Contaminated land in Bradford: what you need to know
Bradford’s industrial past has left a legacy of land contamination in certain areas. The City of Bradford Metropolitan District Council (commonly referred to as Bradford Council) is dedicated to managing these sites to ensure public health and environmental safety, while also promoting sustainable development.
This article looks at the legacy of contamination in the West Yorkshire city of Bradford, the council’s approach to reusing sites and what you need to do if you aim to develop a contaminated site.
Bradford’s industrial legacy and contamination issues
The city’s former textile manufacturing, dyeing, and engineering works have left behind contaminants including heavy metals, hydrocarbons, and asbestos. While such brownfield (previously developed) sites are earmarked for regeneration, their history means that careful ground investigations and management are required.
What are the risks from developing contaminated land?
New pathways may be opened for pollutants to spread and affect people’s health, controlled watercourses and ecosystems. The following three elements must be present for a risk to arise and without all three, the threat is minimal.
- A source of contamination.
- A pathway for pollution to reach receptors.
- A receptor such as people or the environment.
The legal framework
Part 2A of the Environmental Protection Act 1990 defines contaminated land as any site where substances in or under the ground present significant risks to health, property, or the environment. Key principles include:
- Taking a risk-based approach: assessing the likelihood of harm to people, water sources and the environment.
- The `Polluter Pays’ approach: remediating sites is the responsibility of the polluter if they can be identified.
- Remediation through development: contaminated land is assessed and cleaned up as part of future development.
Local authorities are required to identify and remediate land where contamination poses significant risks to health or the environment. The National Planning Policy Framework (NPPF) also emphasises the importance of remediating contaminated land. Paragraph 197 states that responsibility for the safe development of contaminated land rests with the developer, landowner, or both.
Bradford Council’s approach to contaminated land
Bradford Council employs a comprehensive strategy to manage contaminated land:
- Inspection and identification: the council conducts systematic inspections to identify potentially contaminated sites, prioritising those posing the highest risk to public health and the environment.
- Contaminated Land Register: a public register is maintained, documenting sites designated as contaminated under the Environmental Protection Act. This ensures transparency and public awareness of contaminated sites.
- Guidance for developers: the council provides detailed guidance for developers planning to build on land that may be contaminated, ensuring safe and suitable development practices across this West Yorkshire city.
Promoting brownfield redevelopment
Bradford Council is committed to the redevelopment of brownfield sites, aiming to reduce pressure on greenfield areas and promote sustainable urban growth. Cleaning up contaminated areas also reduces pollution risks and improves local ecosystems.
The council maintains a Brownfield Land Register, identifying sites suitable for residential development. Notable projects, such as the regeneration of the former Manningham Mills site, demonstrate its policy of transforming former industrial lands into viable spaces.
The Contaminated Land Risk Assessment
It’s important to firstly contact the council’s planning department for a Pre-Application Consultation to discuss potential contamination issues and the reports that will be required.
When dealing with potentially polluted land, it’s likely that a contaminated land risk assessment will be required prior to planning consent being granted. If the assessment confirms that contamination is present, it will explain the remediation measures necessary to enable the scheme to go ahead.
Geo-environmental consultants can conduct a Contaminated Land Risk Assessment according to the Environment Agency’s Land Contamination Risk Management guidelines. The assessment involves:
- Phase 1. Desk studies: researching historical maps, industrial records and environmental records to identify existing use and former uses that may have caused contamination.
- Phase 2. Contaminated land investigation: ground investigations will take place on site. Samples of soil and groundwater will be taken and analysed to check for contaminants. Vapour extraction may be required and landfill gas surveys in some cases. The investigations may involve digging trial pits to monitor ground conditions. A conceptual site model may be used to help with the assessment.
- Risk assessments: consultants will evaluate the potential risks to human health, water sources, and ecosystems.
- Remediation planning: if necessary, consultants will devise a remediation strategy. Measures might involve cleaning contaminated soil either on-site or off-site, groundwater remediation or capping areas of a site to prevent exposure of contamination.
- Validation and reporting: consultants will monitor remediation work to ensure that regulatory standards are met, and submit reports to the relevant local authority.
Site assessments give plans their best chance of success
By collaborating with developers and consultants, Bradford Council facilitates the transformation of historically contaminated sites into valuable assets.
Following contaminated land investigation and risk assessment, geo-environmental consultants can recommend the best steps to take to enable development projects to proceed. Adopting this phased approach will comply with regulations set by the Environment Agency and legislation.
