Notes:* - Flow measurement was taken at W.O. Huske Dam - USGSGauge Site No. 021055001. Flow at Old Outfall 002, Seep A, Seep B and Seep C locationswere measured using flumes.2. Flow at Seep D was measured using salt diultion.3. Flow at Willis Creek and Georgia Branch Creek were measuredusing flow velocity method.4. Results of estimated flow at these locations are provided inTable 5 and Table 7 with supplemental flow measurement dataincluded in Appendix B.5. The outline of Cape Fear River is approximate and is based onopen data from ArcGIS Online and North Carolina Department ofEnvironmental Quality Online GIS.

LABORATORY REPORTS

DATA REVIEW NARRATIVES AND
LABORATORY REPORTS

Data review narratives are included in this appendix. Due to file size limits, analytical laboratory
reports will be provided separately with the hard copy of the report.
All analytical data were reviewed using the Data Verification Module (DVM) within the LocusTM
Environmental Information Management (EIM) system, which is a commercial software program
used to manage data. Following the DVM process, a manual review of the data was conducted.
The DVM and the manual review results were combined in a data review narrative report for each
set of sample results, which were consistent with Stage 2b of the EPA Guidance for Labeling
Externally Validated Laboratory Analytical Data for Superfund Use (EPA-540-R-08-005 2009).
The narrative report summarizes which samples were qualified (if any), the specific reasons for
the qualification, and any potential bias in reported results. The data usability, in view of the
project’s data quality objectives (DQOs), was assessed and the data were entered into the EIM
system.
The data were evaluated by the DVM against the following data usability checks:
 Hold time criteria;
 Field and laboratory blank contamination;
 Completeness of QA/QC samples;
 MS/MSD recoveries and the relative percent differences (RPDs) between these spikes;
 Laboratory control sample/control sample duplicate recoveries and the RPD between these
spikes;
 Surrogate spike recoveries for organic analyses; and
 RPD between field duplicate sample pairs.

Data Review
The electronic data submitted for this project was reviewed via the Data Verification Module (DVM) process.
Overall the data is acceptable for use without qualification, except as noted below:
•Some table 3+ results in three water samples were qualified B and the reported results may bebiased high, or false positives, due to a comparable concentration found in the associatedequipment blank. Byproduct 5 and PFMOAA results in sample ID EXCESS RIVER WATER-
091719 were also impacted by an MS RPR outside criteria indicating estimated results but the Bqualifier supercedes the J qualifier.
•Several analytical results have been qualified J as estimated, and non-detect results qualified UJindicating an estimated reporting limit, due to a poor laboratory matrix spike; sample analysiswhich exceeded the laboratory preparation hold time; and poor field duplicate or lab replicate
precision. See the Data Verification Module (DVM) Narrative Report for which samples werequalified, the specific reasons for qualification, and potential bias in reported results.

Data Verification Module (DVM)
The DVM is an internal review process used by the ADQM group to assist with the determination of data usability. The electronic data deliverables received from the laboratory are loaded into the Locus EIM™ database and processed through a series of data quality checks, which are a combination of software (Locus EIM™ database Data Verification Module (DVM)) and manual reviewer evaluations. The data is evaluated against the following data usability checks:
• Field and laboratory blank contamination
• US EPA hold time criteria
• Missing Quality Control (QC) samples
• Matrix spike(MS)/matrix spike duplicate (MSD) recoveries and the relative percent differences
(RPDs) between these spikes
• Laboratory control sample(LCS)/control sample duplicate (LCSD) recoveries and the RPD
between these spikes
• Surrogate spike recoveries for organic analyses
• RPD between field duplicate sample pairs
• RPD between laboratory replicates for inorganic analyses
• Difference / percent difference between total and dissolved sample pairs. There are two qualifier fields in EIM: Lab Qualifier is the qualifier assigned by the lab and may not reflect the usability of the data. This qualifier may have many different meanings and can vary between labs and over time within the same lab. Please refer to the laboratory report for a description of the lab qualifiers. As they are lab descriptors they are not to be used when evaluating the data. Validation Qualifier is the 3rd party formal validation qualifier if this was performed. Otherwise this field contains the qualifier resulting from the ADQM DVM review process. This qualifier assesses the usability of the data and may not equal the lab qualifier. The DVM applies the following data
evaluation qualifiers to analysis results, as warranted: Qualifier Definition B Not detected substantially above the level reported in the laboratory or field blanks. R Unusable result. Analyte may or may not be present in the sample.
J Analyte present. Reported value may not be accurate or precise.
UJ Not detected. Reporting limit may not be accurate or precise.

The Validation Status Code field is set to “DVM” if the ADQM DVM process has been performed. If the DVM has not been run, the field will be blank.
If the DVM has been run (Validation Status Code equals “DVM”), use the Validation Qualifier.
