Hello all
I was wondering if anyone favours using specific generic assessment screening
criteria for initial evaluation of reported TPH concentrations in soil. Most
assessments I have come across or been involved in make use of the TPH
CWG split analysis. However, I am trying to evaluate SI data generated by
someone else, and the TPH banding has been split as follows:
TPH by GC (>C6 - C10)
TPH by GC (>C10 - C20)
TPH by GC (>C20 - C40)
TPH by GC (>C6 - C40)
Can anyone shed any light on appropriate generic criteria which would be
appropriate to use?
Thanks in anticipation.
