Contaminated land contains harmful chemicals in sufficient quantities so as to present a risk or potential risk to human health or the environment. The law dictates when land is legally defined as being 'contaminated' and tries to ensure that such land does not present a significant risk to health or the environment.
The Government's long-term aim is to work towards a future where all the potentially contaminated land in England and Wales has been identified, assessed and made safe. The scale of the task means this is likely to take many years to achieve.
To assist this study, BSI has published BS 10175 Investigation of potentially contaminated sites - Code of practice. This British Standard provides recommendations and guidance on the investigation of land potentially affected by contamination or naturally elevated concentrations of potentially harmful substances in order to determine or manage any risks.
BS 10175 allows users to:
- Set the objectives of an investigation
- Develop a strategy for the investigation
- Identify risks arising from the presence of contamination
- Design the different phases of the investigation
- Carry out sampling, field testing and laboratory analysis
- Enable risk assessment of a potentially contaminated site.
It is intended for use by those with an understanding of the risk‑based approach to the assessment of sites as described in the Model Procedures for the Management of Land Contamination (CLR 11) .
The relevant recommendations and guidance within this standard are intended to ensure that the objectives of an investigation are achieved and that appropriate data for the risk assessment are obtained. However, it is not feasible to provide detailed guidance for every possible investigation scenario.
The results of the investigation ought to delineate all known aspects of the site that could impinge upon or affect source-pathway-receptor scenarios defined within the conceptual model.
This is an amendment to BS 10175:2011 due to the publication of the new BS 8576 and planned revision of BS 5930 Code of practice for site investigations.
