Dear Mr. Tolson:
Enclosed is a report for the inspection performed on March 24, 2015 by Nick Jones. Since the
finding(s) cited during the inspection were all corrected prior to the completion of the enclosed
report, a response is not required. But please submit completed benchsheets after your next
sampling/analysis event in May as requested. The staff is commended for taking the initiative in
correcting the findings in such a timely manner. For certification maintenance, your laboratory must
continue to carry out the requirements set forth in 15A NCAC 2H .0800.
Copies of the checklists completed during the inspection may be requested from this office. Thank
you for your cooperation during the inspection. If you wish to obtain an electronic copy of this
report by electronic mail, or if you have questions or need additional information, please contact
me at [phone].

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 laboratory was clean and well organized. The facility has all the equipment necessary
to perform the analyses.
Proficiency Testing (PT) samples for the 2015 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, 2015.
Contracted analyses are performed by Environment 1, Inc. (Certification #10) and
Meritech, Inc. (Certification #165).
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: Error corrections were not performed properly. The NC WW/GW LC Quality
Assurance Policies for Field Laboratories document states: All documentation errors
must be corrected by drawing a single line through the error so that the original entry

Page 2
#5614 Ocracoke Sanitary District
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. Notification of acceptable
corrective action (i.e., a statement that as of 4/1/2015 the lab will henceforth make error
corrections according to the NC WW/GW LC policy) was received by email on 4/1/2015.
No further response is necessary for this finding.
Comment: The lab did not have a system of traceability for the documentation of
purchased materials and reagents. The NC WW/GW LC 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.
Consumable materials such as pH buffers and lots of pre -made standards are included
in this requirement. Demonstration of acceptable corrective action (i.e., laboratory
personnel implemented the traceability log provided by the inspector) was witnessed
during the inspection. No further response is necessary for this finding.
Temperature - Standard Methods, 2550 B-2000
Comment: The temperature sensor on the Dissolved Oxygen meter used to obtain
reported temperature values had not been checked against a National Institute of
Standards and Technology (NIST) traceable thermometer. The NC WW/GW LC
Approved Procedure for the Analysis of Temperature document states: Thermometers
and temperature measuring devices, used to measure temperature for compliance
monitoring, must be checked every 12 months against a NIST traceable thermometer.
The thermometer/meter readings must be less than or equal to 1°C from the NIST
traceable thermometer reading. The documentation must include the serial number of
the NIST traceable thermometer that was used in the comparison. Document any
correction that applies on both the thermometer/meter and on a separate sheet to be
filed. Notification of acceptable corrective action (i.e., documentation of the NIST traceable
thermometer verification) was received by email on 4/1/2015. No further response is
necessary for this finding.
Dissolved Oxygen - Standard Methods, 4500 O G-2001
pH - Standard Methods, 4500 H+ B-2000
Comment: The lab was not calibrating the pH or DO meter prior to use on each
analysis day. The NC WW/GW LC Approved Procedure for the Analysis of pH and The
NC WW/GW LC Approved Procedures for the Analysis of Dissolved Oxygen state:
Instruments are to be calibrated according to the manufacturer's calibration procedure
prior to analysis of samples each day compliance monitoring is performed. Notification of
acceptable corrective action (i.e., a statement that as of 4/1/2015 the lab will henceforth
begin calibrating the pH and DO meter prior to use on each analysis day) was received
by email on 4/1/2015. No further response is necessary for this finding.

Dissolved Oxygen - Standard Methods, 4500 O G-2001
pH - Standard Methods, 4500 H+ B-2000
Temperature - Standard Methods, 2550 B-2000
Comment: The laboratory did not have benchsheets for DO, pH and Temperature.
Sample results were written directly on the Discharge Monitoring Report. The North
Carolina Administrative Code, 15A NCAC 2H .0805 (a) (7) (H) states: All laboratories
must use printed bench worksheets that include a space to enter the signature or initials
of the analyst, date of analyses, sample identification, volume of samples analyzed,
value from the measurement system, factor and final value to be reported and each item
must be recorded each time samples are analyzed. Notification of acceptable corrective
action (i.e., a statement that as of 4/1/2015 the lab will henceforth implement the use of
the benchsheets supplied by the inspector) was received by email on 4/1/2015. The lab
only samples/ analyzes samples quarterly. Please submit a benchsheet after the next
sampling/ analysis event in May.
IV. PAPER TRAIL INVESTIGATION:
The paper trail consisted of comparing contract lab reports to Discharge Monitoring
Reports (DMRs) submitted to the North Carolina Division of Water Resources. Data
were reviewed for August and November, 2014 and February, 2015. No transcription
errors were detected. The facility appears to be doing a good job of accurately
transcribing data.
V. CONCLUSIONS:
All findings noted during the inspection were adequately addressed prior to the
completion of this report. The inspector would like to thank the staff for its assistance
during the inspection and data review process. Please submit your benchsheet after
the next sampling/ analysis event in May.
