LABORATORY NAME: Farmville WWTP
NPDES PERMIT #: NC0029572
WATER QUALITY PERMIT : WQ0008778
ADDRESS: 2884 Chiquapin Rd.
Farmville, NC 27828
CERTIFICATE #: 5044
DATE OF INSPECTION: June 6, 2017
TYPE OF INSPECTION: Field Municipal Maintenance
AUDITOR(S): Tom Halvosa, Gary Francies, Dana Satterwhite and Todd
Crawford
LOCAL PERSON(S) CONTACTED: James Shoulders and Greg Sugg
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.
II. GENERAL COMMENTS:
The facility is neat and well organized and has all the equipment necessary to perform the
analyses. Benchsheets are well designed, easy to follow and concise. Records are well
organized and easy to retrieve. Staff were forthcoming and seemed eager to adopt necessary
changes.
The laboratory is commended for having Standard Operating Procedures (SOPs), which are not
yet required for Field Laboratories. The system of chemical and reagent traceability to source
materials was thorough and easy to follow.
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.
Requirements that reference 15A NCAC 2H .0805 (g) (1), stating "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", are
intended to be a requirement to document all pertinent information for historical reconstruction of
data. It is not intended to imply that existing records are not adequately maintained unless the
Finding speaks directly to that.
Contracted analyses are performed by Environment 1, Inc. (Certification # 10).

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
Comment: The laboratory was calibrating the National Institute of Standards and Testing (NIST)
thermometer used to verify the temperature sensors of laboratory meters more often than
required. The NC WW/GW LC Approved Procedure for the Analysis of Temperature document
states that NIST traceable thermometers used to verify the calibration of other thermometers or
temperature sensors (i.e., limited use only) must be recalibrated in accordance with the
manufacturer's recalibration date and the process documented. If no recalibration date is given,
the NIST traceable thermometer must be recalibrated every 5 years.
Documentation .
A. Finding: All original records are not being maintained for five years.
Requirement: Data pertinent to each analysis must be maintained for five years. Ref:
15A NCAC 2H .0805 (g) (1).
Comment: The testing data for Dissolved Oxygen and Temperature is initially written on a
piece of paper, transported back to the laboratory, and transferred to the benchsheet. It
was the laboratory's intent to maintain this original paperwork, however; because these
were individual, loose sheets of paper, much of it was unintentionally discarded.
Recommendation: It is recommended that if this system of documentation is maintained,
that the data be recorded on some type of bound notebook to conveniently keep pages
together and ensure the 5-year record retention requirement is met.
Total Residual Chlorine — Standard Methods, 4500 CI G-2000 (Aqueous)
Comment: As stated in the Approved Procedure for the Analysis of Total Residual Chlorine
document, it is permissible to use gel -type standards after the manufacturer's stated expiration
date if their true values are verified and documented, every 12 months.
B. Finding: Values less than the established reporting limit are being reported on the
electronic Discharge Monitoring Report (eDMR).
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: The laboratory currently has established a lower reporting limit of 15 pg/L by
having verified that concentration when verifying the latest calibration curve. Compliance
samples with concentrations less than that must be reported as < 15 lag/L on the eDMR.

#5044 Farmville VWVTP
C. Finding: The calibration check standard observed concentration column heading specifies
pg/L, but the value is documented in mg/L.
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).
Recommendation: It is recommended that the observed values be documented in pg/L,
as opposed to changing the column heading units to mg/L.
Dissolved Oxygen — Standard Methods, 4500 O G-2001 (Aqueous)
Recommendation: It was recommended that the benchsheet be amended to state that the
calibration is based on an altitude of 10 feet. The benchsheet was amended during the inspection
and immediately put into use.
pH — Standard Methods, 4500 H+ B-2000 (Aqueous)
Conductivity — Standard Methods, 2510 B-1997 (Aqueous)
Comment: Lot numbers of pH buffers and Conductivity standards were hard -printed onto
benchsheets. When the latest lots of pH 4 buffer and 447 pmho/cm Conductivity standard were
put into use, the benchsheet was not updated. However, all reagents and standards are also
documented on a reagent receipt log and it indicated the correct lot numbers by the date
opened/put in use. 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. 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. Acceptable corrective action (i.e., All hard -printed lot numbers
were removed from the benchsheet. The revised benchsheet was reprinted and immediately put
into use. Traceability is now maintained solely through the reagent receipt log.) was performed by
the laboratory and approved by the auditor during the inspection. No further response is
necessary for this Finding.
Conductivity —Standard Methods, 2510 B-1997 (Aqueous)
Comment: Cell constant determination is not required for the meter in use.
Temperature — Standard Methods, 2550 B-2000 (Aqueous)
Comment: The thermometer identification was incorrectly listed on the laboratory benchsheet.
The NC WW/GW LC Approved Procedure for the Analysis of Temperature document states: The
following must be documented in indelible ink whenever sample analysis is performed: Instrument
Identification. Acceptable corrective action (i.e., the benchsheet was updated to show that the DO
meter is used to measure temperature, then reprinted and immediately put into use) was
performed by the laboratory and approved by the auditor during the inspection. No further
response is necessary for this Finding.

IV. PAPER TRAIL INVESTIGATION:
The paper trail consisted of comparing original records (e.g., laboratory benchsheets, logbooks,
etc.) and contract lab reports to eDMRs submitted to the North Carolina Division of Water
Resources. Data were reviewed for Farmville WWTP (NPDES permit # NC0029572) for random
months in 2016, and March and May, 2017. 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 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.
