Contaminated land consultancy across diverse sectors

What is contaminated land?

'Contaminated land' is a wide-ranging term to describe the impact to soil and water from historical human activity. Land contamination is caused by a variety of practices, including industrial use, disposal of waste materials (licenced and unlicensed) and the importation of material to raise ground levels. In some cases, contamination of soils can occur due to naturally occurring compounds, typically metals.

In some cases – where there is a possibility that harm could be caused to certain water bodies, human health and ecology – land impacted by contamination can be determined as 'contaminated land'. This has a specific legal definition set out in Part IIA of the Environmental Protection Act.

The Environment Agency's land contamination risk management (LCRM) sets out the guiding principles and processes for the assessment and remediation of land contamination. The document is designed to ensure all environmental assessments are undertaken in accordance with government policies and/or legislation within the UK.

What does a land contamination assessment cover?

The environmental assessment is designed to analyse and address risks to:

  • Human health
  • Property (existing or proposed) including buildings, crops, livestock, pets, woodland and service lines and pipes
  • Adjoining land
  • Groundwaters and surface waters
  • Ecological systems
  • Archaeological sites and ancient monuments

Why might you need contaminated land consultancy?

Contaminated land can present numerous commercial, technical and legal challenges. These all generate uncertainty, costs and delays when land is being bought, sold or redeveloped. We know that your first priority is to protect your project's environment. We also appreciate the commercial aspect, and that your business can ill afford the potential financial, legal, and reputational damage that such obstacles can cause.

We strongly believe that the key to managing land contamination – and the successful completion of any development project – comes from straightforward, concise and timely advice which quantifies risks and delivers value.

Land quality management case studies

Emergency spill response to 21,000 litres of leaked fuel

The project: After an attempted theft of 25,000 litres of diesel at a distribution depot, much of the fuel was escaping underground and heading for a watercourse.

Our solution: Containment of the diesel in the first instance, followed by daily monitoring. Removal of the damaged tank and a comprehensive investigation over several weeks to check for any signs of land contamination.

The numbers: Around 130 birds rescued, with no other aquatic life impacted. Zero fines for our client, who only had to close three loading bays on a temporary basis.

Pollution prevention at a water utilities company

The project: An undetected spill of 50,000 litres of diesel after a contractor pierced a fuel line.

Our solution: Urgent clean-up, a comprehensive ground investigation and a long-term strategy. A negative gradient to guide the fuel away from waterways, plus a pump and treat system to separate oil from contaminated water.

The numbers: 30,000 litres of fuel recovered, while our client avoided a potential fine of £8 million due to our fast and effective response.
