#tailings

2025-11-18

In the distant 2016, when I was a member of an environmental NGO in Kryvyi Rih (Ukraine), I started using satellite Earth Observation data to monitor the condition of large industrial tailings ponds.

At that time, environmental regulations required these storage facilities to be either flooded or at least kept moist to prevent dust storms.
Industrial operators often ignored these rules, leaving huge dry surfaces exposed — which created massive dust pollution affecting nearby communities.

Using Sentinel-2 and Landsat-8 imagery with false-color composites, I developed a simple but effective method to map dry, moist, and water-covered zones of tailings ponds.

Local residents and journalists were absolutely delighted! Industrial companies, on the other hand… reacted very differently 🤣

These maps are from 2016–2017 and show several tailings facilities around #KryvyiRih.

At What Cost

dams have a sinister beauty – the colours are extraordinary. They often contain waste materials, such as toxic chemicals and heavy metals, which can harm birdlife and ground water.

It’s estimated that there are about 18,000 tailings dams around the world.

Opinion: Why the birthplace of the Western #Apache religion shouldn’t be destroyed by a #CopperMine

by Luke Goodrich
February 6, 2024·

"A federal court is poised to decide whether a #NativeAmerican #sacred site will be destroyed by a massive #copper #mine. Mining proponents claim that destroying the #SacredSite is necessary for the development of #GreenEnergy. That claim is both factually wrong and morally repugnant. And recent polling shows that the vast majority of Americans agree with what the constitution requires: #Native sacred sites deserve the same protection as all other houses of worship.

"Since before European contact, #WesternApache and other Native tribes have lived and honored their #Creator at #OakFlat, or 'Chi’chil Bildagoteel.' The site is the birthplace of Western Apache religion and the site of ancient religious ceremonies that cannot take place anywhere else. Because of its religious and cultural significance, Oak Flat is on the National Register of Historic Places and has been protected from mining and other destructive practices for decades.

"That changed in 2014, when several members of Congress, supported by #corporate #mining #lobbyists, slipped an amendment into a must-pass defense bill authorizing the transfer of Oak Flat to a foreign-owned mining giant. That company, #ResolutionCopper, announced plans to obliterate the sacred ground by swallowing it in a mining crater nearly two miles wide and 1,100-feet deep, ending Apache religious practices forever. That was no surprise given the company’s sordid history dealing with #IndigenousPeoples. The majority owner of Resolution Copper is #RioTinto (the world’s second largest mining company), which sparked international outrage in 2020 when it destroyed a 46,000-year-old rock shelter with some of the most significant #Aboriginal artifacts in all of #Australia.

"The Apache and their allies, represented by my firm, the #BecketFundForReligiousLiberty, have been fighting in court to ensure that such an atrocity won’t repeat itself at Oak Flat. After initial court rulings against the Apache, a full panel of 11 judges at the Ninth Circuit Court of Appeals reheard their appeal last spring. A decision on whether the government can execute the land transfer is expected any day.

"Resolution Copper and its backers want the public to believe that building the mine is essential for developing #renewable energy. Extracting the copper beneath Oak Flat, they say, will help to build batteries necessary for powering #ElectricVehicles and thus fight #ClimateChange. In other words, we have to destroy Oak Flat in order to save the planet.

"These claims, however, are false — and they are specifically designed to obscure the physical and cultural destruction the project would wreak on the land.

"The mine will destroy the #environment, not save it. It is undisputed that the mine will swallow the ecologically diverse landscape of Oak Flat in a massive crater, decimating the local #ecosystem. It will also leave behind approximately 1.37 billion tons of '#tailings,' or #MiningWaste, which, according to the government’s own environmental assessment, will pollute the #groundwater and scar the landscape permanently. And the mine will consume vast quantities of water at the time it is most needed by drought-stricken towns and #farmers.

"Supporters of the mine are also at odds with the majority of Americans. According to this year’s Religious Freedom Index, an annual survey conducted by Becket, 74% of Americans believe that Native sacred sites on federal land should be protected from mining projects, even when the projects are purportedly pro-jobs and pro-environment.

"That conclusion is both sensible and humane. America can transition to renewable energy without blasting the cradle of Western Apache religion into oblivion. And it should. For too long, our nation has made excuses for taking advantage of #IndigenousPeople and their land. Indeed, our nation drove the Western Apache off Oak Flat and surrounding lands in the 1800s precisely to make way for #MiningInterests. It shouldn’t repeat that #injustice again.

"It is past time to protect Indigenous sacred sites from further destruction. Basic fairness and our constitutional commitment to religious freedom require no less. And, happily, most Americans agree."

Polluter Pay Alberta Garbage Day
October 28, 2023
Alberta Legislature
To protest the Alberta government’s lack of action on holding resource extraction industries responsible for their pollution. Tailings ponds from tar sands extraction now spread over an area larger than metropolitan Vancouver. Recent tailings leaks from the Imperial Oil Kearl site went unreported for months.
