Exposé of Monsanto Waste Practices
Former Monsanto employee Stephen Constance, who spent three years sealing toxic waste underground at the company’s Newport factory in the 1990s, told investigators that staff were provided with “cheap” protective equipment and were not informed about the nature of the material they were burying. Constance’s account emerged after the BBC Wales documentary *Buried* with Michael Sheen highlighted the legacy of toxic waste in Wales. He was among dozens of individuals who contacted the broadcaster following the programme’s investigation into the dumping of polychlorinated biphenyls (PCBs).
Historical Context of PCB Use and Bans
The United Kingdom banned PCBs in the 1970s, and the chemicals have since been prohibited in 151 countries.
Scope of Contaminated Sites in the UK
Dr David Megson, the scientist featured in the documentary, estimated that the 14 sites identified in the programme represent only a fraction of the problem, with roughly 20,000 “high-concern” sites across the United Kingdom. These figures reflect an attributed claim from Megson based on his assessment of available data.
Official Responses and Industry Silence
Eastman Chemical Company, which inherited Monsanto’s legacy production responsibilities in the UK, declined to comment when approached for a statement. No formal response from the company has been recorded in the sources.
Implications for Public Health and Regulation
The revelations underscore ongoing concerns about the adequacy of protective measures for workers handling hazardous waste and the transparency of waste-management practices. Environmental health advocates argue that the large number of potentially contaminated sites warrants renewed governmental investigation and stricter oversight to prevent further exposure to PCB residues.
