The site-specific QAPP for passive badges specifies one laboratory blank, one LCS, and one LCS duplicate will be prepared per batch
of 20 samples. However, the laboratory was not specifying a maximum batch sample size. The laboratory was contacted and
directed to follow the QC sample frequencies specified in the site-specific QAPP. No qualifications were applied because the
LCS/LCSD met the QAPP acceptance criteria, and the LCS/LCSD data from previous datasets for this project have met the site-
specific QAPP acceptance criteria.

The site specific QAPP requires a laboratory reagent blank (LRB), laboratory media blank (LMB), laboratory control sample (LCS),
and LCS duplicate (LCSD) to be analyzed per batch of 20 samples. However, the laboratory analyzed 32 field samples in one sample
preparation batch consisting of one LRB, LMB, LCS, and LCSD, when the batch should have contained two LRBs, LMBs, LCSs, and
LCSDs. The laboratory was contacted about the deviation from the site specific QAPP, and moving forward the laboratory will
follow the quality control (QC) sample frequency requirements in the site specific QAPP. No qualifications were applied because
the QC samples met the QAPP acceptance criteria and the QC samples from previous datasets for this project have met the QAPP
acceptance criteria.

INTRODUCTION
This checklist summarizes the Stage 2A validation performed on the subject laboratory report, in accordance with the U.S. Environmental
Protection Agency (EPA) Guidance for Labeling Externally Validated Laboratory Analytical Data for Superfund Use (January 2009). Analytical data
were evaluated in general accordance with the Tetra Tech Quality Assurance Project Plan East Palestine Train Derailment Site East Palestine,
Columbiana County, Ohio, EPA Region 5, Revision 3 (April 2023), the Tetra Tech Quality Assurance Project Plan, Superfund Technical Assessment
and Response Team (START V), EPA Region 5, Revision 4 (August 2022), and the EPA National Functional Guidelines (NFG)for Organic Superfund
Methods Data Review (November 2020).
OVERALL EVALUATION
No rejection of results was required for this data package. The results may be used as qualified based on this validation effort.
Data completeness:
Within
Criteria
Exceedance/Notes
Y
The report was amended to correct the value for volume for sample EPD-ST-8H-WA-05-060823-2 from "23.35" to "23.52".
The results for the field blank were reported in units of micrograms (ng) while the other sample results were reported in units of
Hg, milligram per cubic meter (mg/m3), and parts per million (ppm) (volume) in the laboratory report and only ppm in the
electronic data deliverable (EDD) except for blanks which provided results in ng.

Data completeness (continued):
Within
Criteria
Exceedance/Notes
Y
The sample analysis time was reported as a default value of 12 AM or 00:00 hours for the LCSD in the analysis date field. The
analysis date was correct. The sample analysis time for the LCSD was not required for the EDD; therefore, this value was not
manually revised.
The laboratory report uses method reference "Rohm & Haas IH9805" (referenced to the AIHA certification as IHGC-P029) or "IHGC-
P029" interchangeably.
Sample preservation, receipt, and holding times:
Within
Criteria
Exceedance/Notes
Holding time limits were exceeded in the extraction of the samples. All sample results were non-detect, and therefore qualified as
non-detect with possible low bias (flagged UJ).

Overall Qualifications:
See results summary pages attached for changes to the laboratory qualifiers based upon this validation. The following is a list of qualifiers and
definitions that may be used for the validation of this data package:
J
The analyte was positively identified; the associated value is the approximate concentration of the analyte in the sample.
J+
The analyte was positively identified; the associated value is the approximate concentration of the analyte in the sample and may be
biased high.
J-
The analyte was positively identified; the associated value is the approximate concentration of the analyte in the sample and may be
biased low.
NJ
The analysis indicates the presence of an analyte that has been "tentatively identified" and the associated value is the approximate
concentration of the analyte in the sample.
R
The sample result is rejected as unusable due to serious deficiencies in one or more quality control criteria. The analyte may or may not
be present in the sample.
U
The analyte was analyzed for, but was not detected at or above the associated value (reporting limit).
UJ
The analyte was analyzed for, but was not detected at or above the associated value (reporting limit), which is considered approximate
due to deficiencies in one or more quality control criteria.
