Maintenance Inspection
Dear Mr. Gibert:
Enclosed is a report for the inspection performed on May 25, 2017 by Jason Smith. Where Finding(s)
are cited in this report, a response is required. Within thirty days of receipt, please supply this office with
a written item for item description of how these Finding(s) were corrected. Please describe the steps
taken to prevent recurrence and include an implementation date for each corrective action. If the
Finding(s) cited in the enclosed report are not corrected, enforcement actions may be recommended.
For Certification maintenance, your laboratory must continue to carry out the requirements set forth in
15A NCAC 21-1.0800.
A copy of the laboratory's Certified Parameter List at the time of the audit is attached. This list will reflect
any changes made during the audit. 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 email or if you have questions or need additional information, please
contact me at [phone] ext. 251.
Sincerely,

LABORATORY NAME: Town of Boiling Springs WWTP
NPDES PERMIT#: NC0071943
ADDRESS: 2556 Rockford Rd
Boiling Springs, NC 28017
CERTIFICATE #: 5013
DATE OF INSPECTION: May 25, 2017
TYPE OF INSPECTION: Field Municipal Maintenance
AUDITOR(S): Jason Smith
LOCAL PERSON(S) CONTACTED: Mike Gibert and Tyler Mullineaux
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.
GENERAL COMMENTS:
The facility has all the equipment necessary to perform the analyses. The laboratory analyst was
very forthcoming and receptive to implementing the necessary changes in response to the
Findings and Recommendations made during the inspection.
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 Pace Analytical Services, LLC — Huntersville, NC
(Certification #12).
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.
FINDINGS. REQUIREMENTS, COMMENTS AND RECOMMENDATIONS:
Documentation
A. Finding: Error corrections are not properly performed.
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.
Comment: Some instances of overwriting were noted.
Proficiency Testing
B. Finding: The laboratory is not analyzing Proficiency Testing (PT) samples in the same
manner as compliance samples.
Requirement: All PT samples are to be analyzed and the results reported in a manner
consistent with the routine analysis and reporting requirements of compliance samples
and any other samples analyzed according to the requirements of 15A NCAC 2H .0800.
Ref: Proficiency Testing Requirements, February 20, 2012, Revision 1.2.
Comment: PT samples are analyzed multiple times, but samples are not.
C. Finding: The laboratory is not documenting PT sample analyses in the same manner as
environmental samples.
Requirement: All PT sample analyses must be recorded in the daily analysis records as
for any environmental sample. This serves as the permanent laboratory record. Ref:
Proficiency Testing Requirements, February 20, 2012, Revision 1.2.
Comment: PT results are recorded on the benchsheet, but are written in the margins
rather than where sample results are recorded.
pH — Standard Methods, 4500 H+ B-2000 (Aqueous)
D. 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).
Temperature — Standard Methods, 2550 B-2000 (Aqueous)
E. Finding: The National Institute of Standards and Technology (NIST) traceable
thermometer is not accurate to ± 0.5 °C.
Requirement: Any temperature measuring device, used to measure temperature for
compliance monitoring, must be verified against a NIST traceable temperature
measuring device prior to initial use and re -verified at least every 12 months and any
time the instrument is serviced. NIST traceable temperature measuring devices used for
this verification must have a stated accuracy of at least + 0.5 °C. Ref: NC WW/GW LC
Approved Procedure for the Analysis of Temperature.
Comment: The NIST traceable thermometer accuracy was ± 1.0 °C and is used to
verify the temperature sensor of the pH meter.

pH — Standard Methods, 4500 H+ B-2000 (Aqueous)
Temperature — Standard Methods, 2550 B-2000 (Aqueous)
Comment: The pH meter is used for Temperature analyses.
Recommendation: The collection and analysis times are not clearly labeled. The space on the
benchsheet intended for documentation of the sample collection and analysis time is being
used to document the time of analysis of each individual pH calibration buffer. It is
recommended that the laboratory use these spaces for sample collection and analysis and only
record one individual time of calibration when pH meter calibration begins.
F. Finding: The laboratory benchsheet was lacking pertinent data: instrument
identification.
Requirement: The following must

The paper trail consisted of comparing original records (e.g., laboratory benchsheets, logbooks,
etc.) and contract lab reports to electronic Discharge Monitoring Reports (eDMRs) submitted to
the North Carolina Division of Water Resources. Data were reviewed for the Town of Boiling
Springs WWTP (NPDES permit # NC0071943) for January, February and March 2017. No
transcription errors were detected. The facility appears to be doing a good job of accurately
transcribing data.
V. CONCLUSIONS:
Correcting the above -cited Findings and implementing the Recommendation will help this
laboratory to produce quality data and meet Certification requirements. The inspector would like
to thank the staff for their assistance during the inspection and data review process. Please
respond to all Findings and include supporting documentation and implementation
dates for each corrective action.
