Land contamination can give rise to volatile contaminants which can pose a risk of harm to human health by asphyxiation or illness if inhaled. Vapours and gases such as methane may also pose a risk of fire or explosion.

Ongoing Update of Ground Gas Handbook - Ground Gas Information Sheets:

Land contamination can pose risks to buildings in a number of ways. Volatile contaminants and gases can accumulate and cause explosion or fire. Foundations and buried services can be damaged by corrosive substances and contaminants such as steel slags can create unstable ground conditions through expansion causing structural damage.

Land contamination can affect the health of people living, working, visiting or otherwise present on a site. The risk assessment process is used to establish whether there is an unacceptable risk to humans.

Contaminated Land Reports (CLR) - All withdrawn

A number of regulatory regimes now require an ecological risk assessment (ERA) to be carried out. All these regimes are concerned, in one way or another, with assessing the risk of significant harm to an organism, an animal or a whole ecosystem. To ensure consistency in ERA, Defra and the EA have developed an ERA framework for use in land quality assessments.

ERA framework

The framework offers a series of tiered activities, decisions and actions that provide a practical match between available resources and the severity of a land contamination problem. It allows decisions to be made rationally, consistently and transparently and forms the basis for discussions between the relevant parties (these may include: site owners, regulatory authorities and the local community).

Land contamination can affect groundwater, freshwater and coastal waters. Groundwater is particularly vulnerable to contamination as it underlies many sites and is difficult to clean up once polluted.
