Maintenance Inspection
Dear Mr. Minchew:
Enclosed is a report for the inspection performed on November 6, 2019 by Anna Ostendorff. 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 2H .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. 259.
Sincerely,

I. INTRODUCTION:
Groundwater
This laboratory was inspected by a representative
Laboratory Certification (NC WW/GW LC) pog mftohverify is coe North mpliance ante with theolina requirements
of 15A NCAC 2H .0800 for the analysis of environmental samples.
II. GENERAL COMMENTS:
The facility is neat and well organized and has easy all
tothe
followequipment
concise. Records are well
analyses. Benchsheets are well rm the
designed, Y with updates
organized and easy to retrieve.
The
laboratory
is prepared t p mpleoactlment the ve in pew requirements as
and changes required by thisg
defined in the revised Rules. The laboratory supervisor was forthcoming and seemed eager to
adopt the necessary changes.
All required Proficiency Testing (PT) Sampleshavebeen analyzed for the 2019 PT Calendar Year
/o
and the graded results were 100 acceptable.
Contracted analyses are performed by Pace Analytical Services, LLC — Raleigh NC (Certification
# 67) and ETT Environmental, Inc (Certification # 686).
III. FINDINGS REQUIREMENTS COMMENTS AND RECOMMENDATIONS:
Documentation
A. Finding: The laboratory needs to increase the traceability documentation of purchased
materials and reagents. This is considered pertinent data.

Page 2
#5030 Ingersoll-Rand
Requirement: Chemical containers shall be dated when received and when opened.
Reagent containers shall be dated, identified, and initialed when prepared. Chemicals and
reagents exceeding the expiration date shall not be used. Chemicals and reagents shall
be assigned expiration dates by the laboratory if not given by the manufacturer. If the
laboratory is unable to determine an expiration date for a chemical or reagent, a one-year
time period from the date of receipt shall be the expiration date unless degradation is
observed prior to this date. The laboratory shall have a documented system of traceability
for all chemicals, reagents, standards, and consumables. Ref: 15A NCAC 2H .0805 (g)
(7).
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 (where specified). 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
primary standards, chemicals, reagents, and materials used for a period of five years.
Consumable materials such as pH buffers and lots of pre -made standards and/or media
solids and bacteria filters, etc. are included in this requirement. Ref: NC WW/GW LC
Policy.
Comment: Dates received and opened were written on the pH buffer bottles. While this
can provide a traceability link to analyses by looking at the dates that the chemicals were
in use, that link is lost once the bottles are discarded. A log sheet that may be used for
documenting traceability was provided by email November 8, 2019.
B. Finding: The units of measure (i.e., Standard Units or S.U.) are not documented on the
benchsheets.
Requirement: All laboratories shall use printable laboratory benchsheets. Certified Data
shall be traceable to the associated sample analyses and shall consist of: the proper units
of measure. Each item shall be recorded each time samples are analyzed. Ref: 15 NCAC
2H .0805 (g) (2) (Q.
Reporting
C. Finding: The laboratory does not report results of all tests on the characteristics of the
effluent.
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 the monthly
report forms. Ref: 15A NCAC 213.0506 (b) (3) (J).
Comment: The permit does not require Temperature monitoring. The laboratory is
voluntarily measuring and documenting Temperature of the Effluent when analyzing the
pH compliance sample. The laboratory may discontinue analyzing Temperature or
continue analyzing Temperature and report the results in the comment section on the
DMR.
pH — Standard Methods, 4500 H+ B-2011 (Aqueous)

#5030 Ingersoll-Rand
D. Finding: Values are 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-2011. (6).
Comment: Per PT Vendor instructions, the PT Sample results should be reported to two
decimal places.
Recommendation: The laboratory currently reports pH sample results to two decimal
places. It is recommended that the laboratory continue to measure and document sample
results on the benchsheet to two decimal places, and to round to the nearest 0.1 S.U.
when reporting results on the DMR.
Temperature — Standard Methods, 2550 B-2010 (Aqueous)
Recommendation: It is recommended that Temperature results be reported on the DMR in whole
numbers.
E. Finding: The annual temperature -measuring device check procedure is not performed
correctly.
Requirement: To check a compliance temperature -measuring device, compare readings
at two temperatures that bracket the range of compliance samples routinely analyzed
against a National Institute of Standards and Technology (NIST) traceable temperature -
measuring device and record all four readings. The readings from both devices must
agree within 0.5 °C. Ref: NC WW/GW LC Approved Procedure for the Analysis of
Temperature.
Comment: The temperature -sensing device was verified at one temperature. The
laboratory was sending the pH meter used to measure temperature to a calibration
company out of state who is unfamiliar with NC WW/GW LC requirements.
IV. PAPER TRAIL INVESTIGATION:
The paper trail consisted of comparing original records (e.g., laboratory benchsheets, logbooks,
etc.) and contract lab reports to DMRs submitted to the North Carolina Division of Water
Resources. Data were reviewed for Ingersoll-Rand (NPDES permit # NC0079227) for April,
August and September 2019. No transcription errors were observed. The facility appears to be
doing a good job of accurately transcribing data.
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 their assistance during the inspection and data review process. Please
respond to all Findings and include supporting documentation, implementation dates
and steps taken to prevent recurrence for each corrective action.
