With nowhere else to live, many seek refuge in the radiation wastelands in Gauteng, unaware of the deadly dangers the abandoned mining areas present.

The broken glass from a window pane cracks underfoot, a jarring noise amid the drone of mining equipment in the distance. It is one of the few reminders of a time when this upstairs room was the kitchen of the old Randfontein Club.
Faded photographs in the town museum show people sunbathing and swimming in the lake in the 1980s. There were bars, a jetty and a miniature putting course. Now only the foundations remain after it was closed because of the increasing concentration of uranium in Robinson Lake.
In the past it was a place for the residents of Randfontein – 50km west of Johannesburg – to relax on the weekend and forget their jobs in the mining industry. But in the late 1990s the underground mines started closing because the falling price of gold and uranium made them unprofitable. The mines were abandoned and the water levels inside started rising. Acid mine drainage began seeping into the dam, increasing the level of uranium to levels 220 times higher than the safe limit. The resort closed.
Deep into winter a chill breeze blows across the lake, creating ripples in the clear water. The surface is a stark blue reflection of the sky, with the bottom tainted red from the heavy metals in the water. No alga grow here, no fish swim, no underwater life ripples the surface.

The periphery of the lake is a wide ring of cracked yellow earth. The soil beyond is brown. There are 20m-high blue gum trees. There are yellow signs with “Radiation area – Supervised area” wired to the fence around the area and nailed to the trees.

Gold seam

The Witwatersrand gold seam runs for about 100km, from Randfontein in the west of Johannesburg to Springs in the east. A century of mining drove a mining boom, thanks to this being the world’s largest concentration of the precious metal.
Mine shafts up to 3km deep were sunk. The waste was dumped above ground in over 400 mine dumps or tailings dams that now dot the province. These contain a mixture of heavy metals, and an estimated 600 000 tonnes of uranium.
The Cancer Association of South Africa (Cansa) says this is the only place in the world where large numbers of people live next to dumps full of uranium.

It says up to 400 000 people in the Witwatersrand are exposed to low levels of radiation as a result, and tests Cansa did on the teeth of residents in Carletonville found uranium levels 100 times higher than normal levels. It says no research has been done in Gauteng about long-term exposure to mine dumps.
Managers of one of the Witwatersrand mines lived 300m from Robinson Lake. Their large red-brick homes were abandoned when operations ceased in the late 1990s, and have been occupied by squatters.
Abandoned mines
The tarred streets, laid out in a grid, are crumbling and overgrown. A worn football emits a hollow thump each time it is kicked by a handful of children playing in the street. Next to them five young men are sitting with their backs to a wall, trying to absorb some of the weak midday sun.
Two empty cartons of Chibuku sorghum beer have been discarded. There are three unopened ones in a plastic bag. A tall and athletic-looking Ronald Chauke opens one of these, and hands it round. “What does this radiation mean?” he asks, in response to my asking whether they are experiencing any health problems.
I recommend he goes to the clinic and ask for information there, but it is a R22 round trip by taxi to Krugersdorp and people here are lucky if they find work for three days in a week. With the mines gone the only work is as domestic workers.
The men stand at the main intersection coming into Randfontein, waiting to be picked up as day labourers. He does not look at me while I explain that kidney problems are almost guaranteed, and cancer, typically thyroid, is likely.
The National Nuclear Regulator has found uranium concentrations of 16mg a litre in Robinson Lake. Water affairs says a maximum concentration of 0.07mg is safe to drink. In 2002 it was declared a radioactive site thanks to the levels of uranium – one of 50 in the Witwatersrand. The regulator fences these off because people cannot be exposed to them for prolonged time. When people do live in dangerous places, it must move them. But the fences around Robinson Lake keep being stolen for scrap.


South Africa has not done much of its own research, and relies in part on work carried out in eastern Germany, where uranium was mined during the Cold War. Here, old mines are fenced off and exclusion zones are established to ensure no one lives there. Naturally occurring uranium remains radioactive for billions of years, and these areas cannot be rehabilitated.
The National Nuclear Regulator had not responded to requests for comment by the time of going to print.

Chauke does not drink or use the water from Robinson Lake for washing. He does not know what the radiation signs mean, but the lake scares him anyway.
“We know we cannot go near there. The lake is not normal.” Sitting back in his plastic chair he points at a mine dump 3km away. “That is our real problem. When the dust blows you cannot see the other side of the road. It covers everything.” He says it makes him and others cough.
“How can we know what is happening [inside our bodies] if we do not go to the doctor?”

‘How can you know?’

Pride Ngwenya has lived next to Robinson for 15 years, a few houses from Chauke. “We are told nothing so how can you know what is happening inside you?” Wearing a heavy black coat against the cold, he says “the [radiation] signs mean nothing if they do not tell you”.
“Obviously that lake and the mines are making us sick. But because nobody gives us the information on what is happening. You say it will make our children have problems, so what can we do because this is where we live?”
Uranium and other heavy metals are dispersed through water and wind. With Johannesburg being a watershed, rivers start here and flow east and west towards the Indian and Atlantic oceans.
Research by the nuclear regulator says radiation seeps into these rivers from tailings dams and is carried far downstream. The town of Potchefstroom is down-river from Randfontein, and is home to Professor Frank Winde’s laboratory. A lecturer in geography and environmental studies at North-West University, he says there are more than 600 000 tonnes of uranium sitting above the soil in Gauteng.
Uranium levels inside kettles he tested in the town were 20 times higher than levels in towns with water that was not affected by mining. The South African levels for uranium in water are four times the level recommended by the World Health Organisation (WHO), he says. Untreated water that he tested upstream had levels 4 000 times higher than this limit.

Isolated tests

Although isolated tests have been conducted, there has never been a comprehensive study of the air and water pollution from mine dumps.
The nuclear regulator has found uranium levels in Lancaster Dam outside Potchefstroom were 1.9mg a litre, and those at the nearby Hippo Pond were 2.1mg. A brickyard next to the dam uses the sand here to create building material. The WHO says 0.015mg a litre is the maximum.
Very little research has been done into airborne pollution – uranium in the dust is so fine that it can be blown far afield. A 2002 study by the government’s Council for Geoscience said: “Mining has resulted in the dispersal of radioactive material into the environment via windblown dust, waterborne sediment and the sorption and precipitation of radioactivity from water into sediment bodies.”

It also mentions the problem of no research on air pollution. “The lack of information has been identified as a serious information gap” and there was a need for a “comprehensive, credible monitoring programme”. 

David Hamman, a researcher at North-West University, found traces of uranium in the kidneys of cattle living around the Wonderfonteinspruit.

Heavy metal vegetation

This river starts a few kilometres from where Chauke, in Randfontein, is sitting. Their kidneys had uranium levels 4 350 times higher than cattle living elsewhere. This was because of accumulation of heavy metals in the grass they were eating, thanks to dust and water, he found.
The South African Nuclear Energy Corporation released research in 2008 on vegetation around the Gerhard Minnebron wetlands near Potchefstroom. This found that levels of radioactive substances in plants such as oats and onions were three times higher than those considered safe for consumption. Speaking last year, former minerals minister Susan Shabangu said radiation levels were “not at a level that poses a threat to communities”.
In Krugersdorp, there is a community living on top of an old mine. The soil in the Tudor Shaft informal settlement was tested in 2010 by the Federation for a Sustainable Environment, an NGO, and found to have uranium levels of eight millisievert – the legal limit is one millisievert.
The residents and tailings dam were meant to be moved in 2010, but the federation opposed this, ¬saying that disturbing the earth would throw uranium into the air. They requested that research be done before work went ahead. In their court application around the same time they cited the lack of research.

Where the technology was not there in the past to extract them, companies are now re-mining the dams, thanks to the higher prices of gold and other heavy metals. This will see the dumps disappear. High-pressure water blasts the dams apart, and the sludge is carried away by pipes to processing plants. At present, there is research into the effect of disturbing the heavy metals, and the toll on nearby communities.

Remediation costs

There are 6 000 abandoned mines in South Africa, and the auditor general said in 2009 that it will cost at least R30-billion to remediate these. The legislation around mines is based on the principle of “polluter pays” but until the 1980s mines did not have to bear the cost of remediating the areas they had operated in.
Now, the mines are fully responsible. But the mines, through the Chamber of Mines, argue that current companies cannot be held liable for the negligence of companies that have closed. Environmental groups have opposed this and said that when a company is transferred (all mines and their dumps are owned by someone) its assets and liabilities are carried through to the next owner.
The Gauteng part of this strategy – “Regional Mine Closure” – says the worst affected population when it comes to exposure to possible radiation are “informal settlement dwellers” living next to affected rivers.
These are people who are likely to be more at risk of illness thanks to their “poor nutritional status related to poverty and the prevalence of HIV and Aids”, it said.

What does uranium do?
When uranium is ingested it is deposited in the kidneys, lungs, brain and bone marrow. The alpha particles – which contain massive doses of energy – sit in these parts and damage the tissue around them. Because it is an endocrine disrupter, it increases the risk of fertility problems and reproductive cancer. Large doses are fatal, but the constant exposure to low levels has intergenerational effects that are still not fully understood.
Mining’s inevitable legacy
Robinson Lake is across a gravel road from the treatment works for the West Rand basin. When the underground mines in the area shut down, they stopped pumping water from their shafts. These filled up and the water mixed with heavy metals underground. In the late 2000s this water started spilling out of abandoned shafts and into local rivers and wetlands. The water affairs department said it needed a billion rand to build treatment works, which involved extending a plant already run by the mines. This is now operating and has stopped the decant into this basin.
The central and eastern basins – Gauteng has three major water basins – are filling up but those treatment works are also nearing operation. They will have to operate forever, with an annual cost estimated by water affairs of around R300-million, to ensure that untreated water does not seep into water sources.


Notification of the Withdrawal of the Application of an Amendment of the Environmental Authorisation and Environmental Management Programme for the Sweet Sensation Sand Mining Operation in Free State

The concerted efforts and submissions to the Department of Mineral Resources and Energy (DMRE), the Applicant and its appointed Environmental Assessment Practitioner (EAP) by the Protect Vaal Eden Committee, Vaal Eden community, and the Federation for a Sustainable Environment have resulted in the withdrawal of the application of an amendment of the environmental authorisation and environmental management programme for the Sweet Sensation Sand Mining operation adjacent to the Vaal River.  The EAP was notified by the DMRE that further specialist studies would be required to determine the impact the application for a screening plant and process would have on the environment and that a Regulation 31 amendment process, which involves a public participation process, must be undertaken.  The FSE welcomes the DMRE’s notification.

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."
