Data Qualifiers and their meanings used throughout the Tier II Checklist
Estimated High (results are likely reported higher than the true value)
Estimated Low (results are likely reported lower than the true value)
Tentatively Identified, Quantitation Estimated
Note: The criteria used in the Tier II Data Validation checklist are derived mostly from SW-846 methods and U.S. EPA’s National
Functional Guidelines (NFGs). Criteria from methods are considered preferable as they are specific to that procedure. Where the
method is silent, criteria from the NFGs, or other sources when necessary, are adopted. For flashpoint (which uses ASTM methods
dictated by the rules), ASTM method criteria are used.
The Tier II methodology and terminology builds on that established in the Tier I checklist and its associated data validation manual.
There is no Tier II manual, only the checklist and completed example checklists. Additional information is also available by referring to
the specific methods.
