. In 2002, we published the report La Oroya Cannot Wait with the Peruvian Society for Environmental Law. That report began to reveal to the community the severity of the pollution and health risks they were facing on a daily basis. The community realized they had to do something. Juana said it was in 2003, more than 80 years after the smelter began operating, that she became aware of the contamination. Through work with her parish, she was able to access information and learn about what was happening in her city. From there, she connected the dots—the respiratory problems in her family were, in fact, a result of her city’s extreme contamination. The quest for justice Residents submitted their case before the Inter-American Commission after their attempts at justice within Peru produced no remedy. A 2006 ruling by Peru’s Constitutional Tribunal against the State ordered it to adopt measures to protect the health of the community, but the State took no such action. In 2007, the Commission urged the Peruvian state to carry out precautionary measures—a specialized diagnosis of 65 residents and treatment for those who showed irreversible damage to their lives or personal integrity. Juana said receiving news of the precautionary measures was a happy moment because “we knew that we were winning something. At the beginning, everything went well and we believed that everything would be fixed, (but) with the passing of months—years—there were no answers.” Then, in 2009, the Commission issued a report admitting AIDA’s petition, declaring that the State’s omissions in the face of pollution could, if proven, represent human rights violations. But still, nearly a decade after the petition was first filed, the victims await a decision, the precautionary measures have yet to be enforced, and the State’s responsibility for the acts have yet to be established. “It’s taking a really long time, and not all of us have the patience or desire to keep waiting,” Juana said. Time affects the victims, wearing them out until they begin to waver and give up fighting for their right to justice. They become even more vulnerable as they face a city hostile to anyone who fights for their rights to life and health, a state that denies its responsibility and looks for any excuse to avoid assuming responsibility, and a company that wants to polish its reputation and use its economic power to manipulate the government. Where is the law in these cases? Where is justice? Juana explained that leaving La Oroya would be impossible for her family, because there they have work. She remains committed to achieving change with the lawsuit. But that’s not the case for everyone. La Oroya contains thousands of stories of families whose lives were radically changed due to the city’s contamination and the subsequent damages to their health and lives. There are those who had to abandon their homes because they did not see a future in the city, and those who have been unable to leave La Oroya because their entire lives and family are there. Then there are those who have suffered painful attacks and insults from their own neighbors in a community worried about losing jobs, but who march forward with the conviction that, one day, change will come and La Oroya will be a better and fairer place for them, their children, and their grandchildren. I trust and hope that the law will deliver justice to salvage those years of waiting. [1] The name has been changed to protect the client.

Indifference to life and health in Peru
By María José Veramendi Villa, @MaJoVeramendi In Peru, every year around 400 children die of cold. I learned this dramatic figure a few weeks ago when I read a column titled “Dying from Indifference,” by Congresswoman Veronika Mendoza. I asked with genuine indignation: How is it possible that children could die of cold in a country that prides itself on its mineral wealth, its great attraction for foreign investment, its tourism and culinary strengths? A country that hosts major world events such as the Conference of State Parties to the UN Framework Convention on Climate Change? Besides the lack of political will from our leaders, who worry more about looking good in photos taken at grand events, the answer can be found in a key paragraph of Mendoza’s column: “Where could such political will come from if no one is moved, if no one is indignant that these children die, perhaps because they tend to be “somewhere else,” usually peasants, who often speak Quechua or Aymara?” Regret before prevention On July 18, 2015, the government issued a supreme decree that declared a state of emergency in some districts and provinces of the country, due to frost. The first paragraph of the decree states that “every year and on a recurring basis, between the months of May and September, our country experiences weather events related to low temperatures, such as frost in our highlands, as was observed in recent seasons with extreme temperatures well below 0 ° C ...” If these weather events occur every year, why not prevent their impacts? In 2004, information from the Tyndall Centre, University of Manchester, revealed that Peru is the third most vulnerable country to the effects of climate change, the main cause of such phenomena as increasingly intense frost. Indifference to the violation of human rights Indifference in Peru not only manifests itself in children dying of cold in remote communities, but also La Oroya, a city only 175 kilometers from Lima. In a context of extreme industrial pollution, the population, including children, has for many years suffered violations of the rights to life and health. On August 11, a strike organized by the workers of the metallurgical complex in La Oroya, and the subsequent closure of the main highway that provides access to the center of the country, set off alarm bells in the city. Not bells that should sound when pollution limits are exceeded, but those of a long-neglected social demand. The metallurgical complex, owned by the company Doe Run Peru, is for sale and in the process of liquidating. According to information released to the public, no interested party submitted a financial offer because Peruvian environmental standards are too strict. In response, the workers took control of the road, demanding that the State relax those standards so the complex can be sold and they retain their jobs. The protest left one dead and 60 wounded. It ended after the signing of a five-point agreement, which does not mention the rights to life and health of the population of La Oroya. In a city that has been subjected to unchecked contamination for more than 90 years, Doe Run Peru has continued to obtain extensions to meet its environmental obligations. In July 2015, the company obtained a further extension of 14 years for the complex to meet environmental standards. But what about the life and health of the people? The State has not seen that environmental standards are met in La Oroya. Neither has it fully safeguarded the health of its inhabitants: • The air quality alert system has not been activated properly. • The doctors in charge of health and the heavy metals strategy are scarce and face the constant risk of running out of resources to continue working. • The State insists on asking the Inter-American Commission on Human Rights to lift the measures ordered in 2007 to protect the lives and health of a group of La Oroya residents. Speaking Loudly Children are as vulnerable to cold as they are to the effects of industrial pollution. However, the State only comes to their aid in times of crisis or when it is too late. It sounds like a cliché, but children are our hope. Let us listen so they don’t die of cold and are no longer poisoned! Otherwise, we will also be victims of the disease of indifference.
