April 2017 Groundwater Monitoring Sampling and Analysis Results Airport Fills
Dear Sir or Madam:
Attached are the results from the most recent semi-annual groundwater monitoring sampling
event conducted in April 2017 for the wells near the Area I, III and :IV structural fills at the
Asheville Regional Airport. The results from these sampling events -are included on the
GW59CCR forms per permit WQ0000020, dated September 2, 2015. As these structural fill
sampling events are not part of an NPDES permit, these forms were slightly modified and are
not signed.
.Area I groundwater;.monitoring wells and surface water samples were collected on April 21 &
24, 2017. Area III groundwater monitoring wells were sampled on April-20 & 21, 2017 and Area
IV groundwater monitoring wells were sampled on April 21 & 24, 2017.
Per our letter to Mr. Brett Laverty, NC DENR, dated March 2, 2105, DEP contacted the MSD
Industrial Waste Section and asked that they contact Mr. Laverty such that Mr. Laverty could
retrieve information directly from MSD regarding leachate quantity and quality.for.Area III and
Area IV leachate discharges. If this arrangement has proved unsuitable, please let Ms. Teresa
Williams know at 828-687-5240.
Sincerely,
Garry A.Whisnant

DEFINITIONS
DF-Dilution Factor,if reported,represents the factor applied to the reported data due to-dilution of the sample aliquot.
ND-Not Detected at or above adjusted reporting limit.
J-Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
MDL-Adjusted Method Detection Limit.
PQL-Practical Quantitation Limit.
RL-Reporting Limit.
S-Surrogate
1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270.The result for each analyte is
a combined concentration.
Consistent with EPA guidelines,unrounded data are displayed and have been used to calculate%recovery and RPD values.

Program Comments:
The following report has been revised to correct the sampling dates for MW7-A3 and the duplicate.
Data Flags &Calculations:
Any analytical tests or individual analytes within a test flagged with a Qualifier indicate a deviation from the method quality
system or quality control requirement. The qualifier description is found at the end of the Certificate of Analysis (sample results)
under the qualifiers heading. All results are reported on a dry weight basis unless otherwise noted. Subcontracted data
included on the Duke Certificate of Analysis is to be used as information only. Certified vendor results can be found in the
subcontracted lab final report. Duke Energy Analytical Laboratory subcontracts analyses to other vendor laboratories that have
been qualified by Duke Energy to perform these analyses except where noted.
Data Package:
This data package includes analytical results that are applicable only to the samples described in this narrative.An estimation of
the uncertainty of measurement for the results in the report is available upon request.This report shall not be reproduced, except
in full,without the written consent of the Analytical Laboratory. Please contact the Analytical laboratory with any questions.The
order of individual sections within this report is as follows:
Job Summary Report, Sample Identification, Technical Validation of Data Package,Analytical Laboratory Certificate of Analysis,
Analytical Laboratory QC Reports, Sub-contracted Laboratory Results, Customer Specific Data Sheets, Reports&
Documentation, Customer Database Entries, Test Case Narratives, Chain of Custody(COC)
Certification:
The Analytical Laboratory holds the following State Certifications : North Carolina (DENR) Certificate#248, South Carolina
(DHEC) Laboratory ID#99005. Contact the Analytical Laboratory for definitive information about the certification status of

QUALIFIERS
Project: J17030483
Pace Project No.: 92338010
DEFINITIONS
DF-Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot.
ND-Not Detected at or above adjusted reporting limit.
J-Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
MDL-Adjusted Method Detection Limit.
PQL-Practical Quantitation Limit.
RL-Reporting Limit.
S-Surrogate
1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270.The result for each analyte is
a combined concentration.
Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate%recovery and RPD values.
LCS(D)-Laboratory Control Sample(Duplicate)
MS(D)-Matrix Spike(Duplicate)
DUP-Sample Duplicate
RPD-Relative Percent Difference
NC-Not Calculable.
SG-Silica Gel-Clean-Up
U-Indicates the compound was analyzed for,but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.
A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis ofAcrolein and Acrylonitrile by EPA
Method 8260.
N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for
each analyte is a combined concentration.
Pace Analytical is TNI accredited.Contact your Pace PM for the current list of accredited analytes.
TNI-The NELAC Institute.
LABORATORIES
PASI-A Pace Analytical Services-Asheville
ANALYTE QUALIFIERS
D6 The precision between the sample and sample duplicate exceeded laboratory control limits.
M1 Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample(LCS)recovery.
M6 Matrix spike and Matrix spike duplicate recovery not evaluated against control limits due to sample dilution.
R1 RPD value was outside control limits.

Please contact the Program Manager(Anne Pridgeon)with any questions regarding this report.
Data Flags&Calculations:
Any analytical tests or individual analytes within a test flagged with a Qualifier indicate a deviation from the method quality
system or quality control requirement. The qualifier description is found at the end of the Certificate of Analysis (sample results)
under the qualifiers heading. All results are reported on a dry weight basis unless otherwise noted. Subcontracted data
included on the Duke Certificate of Analysis is to be used as information only. Certified vendor results can be found in the
subcontracted lab final report. Duke Energy Analytical Laboratory subcontracts analyses to other vendor laboratories that have
been qualified by Duke Energy to perform these analyses except where noted.
Data Package:
This data package includes analytical results that are applicable only to the samples described in this narrative.An estimation of
the uncertainty of measurement for the results in the report is available upon request.This report shall not be reproduced, except
in full,without the written consent of the Analytical Laboratory. Please contact the Analytical laboratory with any questions.The
