INTRODUCTION:
This laboratory was inspected by representatives 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.
GENERAL COMMENTS:
The open and forthcoming culture of the lab was reassuring and appreciated. In some instances,
the lab began the corrective action process immediately.
The laboratory has multiple operators, which in some cases, service many permits. The laboratory
indicated that this report would be shared with the other Aqua North Carolina, Inc. divisions, so
that they may determine where any similar deficiencies in compliance may be and voluntarily
correct them.
All required Proficiency Testing (PT) samples for the 2017 PT calendar year have not yet been
analyzed. The laboratory is reminded that results must be received by this office directly from the
vendor by September 30, 2017.
Contracted analyses are performed by Environmental Conservation Laboratories, Inc.
(Certification # 591).

#5051 Aqua North Carolina, Inc. Eastern NC
Current Quality Assurance Policies for Field Laboratories and Approved Procedure documents for
the analysis of the facility's currently certified Field Parameters were provided at the time of the
inspection.
III. FINDINGS, REQUIREMENTS, COMMENTS AND RECOMMENDATIONS:
Quality Control
Recommendation: It is recommended that the laboratory implement equipment maintenance
logs.
A. Finding: The auto-pipettors have not been calibrated annually as required.
Requirement: Mechanical volumetric liquid -dispensing devices (e.g., fixed and adjustable
auto-pipettors, bottle -top dispensers, etc.), used for critical measurements, must be
calibrated at least every twelve months and documented. Each liquid -dispensing device
must meet the manufacturer's statement of accuracy. For variable volume devices used at
more than one setting, check the accuracy at the maximum, middle and minimum values.
Testing at more than three volumes is optional. When a device capable of variable
settings is dedicated to dispense a single specific volume, calibration is required at that
setting only. Ref: Quality Assurance Policies for Field Laboratories,
B. Finding: Data that does not meet all QC requirements on contract laboratory reports (i.e.,
qualified data) is not qualified on the eDMR.
Requirement: When Quality Control (QC) failures occur, the laboratory must attempt to
determine the source of the problem and must apply corrective action. Part of the
corrective action is notification to the end user. If data qualifiers are used to qualify
samples not meeting QC requirements, the data may not be useable for the intended
purposes. It is the responsibility of the laboratory to provide the client or end -user of the
data with sufficient information to determine the usability of the qualified data. Where
applicable, a notation must be made on the electronic Discharge Monitoring Report
(eDMR) form, in the comment section when any required QC does not meet specified
criteria and another sample cannot be obtained. Ref: Quality Assurance Policies for Field
Laboratories.
Comment: For help accessing the comments section on the eDMR contact Tom Moore
at 919-707-8945 or [e-mail].
Documentation
C. Finding: Error corrections are not always performed properly.
Requirement: All documentation errors must be corrected by drawing a single line
through the error so that the original entry remains legible. Entries shall not be obliterated
by erasures or markings. Wite-Out®, correction tape or similar products designed to
obliterate documentation are not to be used. Write the correction adjacent to the error.
The correction must be initialed by the responsible individual and the date of change
documented. All data and log entries must be written in indelible ink. Pencil entries are not
acceptable. Ref: Quality Assurance Policies for Field Laboratories.
D. Finding: The laboratory needs to increase the documentation of purchased materials and
reagents, as well as documentation of standards and reagents prepared in the laboratory.

#5051 Aqua North Carolina, Inc. Eastern NC
Requirement: All chemicals, reagents, standards and consumables used by the
laboratory must have the following information documented: Date Received, Date Opened
(in use), Vendor, Lot Number, and Expiration Date. A system (e.g., traceable identifiers)
must be in place that links standard/reagent preparation information to analytical batches
in which the solutions are used. Documentation of solution preparation must include the
analyst's initials, date of preparation, the volume or weight of standard(s) used, the solvent
and final volume of the solution. This information as well as the vendor and/or
manufacturer, lot number, and expiration date must be retained for chemicals, reagents,
standards and consumables used for a period of five years. Consumable materials such
as pH buffers and lots of pre -made standards are included in this requirement. Ref:
Quality Assurance Policies for Field Laboratories.
Comment: Some of the laboratory's operators could not verify the expiration date of their
pH buffers. The operators would take aliquots from the main pH buffer reservoirs located
at the laboratory headquarters. However, they did not write the new expiration dates or lot
#s associated with the new aliquots on their buffer containers or on a separate document.
The main buffer reservoirs located at headquarters were not expired, but there was no
way to confirm that these were the buffers being currently utilized by every operator.
E. Finding: Process control data is not documented as such.
Requirement: Data pertinent to each analysis must be maintained for five years. Certified
Data must consist of date collected, time collected, sample site, sample collector, and
sample analysis time. The field benchsheets must provide a space for the signature or
initials of the analyst, and proper units of measure for all analyses. Ref: 15A NCAC 2H
.0805 (g) (1).
Comment: Several instances of data for various parameters did not have calibration data
associated with it. After checking permit sampling frequency requirements, it was
discovered that this data, collected without supporting calibrations or calibration checks,
was for process control and not for compliance monitoring purposes. Since neither the
process control nor the compliance data were identified as such, it appeared that all the
data was for compliance purposes and that some of it was lacking necessary components
of Quality Assurance.
Temperature — Standard Methods, 2550 B-2000 (Aqueous)
F. Finding: The laboratory benchsheet is lacking pertinent data: collection/analysis time,
instrument identification (e.g., serial number).
Requirement: The following must be documented in indelible ink whenever sample
analysis is performed: time of sample collection, time of sample analysis, instrument
identification. Ref: NC WW/GW LC Approved Procedure for the Analysis of Temperature.
Comment: The benchsheets contained spaces for collection and analysis time for
Temperature. Temperature samples are measured in -situ (i.e., collection and analysis
times are the same). The benchsheet needs clarification. Sometimes the benchsheet had
the same time in both spaces. Other times one of the spaces would be empty.

#5051 Aqua North Carolina, Inc. Eastern NC
Dissolved Oxygen — Standard Methods, 4500 O G-2001 (Aqueous)
Dissolved Oxygen — Hach 10360-2011, Rev. 1.2 (LDO) (Aqueous)
G. Finding: The laboratory benchsheet is lacking pertinent data: meter calibration time, units
(i.e., mg/L.), instrument identification (e.g., serial number) and analyst's initials.
Requirement: The following must be documented in indelible ink whenever sample
analysis is performed: meter calibration time, units (i.e., mg/L), instrument identification,
collector's/analyst's name or initials. Ref: NC WW/GW LC Approved Procedure for the
Analysis of Dissolved Oxygen.
H. Finding: Some of the meters are not being calibrated in moist air for the air calibration.
Requirement: The laboratory must use moist air for the air calibration. This is
accomplished by calibrating the electrode in an environment with a high relative humidity.
Using dry air for the calibration can result in errant readings. Ref: NC WW/GW LC
Approved Procedure for the Analysis of Dissolved Oxygen.
Comment: Some of the meters are being calibrated with the probe submerged in water.
Recommendation: In at least one instance the probe was being calibrated by holding the
tip of the probe casing to the mouth of a partially filled water bottle. However, the probe
housing is vented and does not allow for an adequate seal to create water saturated air. It
is recommended that probes with a vented probe housing be calibrated with the probe
inside a baggie containing a small amount of water and a rubber band placed tightly
around the probe shaft to create an airtight seal.
I. Finding: The permit requires once per week monitoring. The facility voluntarily analyzes
Dissolved Oxygen samples daily but does not report all the data as required.
Requirement: The results of all tests on the characteristics of the effluent, including but
not limited to NPDES Permit Monitoring Requirements, shall be reported on monthly report
forms. Ref: 15A NCAC 02B .0506 (b) (3) (J).
pH — Standard Methods, 4500 H+113-2000 (Aqueous)
Recommendation: It is recommended that the laboratory not reuse calibration buffers. A fresh
aliquot should be used daily. Currently, the laboratory is using the same aliquot of buffer solution
for three months.
J. Finding: The laboratory benchsheet is lacking pertinent data: meter calibration, meter
calibration time, true value of calibration buffers, true value of the check buffer, value
obtained for the check standard buffer (verification of ± 0.1 S.U.), analysis time, instrument
identification (e.g., serial number), analysts initials.
Requirement: The following must be documented in indelible ink whenever sample
analysis is performed: meter calibration, meter calibration time, true value of calibration
buffers, true value of the check buffer and value obtained for the check standard buffer
(verification of ± 0.1 S.U.), analysis time, instrument identification, collector's/analyst's
name or initials. Ref: NC WW/GW LC Approved Procedure for the Analysis of pH.

#5051 Aqua North Carolina, Inc. Eastern NC
K. Finding: Some of the instruments are not being calibrated according to the
manufacturer's calibration procedure prior to analysis of samples each day compliance
monitoring is performed.
Requirement: Instruments are to be calibrated according to the manufacturer's calibration
procedure prior to analysis of samples each day compliance monitoring is performed. Ref:
NC WW/GW LC Approved Procedure for the Analysis of pH.
Comment: Some of the meters are only being calibrated weekly for some permits where
pH is required to be reported five times per week.
L. Finding: The laboratory is not analyzing a check standard buffer after calibration and prior
to sample analysis.
Requirement: The meter must be calibrated with at least two buffers. In addition to the
calibration standards the meter must be verified with a third calibration standard. The
calibration and check standard buffer must bracket the range of the samples being
analyzed. The check standard buffer must read within a range of ± 0.1 pH units to be
acceptable. Ref: NC WW/GW LC Approved Procedure for the Analysis of pH.
Comment: The laboratory thought a 2-point calibration was being performed with a
calibration check (i.e., the laboratory thought the first two buffers being analyzed were the
calibration and the third was the calibration check). However, the meter was interpreting
the assumed calibration check buffer as a third calibration point and no calibration check
buffer was being analyzed.
M. Finding: The laboratory is not analyzing a post analysis check standard buffer when
analyses are performed at multiple locations.
Requirement: When performing analyses away from the certified laboratory's primary
location, a post analysis calibration verification using the check standard buffer must be
analyzed at the end of the run. Ref: NC WW/GW LC Approved Procedure for the Analysis
of pH.
Recommendation: It is recommended that in addition to analyzing a post -analysis check
standard buffer, a mid -day check standard buffer must also be analyzed if multiple
locations are visited over an extended period of time. The post analysis check standard
buffer(s) must read within ±0.1 S.0 or corrective actions must be taken.
N. Finding: Values were reported that exceed the method specified accuracy of 0.1 units.
Requirement: By careful use of a laboratory pH meter with good electrodes, a precision
of ±0.02 unit and an accuracy of ±0.05 unit can be achieved. However, ± 0.1 pH unit
represents the limit of accuracy under normal conditions, especially for measurement of
water and poorly buffered solutions. For this reason, report pH values to the nearest 0.1
PH unit. Ref: Standard Methods, 4500 H+ B-2000. (6).
Chlorine, Total Residual - Hach 10014 ULR (Aqueous)
Chlorine, Total Residual - Standard Methods, 4500 Cl G-2000 (Aqueous)
Recommendation: Where applicable, it is recommended to indicate on the eDMR that UV is the
primary means of disinfection when no Total Residual Chlorine values are reported.

#5051 Aqua North Carolina, Inc. Eastern NC
Recommendation: It is recommended that the following concentration levels are chosen for the
annual low-level Total Residual Chlorine calibration verification: 10 (or 20 depending on the permit
limit), 30, 50, 200 and 400 µg/L. The first level (i.e., 10 or 20 µg/L) needs to be at or below your
permitted reporting limit. The second level (i.e., 30 µg/L) needs to be between the reporting limit
and the compliance limit (i.e., 50 µg/L). The third level (i.e., 50 µg/L) needs to be at the
compliance limit. The fourth level (i.e., 200 µg/L) needs to be at the same concentration as the
gel standard (i.e., 200 µg/L) used for daily calibration verification. The fifth level (i.e., 400 µg/L)
needs to be high enough to hopefully bracket the annual PT sample, but still within the meter's
upper range limit (i.e., 500 jig/Q.
Comment: The laboratory was not verifying the instrument's factory set curve for regular level
Total Residual Chlorine every 12 months. The NC WW/GW LC Approved Procedure for the
Analysis of Total Residual Chlorine document states: Analyze a water blank to zero the instrument
and then analyze a series of five standards. The curve verification must check 5 concentrations
(not counting the blank) that bracket the range of the samples to be analyzed. This type of curve
verification must be performed at least every 12 months. The values obtained must not vary by
more than 10% of the known value. The overall correlation coefficient of the curve must be
z0.995. Notification of acceptable corrective action (i.e., completed Total Residual Chlorine
calibration verification worksheets containing acceptable curve verifications for all applicable
meters) was received by email on March 17, 2017. No further response is necessary for this
Finding.
Comment: The calibration curve verification instruction sheet does not reflect the dilution volumes
being prepared. The sheet says that 100-mL is being added to a 4-mL aliquot of standard, when
4-mL of standard is actually brought up to 100-mL in a volumetric flask. The instruction sheet
needs to be revised.
O. Finding: The laboratory benchsheet is lacking pertinent data: meter calibration, meter
calibration time, true value of the daily check standard, value obtained for the daily check
standard, value obtained for the reagent blank (i.e., for operators that use a liquid standard
for daily calibration), true value of the post analysis check standard, value obtained for the
post analysis check standard, sample collection time, analysis time, units (i.e., mg/L
or µg/L), instrument identification (e.g., serial number).
Requirement: The following must be documented in indelible ink whenever sample
analysis is performed: meter calibration and meter calibration time, true value of the check
standard, value obtained for the check standard, value obtained for the reagent blank,
when prepared standards are used (verification of <1h the concentration of the lowest
calibration standard), true value and value obtained for the post analysis check standard,
time of sample collection, time of sample analysis, all data must be reported in mg/L or
µg/L, instrument identification. Ref: NC WW/GW LC Approved Procedure for the Analysis
of Total Residual Chlorine.
Comment: On some benchsheets no units were observed, on others improper units were
observed (e.g., µg/L were on benchsheets containing only results reported in mg/L).
P. Finding: One of the annual 5-Standard, low-level calibration curves does not pass all
individual standard recovery criteria.
Requirement: The values obtained must not vary by more than 10% of the known value
for standard concentrations greater than or equal to 50 µg/L and must not vary by more
than 25% of the known value for standard concentrations less than 50 jig/L. The overall

#5051 Aqua North Carolina, Inc. Eastern NC
correlation coefficient of the curve must be >_0.995. Ref: NC WW/GW LC Approved
Procedure for the Analysis of Total Residual Chlorine.
Comment: The 10 µg/L standard in the curve verification for permit # NC0061719 did not
meet the ±25% recovery acceptance criterion.
Q. Finding: The laboratory is not verifying all Gel® Standards every 12 months.
Requirement: Purchased "Gel -type" or sealed liquid ampoule standards may be used for
daily standard curve verification only. These standards must be verified initially and every
12 months thereafter, with the standard curve. When this is done, these standards may be
used after the manufacturer's expiration date. It is only necessary to verify the gel or
sealed liquid standard which falls within the concentration range of the curve used to
measure sample concentrations. For example, if you are measuring samples against a low
range curve, a 200 pg/L standard would be verified, and not the 800 pg/L standard since
the 800 pg/L standard would be measured using a high range curve. Ref: NC WW/GW LC
Approved Procedure for the Analysis of Total Residual Chlorine.
R. Finding: Values less than the established reporting limit are being reported on the eDMR.
S
T.
Requirement: The concentrations of the calibration standards must bracket the
concentrations of the samples analyzed. One of the standards must have a concentration
equal to or below the lower reporting concentration for Total Residual Chlorine. The lower
reporting limit must be less than or equal to the permit limit. Ref: NC WW/GW LC
Approved Procedure for the Analysis of Total Residual Chlorine.
Comment: Any value less than the concentration of the lowest concentration standard
used for the annual curve verification must be reported as less than the value of that
lowest calibration standard.
Finding: Some of the calibration curves are not verified each day of sample analysis.
Requirement: When a five -standard annual standard curve verification is used, the
laboratory must check the calibration curve each analysis day. To do this, the laboratory
must analyze a calibration blank to zero the instrument and analyze a check standard
each day that samples are analyzed. The value obtained for the check standard must read
within 10% of the true value of the check standard. If the obtained value is outside of the
±10% range, corrective action must be taken. Ref: NC WW/GW LC Approved Procedure
for the Analysis of Total Residual Chlorine.
Finding: Some operators are not zeroing the instrument with a liquid calibration blank
when using liquid daily check standards.
Requirement: Zeroing the Instrument: For colorimetric analyses, a calibration blank must
be analyzed each day to zero the instrument prior to analyzing any standards, samples or
the reagent blank. A calibration blank is a volume of reagent water of the same matrix as
the calibration standards, but without the target analyte and without DPD. Ref: NC
WW/GW LC Approved Procedure for the Analysis of Total Residual Chlorine.
U. Finding: Some operators are not analyzing a reagent blank with prepared standards.
Requirement: Reagent Blank: A reagent blank (sometimes also referred to as a method
blank) is only required when laboratory water is used to make quality control and/or

#5051 Aqua North Carolina, Inc. Eastern NC
calibration standards. If you are using a sealed standard (e.g., gel) for your daily check
standard, a reagent blank would only be analyzed when preparing the annual 5-point
calibration curve or 5 annual calibration curve verification standards. Ref: NC WW/GW LC
Approved Procedure for the Analysis of Total Residual Chlorine.
Comment: A reagent blank is made from the same laboratory water source used to make
quality control and/or calibration standards with DPD. The concentration of reagent blanks
must not exceed 50% of the reporting limit (i.e., the lowest calibration or calibration
verification standard concentration), unless otherwise specified by the reference method,
or corrective action must be taken.
Comment: Some operators were using the reagent blank to zero the instrument.
V. Finding: The laboratory is analyzing the sample immediately upon adding the Hach DPD
powder pillow.
Requirement: Some examples of the allowed types of changes, provided the
requirements of this section are met include: (xiii) The use of prepackaged reagents. As
such, the proper procedure for using the packaged reagents would then be determined by
the manufacturer's instructions. Ref: Code of Federal Regulations, Title 40, Part 136;
Federal Register Vol. 77, No. 97, May 18, 2012; 136.6. (b) (4).
Requirement: For successful testing, especially in treated effluents, strict adherence to
the development time is necessary. Three to six minutes of development time are
sufficient to resolve all chloramine forms without significant error from competing
reactions. Ref: Hach Company, "Current Technology of Chlorine Analysis for Water and
Wastewater", 2002.
W. Finding: Results are being reported on the eDMRs for samples that are not analyzed.
Requirement: Frequency and Location. Except as otherwise provided herein, all industrial
establishments and units of government shall take influent, effluent and stream samples at
such locations and with such frequency as shall be necessary to conduct the tests and
analyses required by Rule .0508 of this Section. Ref: 15A NCAC 2B .0505 (c) (1).
Comment: The lab is reporting estimated results on the eDMRs for the weekends without
analyzing samples on the weekend. This could be perceived by a third party as falsified
data, which is defined in NC Administrative Code 15A NCAC 02H .0803 (6) as data or
information which has been made untrue by alteration, fabrication, omission, substitution,
or mischaracterization.

# The lack of data on the benchsheet suggests that no analysis was performed. The fact that values were reported on the eDMR could be
interpreted as falsified data by a third party.

#5051 Aqua North Carolina, Inc. Eastern NC
Due to the number of errors noted in the paper trail investigation it is recommended that a system of
checking the data entered on the eDMR be implemented. It would be beneficial to have a second person
review the accuracy of data transcription to the eDMR. At a minimum, the person entering the data should
review the transcriptions to the eDMR after some time has passed from the original data entry.
In order to avoid questions of legality and/or possible monitoring frequency violations, it is recommended
that you contact the appropriate Regional Office for guidance as to whether an amended eDMR will be
required. A copy of this report will be made available to the Regional Office.
V. CONCLUSIONS:
Correcting the above -cited Findings and implementing the Recommendations will help this laboratory to
produce quality data and meet Certification requirements. The inspector would like to thank the staff for
its assistance during the inspection and data review process. Please respond to all Findings and
include supporting documentation and implementation dates for each corrective action.
