I'm a QC/QA manager from an environmental laboratory in Israel, we are analyzing soil for DRO and ORO contaminants.
Earlier this week we had an accreditation inspection, and the issue of ORO came up, since the method mentions specifically only GRO and DRO.
I know that this is an accepted modification of the method but the examiner asks for an "official" source.
Method, explanation about the modifications from the original 8015 or even an SOP from a governmental source would be great.
Additionally, so far I could not find any proficiency testing scheme for Oil Range Organics in soil.
Could someone point me in the right way?
Thanks in advance,
Mark
