Defra have published a new Contaminated Land Advise Note that seeks to clarify the role of soil guideline values (SGV's) in the determination of contaminated 
land. It seeks to ensure the use of detailed quantitative risk assessment by Local Authorities for determining land as Contaminated Land under Part IIA of the 
Environmental Protection Act 1995, rather than relying upon the excedance of an SGV.
