Developing contaminated land in Glasgow? Help with planning applications
If you’re planning to buy, build, or redevelop land in Glasgow, it’s essential to understand the potential risks of contaminated land. Like many former industrial cities in the UK, Glasgow has a manufacturing history; some of that legacy lies hidden in the form of soil and groundwater contamination. For developers, investors, and landowners, being aware of these issues – and how to deal with them – is a crucial part of responsible development.
This article will help you understand what contaminated land is, how it affects development, Glasgow Council’s contaminated land regime, and the steps to take if you’re developing a potentially contaminated site.
Contaminated land explained
Contaminated land refers to any site where substances in the ground pose a risk of significant harm to human health, the environment, buildings, or controlled waters. These contaminants can include heavy metals, hydrocarbons like petrol or oil, asbestos, solvents, radioactive contamination or gases. Often, this pollution is left behind from historic industries, agricultural activities or poorly managed waste disposal.
The presence of contaminants doesn’t necessarily mean a site can’t be developed, but it does mean it must be properly assessed for potential risks: if necessary, remediation work must be carried out to ensure it’s safe for its intended use with no risk of future land contamination for the local community.
Scotland’s contaminated land regime
The Scottish Government has issued statutory guidance outlining the core principles for identifying and dealing with contaminated land. Under this framework, local authorities (such as South Lanarkshire Council, bordering the south-east of Glasgow City Council area) act as the primary regulator, responsible for investigating land contamination and ensuring appropriate remedial works. The Scottish Environment Protection Agency also plays a key role; it will regulate activities particularly in cases involving special sites or complex contamination issues. Scottish ministers also aim to bring Scottish vacant and derelict land back into productive use. The Scottish executive aims to promote economic activity, while ensuring that development does not pose risks of significant harm to human health or the environment.
Why is contaminated land a problem in Glasgow?
For more than a century, Glasgow was a powerhouse of shipbuilding, steel, heavy engineering, and chemical manufacturing. While these industries fuelled the city’s economy, they also left a legacy of pollution, particularly in areas like the River Clyde corridor, former dockyards, industrial estates, and waste tipping sites. The Scottish government has a comprehensive contaminated land policy based around pollution prevention, protection of protected species and the removal of any unacceptable risk of environmental impacts.
The main issues posed by contaminated land in Glasgow today include:
- Health risks for site users, workers, and residents
- Ground gas hazards like methane from decomposing materials
- Polluted groundwater affecting water quality
- Radioactive substances
- Damage to buildings from chemical corrosion or subsidence
- Increased costs and delays during development if issues are uncovered late
- Planning restrictions from the council until contamination risks are addressed
Glasgow City Council’s contaminated land policy
Glasgow City Council has a legal duty under the Part iia regime of the Environmental Protection Act 1990 to identify, inspect, and manage contaminated land. The council’s statutory guidance balances public safety, environmental protection and economic regeneration. It also maintains a public register of contaminated land sites.
Key priorities include:
- Protecting human health and environmental health
- Preserving the quality of groundwater, surface water and controlled waters
- Encouraging brownfield redevelopment rather than building on greenfield land
- Ensuring proposed development is suitable for its intended use
As the enforcing authority, the council requires developers to assess potential contamination risks on any site with a history of industrial use. Where necessary, remediation work must be carried out on land affected by contamination to meet safety standards before development proceeds.
Which historic industries left contamination in Glasgow?
Many of Glasgow’s former industries have left long-term contamination in the ground posing a risk of significant pollution. Contaminated land sites include:
- Shipbuilding and marine engineering along the Clyde
- Steel and ironworks
- Gasworks, which produced coal gas for lighting and heating
- Chemical works, including dye production, paint manufacturing, and tanneries
- Rail depots and sidings
- Petrol stations
- Inadequate waste disposal and landfill operations
- Agricultural activities and agricultural waste
Even residential and commercial developments built on reclaimed land may contain buried contaminants, construction rubble, or asbestos from demolished buildings. The risk of significant harm from such sites and industrial sites must be fully investigated to satisfy planning conditions and prevent future land contamination.
Is Glasgow Council encouraging brownfield development?
Glasgow City Council is committed to sustainable development and recognises the value of reusing brownfield land rather than expanding into undeveloped countryside. Revitalising former industrial areas not only supports housing and the economy, it also helps regenerate communities and protect green space.
However, to make this possible, the planning authority expects developers to demonstrate that sites have been properly assessed for contamination and made safe before use. Contaminated land is a material planning consideration and the planning system aims to ensure land is “suitable for use” without risking human health or the environment. Developers have certain responsibilities to prove that potential risks from their site are fully investigated, and to provide any additional information requested by the planning authority.
Steps to take if you want to develop a site in Glasgow
If you’re considering a development on potentially contaminated land, it’s important to engage a contaminated land consultant early in your project. They’ll help you understand your site’s history, its current state and identify any risks and environmental impacts from your development plans. They can also recommend the required remediation of contaminated land and guide you through the local planning authority regulatory process.
The detailed framework of the contaminated land assessment process typically includes:
- Preliminary Risk Assessment (Desk Studies)
This involves examining historical maps, aerial photos, and environmental records to determine whether the site could be contaminated based on past or current use. - Site Investigation (Intrusive Testing)
If the desktop study raises concerns, a physical investigation will follow. This includes investigations of the current state of soil, the water environment, and ground gas sampling to test for specific pollutants. Further reports may be needed such as protected species surveys or a derelict land survey. - Risk Assessment and Remediation Strategy
Land identified as containing contaminants at above acceptable levels will require a plan for the remediation of contamination. Site specific solutions might include soil removal, gas protection systems, or capping contaminated material to prevent future contamination. In some instances, an integrated pollution control solution may be recommended to enable the planned end use of the site. - Validation and Verification
Once remediation is complete, testing is repeated to confirm that the land meets safety standards and any unacceptable risk is dealt with. A validation report is submitted to the council as part of the planning process to prove that the remediation required has been satisfactorily carried out. Planning applications may be submitted into the planning system at this stage.
The Role of a Contaminated Land Consultant
A contaminated land consultant is a specialist who manages the environmental assessment and remediation process on potentially contaminated sites. They liaise with the local planning authority and design risk-based strategies to help you meet legal obligations imposed by the part iia regime and other legislation.
By identifying past uses and current use of a site they will assess any environmental impacts and manage contamination problems, reducing the risk of delays, unexpected costs, or a remediation notice being issued later on. For projects involving contaminated land in Glasgow, a consultant plays a key role in your team.
