Contaminated land assessment involves a staged process of investigation and risk assessment undertaken by suitably certified, qualified and experienced consultants.
The contaminated site assessment process often commences with a consideration of whether land is potentially contaminated. Potentially contaminated land means land which could have been contaminated by a potentially contaminating activity (PCA) which is currently occurring or was historically hosted on the land or adjacent land. The potential for contamination to create a risk is dependent on the nature of the chemical substances used in the activity, the reactions and by-products from such substances, the extent and concentrations present on the land and on the nature of the proposed use and development.
EPA publishes datasets which may assist in the development of site history. This is often the first step in determining likely sources of contamination on a site.
Should your site host or have formerly hosted underground petroleum storage systems (UPSS) you can find further information on the Underground Fuel Tanks webpage.
