I. INTRODUCTION:

This laboratory was inspected by a representative of the North Carolina Wastewater/Groundwater
Laboratory Certification (NC WW/GW LC) program to verify its compliance with the requirements
of 15A NCAC 2H .0800 for the analysis of environmental samples.

II. GENERAL COMMENTS:

Proficiency Testing (PT) samples for the 2016 proficiency testing calendar year have not yet been
analyzed. The laboratory is reminded that these results must be submitted to this office directly
from the vendor by September 30, 2016.

The laboratory submitted their Quality Assurance (QA) and/or Standard Operating Procedures
(SOP) document(s) in advance of the inspection. These documents were reviewed and editorial
and substantive revision requirements and recommendations were made by this program outside
of this formal report process. Although subsequent revisions were not requested to be submitted,
they must be completed within 1 year.

The laboratory is reminded that all changes made in response to the Findings,
Recommendations or Comments listed in this report must be incorporated in the Quality
Assurance (QA)/Standard Operating Procedures (SOP) document(s). The laboratory must
ensure the method is being performed as stated, references to methods are accurate, and the
QA and/or SOP document(s) is/are in agreement with approved practice and regulatory
requirements. In some instances, the laboratory may need to create a SOP to document how
new functions or policies will be implemented.

Contracted analyses are performed by Environment 1, Inc. (Certification #10), Pace Analytical
Services, Inc. - Huntersville (Certification #12), Environmental Testing Solutions, Inc. (Certification
#600) and Katahdin Analytical Services, LLC. (Certification #341).

III. FINDINGS, REQUIREMENTS, COMMENTS AND RECOMMENDATIONS:

Proficiency Testing

Comment: The laboratory did not have a Standard Operating Procedure (SOP) for Proficiency
Testing (PT) samples. The North Carolina Administrative Code, 15A NCAC 2H .0805 (a) (7)
states: Each laboratory shall develop and maintain a document outlining the analytical quality
control practices used for the parameters included in their certification. Supporting records shall
be maintained as evidence that these practices are being effectively carried out. Acceptable
corrective action (i.e., a SOP for PT samples was written between day 1 and 2 of the inspection
with an implementation date of 3/16/2016) was performed on 3/16/16 and observed by the
inspector to be adequate. No further response is necessary for this Finding.

Chlorine, Total Residual – Hach 10014 ULR (Aqueous)
Dissolved Oxygen – Hach 10360 2011, Rev. 1.2 (LDO) (Aqueous)
Conductivity – Standard Methods, 2510 B-1997 (Aqueous)
pH – Standard Methods, 4500 H+B-2000 (Aqueous)
Temperature – Standard Methods, 2550 B-2000 (Aqueous)

Comment: The benchsheets did not document the instrument identification. The NC WW/GW LC
Approved Procedure for the Analysis of Total Residual Chlorine, The NC WW/GW LC Approved
Procedure for the Analysis of Dissolved Oxygen, The NC WW/GW LC Approved Procedure for
the Analysis of Specific Conductance (Conductivity), The NC WW/GW LC Approved Procedure
for the Analysis of Temperature and The NC WW/GW LC Approved Procedure for the Analysis of
pH documents state: The following must be documented in indelible ink whenever sample
analysis is performed: Instrument identification. Acceptable corrective action (i.e., revised
benchsheets including the instrument identification with an implementation date of 3/16/2016)
was performed on 3/15/2016 and observed by the inspector to be adequate. No further
response is necessary for this Finding.

Dissolved Oxygen – Hach 10360 2011, Rev. 1.2 (LDO) (Aqueous)
Conductivity – Standard Methods, 2510 B-1997 (Aqueous)
pH – Standard Methods, 4500 H+B-2000 (Aqueous)

Comment: The benchsheet did not document the units of measure for the calibration. The North
Carolina Administrative Code, 15A NCAC 2H .0805 (a) (7) (H) states: All laboratories must use
printed laboratory bench worksheets that include a space to enter the signature or initials of the
analyst, date of analyses, sample identification, volume of sample analyzed, value from the
measurement system, factor and final value to be reported and each item must be recorded
each time samples are analyzed. Acceptable corrective action (i.e., revised benchsheets
including units of measure for the calibration with an implementation date of 3/16/2016) was
performed on 3/15/2016 and observed by the inspector to be adequate. No further response is
necessary for this Finding.

Conductivity – Standard Methods, 2510 B-1997 (Aqueous)

Comment: The lab was not rinsing the probe with three portions of 0.01M KCl solution before the
fourth portion is used to calibrate the instrument. Standard Methods, 2510 B-1997. (4) (a) states:
Rinse conductivity cell with at least three portions of 0.01M KCl solution. Notification of
acceptable corrective action (i.e., a statement that the probe is rinsed with three portions of
0.01M KCl prior to determining the cell constant with an implementation date of 3/17/2016) was
received by email on 4/1/2016. No further response is necessary for this Finding.

Comment: The lab was not rinsing the probe with at least one portion of sample before using the
final portion for sample analysis. Standard Methods, 2510 B-1997. (4) (b) states: Thoroughly rinse
cell with one or more portions of sample. Adjust temperature of a final portion to about 25°C.
Measure sample resistance or conductivity and note temperature to ± 0.1°C. Notification of
acceptable corrective action (i.e., a statement that the probe is rinsed with at least one portion of
sample prior to sample analysis with an implementation date of 3/17/2016) was received by email
on 4/1/2016. No further response is necessary for this Finding.

Residue, Total – Standard Methods, 2540 B-1997 (Aqueous)

Comment: The lab was not initially drying samples at 98°C to prevent spattering. Standard
Methods, 2540 B-1997. (3) (b) states: When evaporating in a drying oven, lower temperature to
approximately 2°C below boiling to prevent splattering. Notification of acceptable corrective
action (i.e., a statement that samples are initially dried at 98°C to prevent spattering with an
implementation date of 3/15/2016) was received by email on 4/1/2016. No further response is
necessary for this Finding.

Nitrogen, Ammonia – Standard Methods, 4500 NH3 D-1997 (Aqueous)
Nitrogen, NO3+NO2 – Standard Methods, 4500 NO3 E-2000 (Aqueous)
Nitrogen, Total Kjeldahl – Standard Methods, 4500 Norg C-1997 (Standard Methods, 4500
NH3 C-1997) (Aqueous)

Comment: The lab was not adding preservative to reagent blanks and laboratory fortified blanks.
Standard Methods, 1020 B-2011. (5) states: A reagent blank (method blank) consists of reagent
water (see section 1080) and all reagents (including preservatives) that normally are in contact
with a sample during the entire analytical procedure. The reagent blank is used to determine
whether, and how much, reagents and the preparative analytical steps contribute to measurement
uncertainty. Standard Methods, 1020 B-2011. (6) states: A laboratory fortified blank [laboratory
control standard (LCS)] is a reagent water sample (with associated preservatives) to which a
known concentration of the analyte(s) of interest has been added. An LFB is used to evaluate
laboratory performance and analyte recovery in a blank matrix. Notification of acceptable
corrective action (i.e., a statement that the reagent blanks and laboratory fortified blanks are being
preserved) was received by email on 4/1/2016 with an implementation dates of 3/15/2016 for
NO3+NO2, 3/21/2016 for Ammonia and 3/22/2016 for Total Kjeldahl Nitrogen (TKN). No further
response is necessary for this Finding.

Comment: The lab was not analyzing Laboratory Fortified Matrix Duplicates (LFMD). Standard
Methods, 4020 B-2009, Rev. 2011, Table 4020: I and (2) (g) states: When appropriate for the
analyte (Table 4020:I), include at least one LFM/LFMD daily or with each batch of 20 or fewer
samples. Notification of acceptable corrective action (i.e., a statement that the lab will analyze
LFMDs at the required frequency with implementation dates of 3/15/2016 for NO3+NO2,
3/21/2016 for Ammonia and 3/22/2016 for TKN) was received by email on 4/1/2016. No further
response is necessary for this Finding.

IV. PAPER TRAIL INVESTIGATION:

The paper trail consisted of comparing original records (e.g., laboratory benchsheets, logbooks,
etc.) and contract lab reports to Discharge Monitoring Reports (DMRs) submitted to the North
Carolina Division of Water Resources. Data were reviewed for Goldsboro WRF (NPDES permit
# NC0023949) for August, September and October 2015. No transcription errors were
detected. The facility appears to be doing a good job of accurately transcribing data.
