Do treatability tests require elaborate QA/QC procedures?
No, the level of QA/QC conducted during EPA sampling and treatability testing is not necessary for facility treatability testing, but facilities should use a level of QA/QC that will ensure the quality of their data. Chapter 6 of the P2 Guidance Manual provides some direction on using QA/QC in treatability testing. The QA/QC procedures include preparation of a QA/QC plan and the collection of field duplicate, field blank, equipment blank, and trip blank samples.
