BBC Investigation Reveals Lack of Testing at Potentially Contaminated Sites
A BBC investigation has uncovered that thousands of potentially toxic sites across Britain remain unchecked due to a lack of government funding. These sites, believed to be contaminated with hazardous chemicals such as lead and arsenic, could pose significant health risks to nearby communities.
According to data collected through a Freedom of Information (FOI) request, nine out of ten high-risk areas have not been inspected by councils, despite legal requirements under the Environmental Protection Act. Out of 13,093 identified high-risk sites, only 1,465 have been physically tested, raising concerns about public safety.
🔹 Councils Struggle with Lack of Resources
The UK government states that local authorities are responsible for inspecting and managing potentially contaminated sites. However, many councils argue that they lack the financial resources to conduct proper investigations.
A total of 73 out of 122 unitary authorities in England, Scotland, and Wales responded to the BBC’s FOI request, revealing that more than 430,000 sites were flagged as potentially contaminated in the early 2000s. Of these, 13,093 were classified as high risk, yet over 11,000 remain untested.
In Wales, half of the 22 councils either declined to provide figures or claimed they did not have sufficient data. Among those that responded, 698 high-risk sites were identified, yet 586 remain unchecked.
🔹 The Silent Threat Beneath Our Feet
Dr. Ian Mudway, an expert on pollution and human health, warns that the government fails to account for the long-term health impacts of toxic contamination.
“We don’t conduct full economic evaluations of environmental hazards, including their effects on public health. That feels almost criminal,” said Dr. Mudway.
“We haven’t even begun to scratch the surface.”
Toxic sites include areas previously used as:
✔ Factories & Power Stations
✔ Railways & Landfills
✔ Petrol Stations & Dry Cleaners
For homes built after 2000, contamination risks should have been addressed under updated planning laws. However, for properties constructed before 2000, the risks remain unclear.
🔹 The Case of Cwmystwyth: A Toxic Legacy
One of the worst-affected areas is Cwmystwyth in mid-Wales, home to over 400 abandoned metal mines. The Ystwyth, Rheidol, and Clarach rivers in the region are among the most polluted in the UK, with zinc, cadmium, and lead contamination traced back to historical mining activities.
Local resident Robin Morris, who installed a filtration system for his drinking water, was alarmed when soil testing in his garden revealed high lead levels—well above the safe limit for gardening.
“It causes alarm bells to ring,” he told BBC Wales Investigates.
“We should have stopped growing vegetables long ago.”
Past incidents now make more sense—including cases of lame ducks and chickens on his property, which veterinarians suspect was due to lead poisoning.
🔹 Lead Poisoning: A Persistent Danger
According to Dr. Ian Mudway, there is no safe level of lead exposure. Long-term exposure can cause:
- Developmental issues in children
- Kidney damage
- Cardiovascular diseases in adults
“Nothing is more of a ‘forever chemical’ than lead,” said Dr. Mudway.
“It is a clear and present danger to the population, contributing to an estimated 500,000 to 1 million premature deaths globally each year.”
🔹 The Chiswell Family: A Case of Lead Poisoning
Manon Chiswell, now 20 years old, was wrongly diagnosed with autism as a toddler after she suddenly stopped talking.
“I couldn’t speak. My teachers had to use a traffic light system and yes/no cards to help me communicate,” she recalled.
A blood test later revealed dangerously high levels of lead, proving she had been poisoned—likely from contaminated soil near her family’s Cardiff home, which was close to an old industrial site.
Her father, Huw Chiswell, recalled how Manon, as a toddler, had a habit of eating soil in their garden.
“Once she stopped, she got better,” he said.
The UK government report also flagged other dangerous substances, such as:
- Arsenic
- Nickel & Chromium
- Polycyclic Aromatic Hydrocarbons (PAHs)
🔹 Zane’s Law: A Push for Transparency
Environmental campaigners are calling for Zane’s Law, named after Zane Gbangbola, a seven-year-old boy who died from toxic gas exposure after the River Thames flooded his home in 2014.
His parents believe the deadly fumes came from a nearby landfill site.
The proposed law aims to:
✅ Force councils to maintain a public register of contaminated sites
✅ Increase government funding for land inspections
✅ Hold polluting industries accountable
“You have to know contamination exists before you can protect yourself,” said Zane’s father, Kye Gbangbola, who was left paralyzed due to the poisoning.
🔹 Former Minister Calls for Urgent Action
Lord John Selwyn Gummer, the former UK Environment Secretary (1993-1997) who introduced strict land contamination regulations 25 years ago, criticized the lack of government funding to enforce these rules.
“Local authorities simply don’t have the resources to do this job,” he stated.
As toxic threats continue to go unchecked, experts and campaigners warn that the long-term cost of inaction—both in health and financial terms—could be far greater than addressing the issue now.
