Hi Clive,
This approach is not quite what part 2a guidance says:
“Section 1: Objectives of the Part 2A regime 1.1 This Guidance should
be read and applied with Part 2A and the following points in mind. 1.2
England has a considerable legacy of historical land contamination
involving a very wide range of substances.
On all land there are
background levels of substances, including substances that are
naturally present as a result of our varied and complex geology and
substances resulting from diffuse human pollution.
On some land there
are greater concentrations of contaminants, often associated with
industrial use and waste disposal. In a minority of cases there may be
sufficient risk to health or the environment for such land to be
considered contaminated land.”

"Now "background" is clearly
defined in statute as the levels found in naturally occurring,
undisturbed ground."
It would be difficult finding any undisturbed
ground in the UK and then add in the effects of atmospheric deposition
from anthropogenic sources and there is no part of the UK that can be
thought of as undisturbed
