An inquiry into issues at Hafod Landfill Site near Wrexham has revealed a failure of accountability - where technical compliance takes precedence over people’s daily reality enduring years of odour nuisance, says the Senedd Petitions Committee.
The Committee found that while regular monitoring is being carried out at the landfill site near Johnstown, there is a clear gap between what scientific measurements deem acceptable and the lived experience of neighbours.
Prompted by a petition signed by 1,125 people, the Committee’s short inquiry heard how for nearly two decades, residents have reported distress caused by persistent odours, describing impacts on daily life and wellbeing. Families told how they are unable to open windows, enjoy gardens, or let children play outside. Some report that the odour worsens after rainfall, adding to fears about long-term exposure and quality of life.
While monitoring data suggests health risks are low, the Committee notes that nuisance levels remain unacceptable and trust between the community, regulators and the operator has broken down.
Chair of the Senedd Petitions Committee, Carolyn Thomas MS said:
“No community should have to endure conditions like those described to us. We deeply admire the perseverance of campaigners who have fought for change despite years of frustration. Their determination has ensured this issue could not be ignored.
“Welsh Ministers, Natural Resources Wales, and Wrexham Council must act on our recommendations to strengthen monitoring, improve communication, and rebuild trust with the community.
“People need to feel their voices are heard and their concerns taken seriously and Senedd Petitions are a vital way for people to raise issues that matter to them. While the Committee cannot direct the closure of the site, we have been able to put residents’ voices on the record, hold regulators and the operator to account, and shine a light on problems that have persisted for far too long.
“Since our inquiry started, efforts to resolve the odour issues have intensified. Senedd Members want to see that momentum maintained, with tangible improvements to the lives of people affected by landfill sites.”
The report makes 10 recommendations, including:
- Mandatory automated odour monitoring at landfill sites across Wales.
- Improved training for regulators conducting odour assessments.
- Clearer communication from local authorities on enforcement actions.
- Investigation into climate resilience and the link between rainfall and odour emissions.
The Committee urges Welsh Ministers and Natural Resources Wales to act on its findings and ensure robust measures remain in place.
