Johannesburg’s Golden Legacy Includes Radioactive Dump Featured

Johannesburg sits atop the world's most productive gold reef -- a staggering 40,000 tons of the precious metal has been mined from it during a history tracing back 130 years. That legacy of riches has left behind a toxic inheritance: radioactivity from uranium hauled up in the mining process.
Scientists have found uranium quantities in rivers west of the city to be as much as 4,000 times natural levels and in tap water as much as 20 times higher. A soil sample taken by Bloomberg News and tested by government-certified WaterLab Ltd. from pumpkin roots grown a little more than a mile from a recently closed gold mine contained five times more uranium than background levels considered normal by the International Atomic Energy Agency.


Residents of Johannesburg and surrounding communities live among an estimated 600,000 metric tons of uranium buried in waste rock and covering an area four times the size of Manhattan, according to university researchers. Another undetermined amount lies below ground, where water has filled abandoned mines and leaks into the environment.
"There's nowhere in the world where you'll find so many people living alongside such a vast amount of ore-bearing uranium," said Carl Albrecht, head of research at the Cancer Association of South Africa, or Cansa. "There are 400,000 people in the area who are subjected to this environment and yet the government is unwilling to consider the health impact."

Health Threat

Government regulators and health advocates disagree over the public-health threat this poses. Albrecht and others point to U.S. Environmental Protection Agency data that says even low-level radiation exposure, if prolonged, can lead to an increased rate of cancers. Susan Shabangu, minister of South Africa's Department of Mineral Resources, said levels recorded in and around Johannesburg are "a cause for concern" but not yet a "level of danger."
One thing is indisputable: the amount of untreated waste material containing uranium is growing as a 28 percent plunge in the gold price last year has shuttered mines and increased the number of abandoned mine sites. The Blyvooruitzicht mine 50 miles (80 kilometers) southwest of Johannesburg -- near where the Bloomberg News soil sample was taken -- was closed in July, throwing 1,700 miners out of work.
The mine's last operator, Village Main Reef Ltd., isn't responsible for the environmental rehabilitation of the mine because it never took legal ownership of the operation, according to Chief Executive Officer Ferdi Dippenaar.
Village operated the 72-year-old mine for 18 months, he said.
'Within Limits'
"As far as I am aware, and based on tailings recoveries, the content of uranium during this time was definitely within limits," Dippenaar said. Tailings refers to waste material. Village has no plans to reopen the mine and it's currently being liquidated, he said.
Unmaintained, abandoned dumps lose their shape as their toxic material seeps into the surrounding area, said Anthony Turton, a professor at University of the Free State's Center for Environmental Management. When waste dumps, known as tailings dams, are abandoned "you get major erosion taking place and slides of toxic material into wetlands," he said.
While South Africa has required companies to set aside money for environmental mitigation since 1994, "the reality is the funds set aside for environmental liabilities are totally insufficient," Turton said.

Cleanup Costs

South Africa will be forced to spend about $2.7 billion on cleaning up its nearly 6,000 abandoned mines, the World Wildlife Fund said in a 2012 report, citing the country's auditor general. Of the country's working mines, almost 40 percent don't have adequate funds available for rehabilitation, according to the Department of Mineral Resources' 2012-2013 annual report.
The effects of low-level, chronic exposure to radiation include cancer and changes to DNA, known as mutations, that can be passed onto offspring, according to the U.S. government. High uranium intake over time can also lead to increased cancer risk and liver damage, the agency said.
For every ton of ore mined, South African produces between 3 grams (0.1 ounce) and 15 grams of gold, meaning most rock removed from the earth is waste material, and contains toxic chemicals including uranium, mercury, radon, arsenic and sulfuric acid.
The upside of gold mining here is well known. The industry stretches back to 1886 and among its pioneers was German immigrant Ernest Oppenheimer, who founded Anglo American Plc and helped to turn Johannesburg into Africa's richest city. Mining helped make fortunes not just for the Oppenheimers but for Cecil John Rhodes, the first chairman of DeBeers, and current billionaire Patrice Motsepe, founder of African Rainbow Minerals Ltd.

Unsightly Legacy


That legacy's unsightly side is in plain view here. Waste rock from hundreds of mines that have been developed over the years has been deposited around Johannesburg in mounds that cover a combined area of 400,000 square kilometers and can be as many as 10 stories high. One such dump, which looks like a flat-topped sand mountain, sits next to the FNB Stadium, where the final of soccer's World Cup was played in 2010.
The tailings contain about 600,000 tons of uranium, three times the amount exported during the Cold War, according to Professor Frank Winde at South Africa's North-West University. It's getting into the water supply, according to Winde, a German-born scientist who has studied the effect of uranium on South Africa's environment for 30 years and overseen university testing for radiation levels.

Dissolving Metal


This happens in a variety of ways, according to Winde. The radioactive metal dissolves in rainwater and runs off the dumps into rivers during storms or is carried into water sources when it seeps through porous rock as abandoned mines are flooded. It can also be spilled by companies that re-mine dumps for the metal. Dust clouds containing uranium form when high winds hit the dumps.
Soil taken by Bloomberg News from pumpkin roots about 100 meters away from Wonderfonteinspruit, a stream feeding the Vaal River and close to Blyvooruitzicht, was found to contain 10.4 milligrams of uranium per kilogram. That's five times higher than the 2 milligrams per kilogram average, according to the IAEA.

'No Threat'


Shabangu, the mineral resources minister, says the levels aren't cause for alarm.
"Scientifically, it has been proven we're not at a level that poses a health threat to communities," she said in an interview.
Winde disagrees. "We have generally underestimated the presence of uranium in the water supply," he said. "If the government has a study saying it's safe then I would like to see it. As far as I'm aware, nobody has studied whether it has an impact on general health, on the likelihood of cancer, on hormonal functions, on DNA" in South Africa.
Two hours west of Johannesburg's business district of Sandton lies Khutsong, a township of 60,000 from which the soil sample was taken. Residents there struggle daily for water, electricity and work.
Two-bedroom brick houses built by the local government are surrounded by improvised shacks with corrugated iron roofs. Jobs are scarce after gold mines, including Blyvooruitzicht, were closed.

No Choice


While the government prohibits people from drinking, irrigating and washing in water taken directly from rivers, for thousands living in an area known as the West Rand there is no choice, said Sello Mokoena, 27, a worker on the vegetable patch in Khutsong.
"People tell us that the water is polluted from the mines but we have nothing else," said Mokoena, wearing a green sports shirt and orange trousers. He earns about 700 rand ($63) a month working on the vegetable patch and herding livestock, and uses it to support his mother, three brothers and a sister.
The Bloomberg soil sample was taken from an area suspected of containing mine waste and was not part of a scientific study. No vegetables picked from the patch by Bloomberg News were found to contain elevated levels of uranium.
Joe Maila, a spokesman for South African Health Minister Aaron Motsoaledi, referred questions to West Rand District Municipality. The municipality is "concerned with all activities which may have a negative impact on public health," Cheleng Khotle, a manager for municipal health, said in a statement. "The municipalities may currently not be able to provide funding" for further studies. "Continued technical monitoring is encouraged and would be supported by municipalities through participation."

Elevated Levels


Water samples from Wonderfonteinspruit show uranium levels on average 400 times background levels, and reaching as high as 4,000 times, according to Winde, who compiled a series of studies he and other scientists have done over the past 20 years.
Winde detected uranium levels of 53 micrograms per liter at the Boskop Dam, which supplies Potchefstroom, a town 75 miles west of Johannesburg and about 25 miles southwest of Blyvooruitzicht, in November 2012. That indicates 21 micrograms per liter of uranium in tap water sourced from that dam, 40 percent higher than the World Health Organization's safe level of 15 micrograms per liter, he said.
While that was a one-time test and exceeded usual tap-water readings of about 5 micrograms per liter in Potchefstroom, below the safe level, it shows that residents are sometimes exposed to dangerous water quality, said Winde, who lives in the town and doesn't drink the water.

Water Safety


Wonderfonteinspruit, Carletonville, and Potchefstroom are towns in the West Rand, downstream from Johannesburg and the mine-waste dumps. The metropolis's water supply isn't contaminated because it comes from the upper part of the Vaal River and from nearby Lesotho, a landlocked mountainous kingdom surrounded by South Africa.
Tap water in the West Rand including Potchefstroom is safe to drink, according to Marius Keet, senior manager at the Department of Water Affairs.
"At the moment there's no danger there," he said. "We're in contact with the scientists there and there are concerns -- not now, but in the future -- if there is a slow increase of uranium in the feed water."
People shouldn't drink water directly from rivers, such as Wonderfonteinspruit, dams or seasonal streams in the area, Keet said.
"You're not allowed to take water from any river in South Africa," he said. "For as much as uranium is a challenge, there's also the challenge of bacteria."

Unprecedented Exposure


South Africa is unique among gold-mining countries because of the dense population that has grown up around its mines. That means exposure to low levels of uranium over a long period of time is unprecedented and should be investigated by the government, according to Cansa's Albrecht.
In 2011, Cansa found uranium levels in two Carletonville residents' teeth that were as many as 100 times higher than a 2007 study that took the same measurement from people living in a Brazilian mining area.
The Department of Water Affairs' Keet said he's in favor of studying the effect of low levels of uranium intake over long periods of time on people's health. The Department of Health should conduct such research, he said.
His major concern is uranium seeping from the mine dumps through dolomitic rock, which is porous, and into the water table. "That will have to be well monitored in the future," he said.

Mines' Responsibility


The government's long-term approach to remove uranium from mine dumps is to allow companies to re-mine them for gold, eliminating toxic wastes as they go. A number of companies are already doing that, among them AngloGold Ashanti Ltd., DRDGold Ltd. and Mintails Ltd.
DRDGold, which doesn't mine in the West Rand, said this process is "enormously" helpful because it removes waste and deposits it in modern tailings complexes under the scrutiny of regulators. Mintails is "proud to be playing a leading role" in removing hazardous materials from "potentially the most uranium contaminated landscape in the world," said Turton, who acts as an adviser to the company.
While re-mining can be part of a solution to uranium pollution, it's also part of the problem, according to Mariette Liefferink, CEO of the Federation for a Sustainable Environment.
"Cost-cutting and disregard for the environment mean there are radioactive spillages every few weeks in the West Rand," she said. "Unless these mining companies mine cleanly, they will only make the situation worse."

Environmental Incidents


AngloGold was responsible for 10 environmental incidents it classified as "significant" in South Africa in 2012, according to the company's annual report. They involved toxic waste being spilled onto farmland and in rivers. Of the 10 incidents, seven were attributed to Mine Waste Solutions, which re-mines waste material and was bought for $335 million from First Uranium Corp. two years ago.
The company has spent about $90 million upgrading Mine Waste Solutions since the acquisition and has improved its water monitoring, pipeline maintenance as well as creating so-called containing areas for potential spills, CEO Srinivasan Venkatakrishnan said in an interview.
Winde, who is attempting to raise money for further research, says the companies and government aren't doing enough.
"We know there are elevated levels of uranium from years of gold mining all over the West Rand but what we don't know is how much worse it will get as mines close and what the health implications are," he said. "Given the magnitude of the problem, there's a complete lack of action to address it."

Radon Alert - Carte Blanche

Millions of South Africans are exposed to radioactive radon gas in their homes and workplaces every day, as the naturally occurring gas escapes through cracks in the earth. The second leading cause of lung cancer in several countries, radon breaks down and when inhaled, decaying atoms emit alpha radiation that can damage the DNA. There are no safe levels of radon concentration. The United States Environmental Protection Agency emphasises any radon exposure has some risk of causing lung cancer. Carte Blanche investigates why South Africa has no regulations to protect against radon accumulation in the home and what you can do to test your home and prevent lung cancer.   Watch the video here.

Mining activists in SA face death threats, intimidation and harassment - report

SATURDAY STAR | 19 APRIL 2019, 7:41PM | SHEREE BEGA Picture:Yvette Descham On August 13 2013, Billy M heard gunshots at the gate of his house. He didn't know who fired the gun, and, worried that local traditional leadership might be involved, he didn't report the incident to the police. For the next five years, the community activist from Fuleni, a small rural village in KwaZulu-Natal bordering one of SA's oldest and largest wilderness areas, the Hluhluwe iMfolozi Park, continued to receive threats.  "We know our lives are in danger. This is part of the struggle," he says, simply. Billy M's account is contained in a new report released this week, 'We know Our  Lives Are in Danger’: Environment of Fear in South Africa’s Mining-Affected Communities, which documents how community activists in mining areas face harassment, intimidation and violence. The report details how in Billy M's case, mining company Ibutho Coal had applied for rights to develop a coal mine in Fuleni in 2013. The development would have required the relocation of hundreds of people from their homes and farmland and destroy graveyards. "The mine's environmental impact assessment estimated that more than 6000 people living in the Fuleni area would be impacted. Blasting vibration, dust, and floodlights, too, could harm the community," says the report."During the environmental consultation processes, Billy M led opposition that culminated in a protest by community members in April 2016."The company reportedly abandoned the project in 2016 while another firm, Imvukuzane Resources is reportedly interested in mining in the area.The 74-page report, compiled by Human Rights Watch, the Centre for Environmental Rights (CER), groundWork, and Earthjustice, describes a system designed to "deter and penalise" mining opponents.The authors conducted interviews with more than 100 activists, community leaders, environmental groups, lawyers representing activists, police and municipal officials, describing the targeting of community rights defenders in KwaZulu-Natal, Limpopo, Northwest, and Eastern Cape between 2013 and 2018. They report intimidation, violence, damage to property, the use of excessive force during peaceful protests, and arbitrary arrest for their activities in highlighting the negative impacts of mining projects on their communities. "The attacks and harassment have created an atmosphere of fear for community members who mobilise to raise concerns about damage to their livelihoods from the serious environmental and health risks of mining and coal-fired power plants," write the authors."Women often play a leading role in voicing these concerns, making them potential targets for harassment and attacks."But municipalities often impose barriers to protest on organisers that have no legal basis while government officials have failed to adequately investigate allegations of abuse."Some mining companies resort to frivolous lawsuits and social media campaigns to further curb opposition to their projects.  The government has a Constitutional obligation to protect activists," write the authors. Picture: Shayne Robinson, Section 27 Authorities should address the environmental and health concerns related to mining "instead of harassing the activists voicing these concerns,” remarks Matome Kapa, attorney at the CER.The report starts with the high-profile murder of activist Sikhosiphi “Bazooka” Rhadebe, who was killed at his home after receiving anonymous death threats in 2016. Rhadebe was the chairperson of the Amadiba Crisis Committee (ACC), a community-based organisation formed in 2007 to oppose mining activity in Xolobeni in the Eastern Cape.  "Members of his community had been raising concerns that the titanium mine that Australian company Mineral Commodities Ltd proposed to develop on South Africa’s Wild Coast would displace the community and destroy their environment, traditions, and livelihoods. More than three years later, the police have not identified any suspects in his killing."Nonhle Mbuthuma, another Xolobeni community leader and spokesperson of the ACC, has also faced harassment and death threats from unidentified individuals. "I know I am on the hit list.… If I am dying for the truth, then I am dying for a good cause. I am not turning back," she says.But other mining areas have had experiences similar to that of Xolobeni. "While Bazooka’s murder and the threats against Nonhle have received domestic and international attention, many attacks on activists have gone unreported or unnoticed both within and outside the  country."This is, in part, because of "fear of retaliation for speaking out, and because police sometimes do not investigate the attacks", the authors found.The origin of these attacks or threats are often unknown. "So are the perpetrators, but activists believe they may have been facilitated by police, government officials, private security providers, or others apparently acting on behalf of mining companies. "Threats and intimidation by other community members against activists often stem from a belief that activists are preventing or undermining an economically-beneficial mining project. In some cases, government officials or representatives of companies deliberately drive and exploit  these community divisions, seeking to isolate and stigmatize those opposing the mine."The Minerals Council South Africa, which represents 77 mining companies, including some in the research areas, responded that it “is not aware of any threats or attacks against community rights defenders where (its) members operate”.The authors state that while the mining sector and the government emphasise how mining is essential for economic development, "they fail to acknowledge that mining comes at a high environmental and social cost, and often takes place without adequate consultation with,or consent of, local communities".The absence of effective government oversight means that mining activities have harmed the rights of communities across South Africa in various ways. "Such activities have depleted water supplies, polluted the air, soil, and water, and destroyed arable land and ecosystems."Researchers also documented cases of police misconduct, arbitrary arrest, and excessive use of force during protests in mining-affected communities, "which is part of a larger pattern in South Africa".Last year, the Centre for Applied Legal Studies (CALS) at Wits University documented various efforts by traditional authorities to stifle opposition to mines in their communities. "In some cases, traditional authorities label those opposing mines as anti-development and troublemakers, thus alienating and stigmatising them.As a result, community members are often afraid to speak out against a mine in open consultations," CALS found.Research by the SA Human Rights Commission, too, has found that community members sometimes “are afraid to openly oppose the mine for fear of intimidation or unfavourable treatment (by the Traditional Authority)."The SAHRC says many mining-affected communities are experiencing “the creation of tension and division within communities as a result of mining operations.Sometimes, threats and intimidation against activists come from community members who have been promised economic benefit from the proposed project or are politically allied with the government or traditional authority."Local communities often do not benefit from mining activities, says the report. "Although South African law requires the development of social and labour plans (SLPs) that establish binding commitments by mining companies to benefit communities and mine workers, CALS has documented significant flaws in the development and implementation of SLPs."Despite the environmental and social costs of mining, the government is not adequately enforcing relevant environmental standards and mining regulations throughout South Africa. The SAHRC has found that the Department of Mineral Resources (DMR) often fails to hold mining companies accountable, "imposing few or no consequences for unlawful activities and therefore shifting the costs of pollution to local communities."Compliance with regulatory obligations, as well as monitoring and enforcement of such responsibilities, remains a crucial concern in the context of mining activities," says the SAHRC, noting how the DMR and other governmental agencies often do not respond to complaints filed against mines by community members.The report's authors describe how the lack of government action and oversight has also helped make the mining industry one of the least transparent industries in South Africa. Information that communities require to understand the impacts of mines and to hold mining companies accountable for harmful activities is often not publicly available. "Such information includes environmental authorisations, environmental management programs, waste management licences, atmospheric emission licences, mining rights, mining work programmes, social and labour plans, or compliance and enforcement information."The only way to access such information is through a request under South Africa’s access to information law, a procedure that the World Health Organisation has called 'seriously flawed' and which the DMR regularly flouts. In addition, mining companies and the government rarely consult meaningfully with communities during the mining approval process, resulting in uninformed and poor government and industry decisions that do not reflect community perspectives or have their support," says the report.The authors assert how the threats, attacks, and other forms of intimidation against community rights defenders and environmental groups have created an environment of fear "that prevents mining opponents from exercising their rights to freedom of opinion, expression, association, and peaceful assembly, and undermines their ability to defend themselves from the threats of mining".In its November 2018 review of South Africa’s compliance with the International Covenant on Economic, Social and Cultural Rights, the UN Committee on Economic, Social and Cultural Rights expressed concern about “reports of human rights defenders, particularly those working to promote and defend the rights under the Covenant in the mining and environmental sectors, being threatened and harassed". It recommended that South Africa provide a safe and favourable environment for the work of human rights defenders to promote and protect economic, social, and cultural rights, including by "ensuring that all reported cases of intimidation, harassment, and violence against human rights defenders are promptly and thoroughly investigated and the perpetrators are brought to justice". Mining activist Mariette Liefferink, who made submissions to the UN committee, tells how it has become increasingly difficult to work as an environmental rights defender in South Africa.   "There is an overwhelming body of evidence of intimidation, whether it is by means of frontal attacks or more insidious attacks on activists."International and South African law requires South Africa to guarantee the rights of all people to life, security, freedoms of opinion, expression, association, and peaceful assembly, and the rights to health and a healthy environment, say the authors."The attacks, threats, and obstacles to peaceful protest described in this report prevent many community activists in South Africa from exercising these rights to oppose or raise concerns about mines, in violation of South Africa’s obligations."
