Jbdodane / FlickrOffering communities scientific support to stop mining’s damages
Mining is an economic activity with serious environmental costs. Often, communities located near mining projects do not have access to truthful, complete and objective information on the harms and benefits of extractive industries.
This is compounded by the pollution and water depletion such activities cause in nearby rivers, lakes and other water sources. These risks often occur when mining projects are not adequately evaluated before being approved. And, too often, environmental impact assessments are not based on the best available scientific information.
Now more than ever, we must bridge the information gap between communities and the mining projects that affect them.

Watch Out! The Mining Industry Wants to Dump its Waste in the Ocean
By Florencia Ortúzar, AIDA attorney, and Karol Rodríguez, AIDA intern Mining gives rise to a serious problem: toxic waste. Tailings from ore extraction have been known to damage the environment and communities living near dump sites. Responsible management, then, is critical if we desire economic development that brings more benefits than problems. In Chile, mine companies are running out of places to dump their dangerous byproducts. Inadequate disposal has already caused substantial harm; nobody wants toxic waste near their home or community. Even depositing tailings in dry areas with low biodiversity is not safe, because rain and floods can wash contaminants into communities. In this context, Chilean mining companies have come up with the “brilliant” idea of depositing mine tailings into the sea, through a pipeline that would transport tons of waste to a valley on the ocean floor. The Ocean: delicate and mysterious cradle of life The ocean is one of the greatest mysteries on our planet. In fact, 95 percent of the ocean floor has not been mapped, which means we know only 5 percent of it. We know more about the surface of the moon than about the depths of the ocean. What’s more, oceans contain the most complex ecosystems on the planet. The variables involved in their health and dynamics are infinite. Given these unknowns, it is impossible to predict the effect that mine tailings would have on the ocean floor. This uncertainty is reason enough to apply the precautionary principle, an important legal tool to prevent environmental degradation caused by human development. We don’t know how the waste may affect complex marine ecosystems, their many species, or even ourselves, who take nourishment from fish and other seafood. So how could we sleep soundly while a pipeline funnels contaminated, and certainly hazardous, waste into our oceans? The effects of the environmental damage could be large and uncontrollable, and, once the water is released into the ocean, there would be no turning back. An international workshop on the idea To understand more about this worrying initiative, two renowned Chilean environmentalists—Juan Pablo Orrego, president of Ecosistemas, and Flavia Liberona, executive director of Fundación Terram—attended an international workshop in Lima in June. Participants at the workshop, convened by the Joint Group of Experts on the Scientific Aspects of Marine Environmental Protection and the International Maritime Organization, discussed the viability of depositing mine tailings in the ocean. Orrego penned an article on the theme, which you can read here. In the workshop they learned that dumping mine waste into the ocean is nothing new. It happens in Canada, Turkey, Papua New Guinea, and in some African countries. The Norwegian government recently authorized the use of a pristine fjord (a narrow sea inlet) as a repository for mine tailings from a rutile mine. During the workshop, an official from the Norwegian government defended the decision, arguing, “The social benefits from the mine outweigh the destruction of the fjord.” According to whom? For and against Supporters of the Chilean proposal claim that dumping tailings into the sea does not necessarily entail a hazard. They say the risks are minimal because there’s no oxygen on the bottom of the ocean, so the chemical reaction that causes toxicity on the surface would not occur. Leonel Sierralta J., former official of Chile’s Environmental Ministry and current scientific director of Sustainable Initiatives for Mining, penned an open letter in response to Orrego’s article. In it, he says that although there have been disastrous cases involving mine waste in the ocean, there are also cases in developed countries in which waste dumping has been carried out based on science and following strict environmental criteria. His arguments have not convinced those who oppose the proposal, including five Chilean senators who sponsored a bill to prohibit the discharge of tailings into the ocean. An alternative: neutralize the risk Orrego proposes to regulate mining more strictly. He says that before tailings are deposited, mining companies must extract from them all heavy metals and neutralize their chemical compounds. In that way, it would be feasible to deposit practically inert tailings in places such as old mine shafts. It would even create an economic opportunity for companies to begin extracting and recycling dangerous elements. The neutralization of tailings is an appropriate alternative to continuing environmental destruction. Orrego’s proposal is sensible. It’s reasonable to assert that economic activities dangerous for the environment continue only if their impacts are neutralized. If we generate more waste than we can deal with, it’s because we are not acting sustainably, which means we are not assuring the conservation of a healthy planet for our descendants. This is why we at AIDA work daily to preserve the health of ecosystems in the face of highly polluting activities like mining.

Guidelines for the Environmental Impact Assessment of Mining Projects
For many communities, water is a scare and therefore valuable resource. Access to it is complicated if rivers, lakes, or other sources are polluted or overused. Water quality often suffers when the impacts of mining projects are not adequately evaluated before the mines are authorized. AIDA’s legal expertise is helping to prevent or minimize mining’s damage on the environment and on the people who depend upon it. In collaboration with scientists and experienced technicians, we’ve prepared a guide detailing the comprehensive analysis that must be completed for any Environmental Impact Assessment of a proposed mining project. The guide will be as useful to authorities as to communities and civil society organizations. This guide recommends that, in all its sections, the Environmental Impact Assessment of a mining project contain detailed information that addresses everything from general aspects of the project to its social and environmental impacts, as well as measures to prevent or mitigate them.

Pilcomayo: El río de los pájaros herido por la minería
By Ariel Pérez Castellón, lawyer AIDA For hundreds of years, the Pilcomayo has been essential to the life of at least twenty indigenous peoples living in the river basin, which covers the territories of Bopvia, Argentina and Paraguay. Among these people are the Guarani, Weenhayek, Toba and Wichi. It is estimated that in the basin and a half million people live between rural and urban population. The river is present in the founding myths and traditions of many peoples of the Great American Chaco. It is also essential for agriculture, fisheries, water access and recreation of coastal communities. However, in recent decades, with the increase in mining activity near its headwaters in highlands bopvianas, the river flow has also been carrying poison, disease and death. Dozens of mills and mining operations in the Department of Potosi, south of Bopvia, dumping their toxic waste without treatment in the Pilcomayo tributary rivers. Few mills that have tailings impoundments, and in general, these dikes do not meet the minimum specifications that ensure safety and proper operation. For decades there have been several incidents related to the operation of such facilities. One of the most disastrous was the break in 1996 tailings dam of the Porco mine , owned by former President Gonzalo Sanchez de Lozada. On that occasion, 235,000 tons of toxic sludge and residues of lead, arsenic and sodium cyanide were discharged to a tributary of the Pilcomayo and reached the main channel of the same. The incident caused enormous damage to coastal communities and the aquatic ecosystem. Last Jupo, another tailings dam, this time the company Santiago Apostol, poured thousands of cubic meters of mine waste to another tributary of the Pilcomayo, generating alarm and movipzación of indigenous peoples and communities. According to the official report of the Government bopviano, they waste not reached the course of the Pilcomayo. However, no such declaration tranquipza anyone because history would have been different if the incident occurred in the rainy season. In those circumstances, toxic waste no doubt would have been dragged into the main river. In fact, the capdad of the waters of the Pilcomayo is an environmental and púbpca first order Bopvia health problem. Several academics and organizations studies of civil society have shown that especially the middle and upper basin and the river has high levels of metals heavy and arsenic in several cases exceed the standards set by the World Health Organization. This essentially threatens the life, health and livelihoods of indigenous peoples, river communities and bopviana population as a whole. Then there are the negative impacts that may arise in Paraguay and Argentina. Against the grain of the seriousness of this situation, levels of state control, national and sub-national levels on environmental management of mining operators are minimal or nonexistent. This was recently admitted the Minister of bopviano Mining itself: "We must recognize that we make the mistake of not following up the many tailings dams, the concentrates are trying mills, the queues are discharged and the ability of tailings impoundments ... ". Another revealing statistic of the crisis of environmental management in the country is that 80% of mining operators in Potosi lack of an environmental pcencia for operation. Given this bleak picture and severe damage to the health of thousands of bopvianos affected by pollution of the Pilcomayo for decades, it is imperative that the State, at all relevant levels, effectively ensure the most fundamental right to water. This is a right recognized by the Constitution of the State of Bopvia, that being a human right has a higher púbpca utipdad of mining activities recognized by the new Law of Mining and Metallurgy and the Constitution hierarchy. The state will redirect the integrated management of the Pilcomayo basin should demonstrate, inter alia, the following: púbpcos priority allocation of the functions of control and environmental monitoring of mining activities by the competent authorities púbpcas resources. Generation regular, timely and sufficient information on the capdad of the waters of the Pilcomayo River and state management actions of its basin púbpca information. Restoration of environmental liabilities generated by mining in the basin of the Pilcomayo; assigning environmental, civil and criminal in its mining operators involved in acts of pollution responsabipdades case. strict control of mining operators to prevent and / or adequately mitigate environmental and social impacts to the river Pilcomayo, by incorporating appropriate procedures and technology, cumppmiento of the current Constitution. Pilcomayo word comes from the Quechua words phisqu (bird) and mayu (river). It is the river of birds. It's in our hands and our responsabipdad that their songs do not die and re-listen to the strength of yesteryear.
