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.
GENERAL COMMENTS:
The facility is clean, well -organized, and has all the equipment necessary to perform the analyses. The
lab personnel were eager to adopt recommendations and necessary changes and solve issues as soon
as possible.
Proficiency Testing r (PT) samples were analyzed for all certified parameters for the 2015 proficiency
testing calendar year and the graded results were 100% acceptable.
Contracted analyses are performed by Pace Analytical Services, Inc. — Huntersville (Certification #12).
Current Quality Assurance Policies for Field Laboratories and Approved Procedures for the analysis of
the facility's currently Certified Parameters were provided at the time of the inspection.
FINDINGS, REQUIREMENTS, COMMENTS AND RECOMMENDATIONS:
Documentation
Comment: The documentation of the annual temperature sensor verification did not include units of
measure (i.e., °C). The North Carolina Administrative Code, 15 NCAC '2H .0805 (g) (1) states: 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 or the analyst, and proper units of measure for all analyses.
Acceptable corrective action (i.e., units of measure (i.e., °C) were added to the temperature verification
documentation) was performed during the inspection. No further response is necessary for this
Finding.

Comment: The documentation of the annual temperature sensor verification did not include the serial
number of the NIST thermometer used for comparison. The Approved Procedure for the Analysis of
Temperature document states: The documentation must include the serial number of the NIST
traceable thermometer that was used in the comparison Acceptable corrective action (i.e., the NIST
thermometer serial number was added to the temperature verification documentation) was performed
during the inspection. No further response is necessary for this Finding.
Comment: Proper units of measure (i.e., ug/L) were not documented on the daily benchsheet for Total
Residual Chlorine. The result column was labeled "mg/L or ug/L", with the intention that one of the units
would be circled, which was not being done. The North Carolina Administrative Code, 15 NCAC 2H .0805
(g) (1) states: 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 or the analyst, and proper units of
measure for all analyses. Notification of acceptable corrective action (i.e., an updated benchsheet with the
results column only labeled as ug/L was implemented by January 23, 2016 was received by email on
January 23, 2016. No further response is necessary for this Finding.
Comment: The facility lacked traceability information. The facility was recording lot numbers for pH
buffers and Total Residual Chlorine reagents on the daily benchsheet, but there was no documentation
stating the vendor, expiration date, or date of receipt. The Quality Assurance Policies for Field
Laboratories document states: 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. Notification of acceptable corrective action (i.e., the facility
implemented by January 27, 2016 a laboratory receipt log with date received, vendor, and expiration
date) was received by email on January 27, 2016. No further response is necessary for this Finding.
Chlorine, Total Residual — Standard Methods, 4500 Cl G-2000
Comment: The low range calibration curve (i.e., program 86) had not been verified on the Hach DR1900.
A contract laboratory performed the meter calibration verification and only verified the high level curve
(i.e., program 82 with standard concentrations of 0.1, 0.2, 0.5, 1.0, and 2.0 mg/L) but assigned a true
value for the mid -range Gel®standard on program 86. The laboratory was analyzing compliance samples
and checking the Gel® standard on program 86 using that assigned value. The facility's permit limit is 28
ug/L and they were reporting sample concentrations below 25 ug/L as < 25 ug/L based off a curve
verification performed on a separate instrument. The Approved Procedure for the Analysis of Total
Residual Chlorine document states: Standard curve verification checks must be performed for the
standard curve and/or program used for sample analysis. 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. Notification of acceptable corrective action
(i.e., an acceptable calibration verification was performed on the low level program with calibration
standard concentrations of 20, 50, 100, 200, and 400 ug/L on January 19, 2016 setting the current
reporting limit at 20 ug/L. The Gel®standard concentration was verified as 204 ug/L on January 22, 2016.)
was received by email on January 23, 2016. No further response is necessary for this Finding.
pH — Standard Methods, 4500 H+ B-2000
Temperature — Standard Methods, 2550 B-2000
Comment: The analyst was writing a collection and analysis time for parameters measured in situ. The
collection time was the time the probe entered the water and the analysis time was the time that the
reading was deemed "stable". The Approved Procedure for the Analysis of pH and The Approved
Procedure for the Analysis of Temperature documents state: Alternatively, one time may be documented
for collection and analysis with the notation that samples are measured in situ or immediately at the

sample site. Notification of acceptable corrective action (i.e., a statement that one time is being recorded
and an updated benchsheet stating one time is recorded for samples collected in situ was implemented
by January 23, 2016) was received by email on January 23, 2016. No further response is necessary
for this Finding.
Proficiencv Testing
Comment: The preparation of PT samples was not being documented. This only applies to the Total
Residual Chlorine PT. The Proficiency Testing Requirements document states: PT samples received as
ampules must be diluted according to the PT provider's instructions. The preparation of PT samples must
be documented in a traceable log or other traceable format The diluted PT sample becomes a routine
environmental sample and is added to a routine sample batch for analysis. Notification of acceptable
corrective action (i.e., a statement that the PT provider's preparation instructions will be initialed and
dated from this point forward) was received by email on January 21, 2016. No further response is
necessary for this Finding.
Recommendation: The facility reported the 2015 pH PT sample to one decimal place. It is
recommended that pH values be reported to 2 decimal places on the PT report, as stated in the vendor's
instructions. Continue to report compliance data to 1 decimal.
IV. PAPER TRAIL INVESTIGATION:
The paper trail consisted of comparing original records (i.e., laboratory benchsheets) and contract lab
reports to Discharge Monitoring Reports (DMRs) submitted to the North Carolina Division of Water
Resources. Data were reviewed for NPDES permit #NC0004626 for March, July, and September 2015.
No transcription errors were detected. The facility appears to be doing a good job of accurately
transcribing data. Please continue to pay close attention to the reporting limit for the "non -detect" Total
Suspended Solids samples.
V. CONCLUSIONS:
All Findings noted during the inspection were adequately addressed prior to the completion of this report.
The inspectors would like to thank the staff for its assistance during the inspection and data review
process. No response is required.
