Study reveals 'potentially harmful' levels of metal in rivers and soil across Corby
Thirty volunteer scientists tested 52 water sites and 28 soil samples, with the Environment Agency now reviewing the results
A new report from Earthwatch Europe in collaboration with the Corby community has uncovered levels of metal pollution in the town's rivers and soils, which officials say could pose a risk to the environment and human health.
Testing was conducted by 30 citizen scientists across 52 freshwater sites and 28 soil samples.
The community-led initiative follows previous inquiries into historical contamination linked to the former British Steel works.
Analysis identified elevated levels of nickel and cadmium in water samples and cadmium and arsenic in soil samples, particularly near Deene Quarry and a slag heap in Weldon.
Earthwatch Europe's Independent Scientific Advisor, Dr Sasha Woods, stressed the importance of the findings, saying they highlight areas where further investigation and remedial action may be required to address metal pollution risks.
Sam Smithies from Artemis Analytical echoed the significance of the study, acknowledging the role of scientific analysis in understanding environmental impact.
Local MP Lee Barron has asked for the local council to publish a plan addressing the contamination risks identified in the report.
He said: “Once again our community have stepped up to take part in this mammoth exercise. My thanks go to Earthwatch, and the scientists who have helped to make this possible and the citizen scientists who volunteered their time.
“I understand the concerns of residents, and believe this report is an important step in their campaign. This report contains scientific data which gives decision makers an invaluable insight into what work needs to be done.
“Local authorities have a duty to inspect and identify sites where contamination is causing unacceptable risks and North Northamptonshire Council should immediately publish a plan to make these sites safe.”
An Environment Agency spokesperson said: "We welcome the work of citizen science volunteers in Corby, and the commitment residents are showing to protecting their local environment. "We are reviewing the latest Earthwatch report alongside our own evidence. Our monitoring to date does not indicate widespread or significant harm to the freshwater environment across the Corby area. We will continue to assess the evidence and take any further action needed."
The investigation forms part of Earthwatch Europe’s effort to engage communities in citizen science for evidence-based environmental action.
North Northamptonshire Council says it takes environmental concerns extremely seriously and is aware of the findings.
A spokesperson added; “We welcome the work undertaken and will now review the report in detail, alongside other relevant partners where appropriate.
“It is important that we fully assess the data and supporting information with a detailed technical review to determine whether any further investigation is required.
“Residents can be assured that any credible evidence of a risk to human health or the environment will be thoroughly considered and investigated through the appropriate regulatory processes.”
