Cont… • Add reference to EPA surface sampling document. – The EPA document is excellent but did not necessarily  fit in the section indicated. Included reference in new  paragraph in section 8.4 on sampling practices . • The scenarios in 10.1 and 10.2 could use some  context – where/when is this particular  experimental set‐up needed, what is actually  being sampled? (is it a soil, or is it a sample  collection where the sample (eg aerosol, etc)  might be contaminated with soil?) – An introduction to this section was added to help with  context.

Cont… • A lot of information regarding the characteristics soil, but  not much on actual sample collection. These two  documents need to be studied and referenced: 1. Guidance on Obtaining Defensible Samples:  GOODSamples. 2015. AAFCO, Champaign,  IL. https://www.aafco.org/Publications/GOODSamples 2. Guidance on Obtaining Defensible Test Portions:  GOOD Test Portions. 2018 AAFCO, Champaign, IL.  https://www.aafco.org/Publications/GoodTestPortions – Text in section 8.4 was expanded to highlight the importance of  the comments. Guidance on considering the importance of  planning for experimental error was stressed but not fully  described. The links provided in the comments were provided  and encouraged.
