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.
II. GENERAL COMMENTS:
The lab has all the equipment_ necessary to perform the analyses. Proficiency Testing (PT) samples have
been analyzed for all certified parameters for the 2012 proficiency testing calendar year and the graded
results were acceptable. Contracted analyses are performed by K&W Laboratories (Certification
#559).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.

Documentation
Comment: The laboratory needed to increase the documentation of purchased materials and reagents,
as well as documentation of standards and reagents prepared in the laboratory. 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. 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 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. This requirement is a new policy that
has been implemented by our program since the last inspection. Notification of acceptable corrective
action (i.e., preparation of Potassium Permanganate will be documented when made) was received by
email on September 26, 2012. Laboratory personnel created a traceability log for purchased materials
and reagents at the time of the inspection. No further response is necessary for this finding.

Comment: Error corrections were not dated when performed. The 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 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 chancre documented. All data and log entries must be written in
indelible ink. Pencil entries are not acceptable. This requirement is a new policy that has been
implemented by our program since the last inspection. Notification of acceptable corrective action (i.e.,
error corrections will be dated when performed) was received by email on September 26, 2012. No
further response is necessary for this finding.
Quality Control
Comment: The auto-pipettor has not been calibrated. The Quality Assurance Policies for Field
Laboratories document states: Mechanical volumetric liquid -dispensing devices (e.g., fixed and
adjustable auto-pipettors, bottle -top dispensers, etc.) must be calibrated at least every twelve months
and documented. Each liquid -dispensing device must meet the manufacturer's statement of accuracy.
For variable volume devices used at more than one setting, check the accuracy at the maximum,
middle and minimum values. Testing at more than three volumes is optional. When a device capable of
variable settings is dedicated to dispense a single specific volume, calibration is required at that setting
only. This requirement is a new policy that has been implemented by our program since the last
inspection. Notification of acceptable corrective action (i.e., the auto-pipettor will be calibrated prior to
being used) was received by email on September 26, 2012. No further response is necessary for this
finding.
Comment: The auto-pipettor is used to prepare the Total Residual Chlorine standards for verification of
the instrument's internal curve and to prepare the Proficiency Testing sample for analysis.
Proficiency Testing
Comment: The preparation of Proficiency Testing (PT) samples was not documented. The Proficiency
Testing Requirements, February 20, 2012, Revision 1.2. 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. This requirement is
a new policy that has been implemented by our program since the last inspection. Notification of
acceptable corrective action (i.e., PT instructions will be signed and dated to document preparation)
was received by email on September 26, 2012. No further response is necessary for this finding.
Comment: PT samples were not analyzed in the same manner as environmental samples. A known
sample was analyzed with the PT samples and multiple analyses were performed. The Quality
Assurance Policies for Field Laboratories document states: The analysis of PT samples is designed to
evaluate the entire process used to routinely report environmental analytical results. Therefore, PT
samples must be analyzed and the process documented in the same manner as environmental
samples. This requirement is a new policy that has been implemented by our program since the last
inspection. Notification of acceptable corrective action (i.e., PT will be analyzed in the same manner as
environmental samples) was received by email on September 26, 2012. No further response is
necessary for this finding.
Comment: The laboratory was not documenting PT sample analyses in the same manner as
environmental samples. The Proficiency Testing Requirements, February 20, 2012, Revision 1.2.
document states: All PT sample analyses must be recorded in the daily analysis records as for any

environmental sample. This serves as the permanent laboratory record. This requirement is a new policy
that has been implemented by our program since the last inspection. During the inspection, laboratory
personnel created an identical benchsheet to their normal benchsheet, except labeled for the PT, to be
used for PT analysis documentation. No further response is necessary for this finding.
Comment: Proper method codes were not reported with the PT results. The Proficiency Testing
Requirements, February 20, 2012, Revision 1.2. document states: Laboratories must also be careful to
designate the correct method code(s) being used for each PT sample result. To ensure that you are
reporting the correct method, review your certificate attachment (i.e., certified parameter list). If you are
using a method that is not listed on your certificate attachment (i.e., certified parameter list), please
contact your auditor so that your certificate can be updated. The method must include the entire method
reference as is written on your certificate attachment (i.e., certified parameter list). This requirement is a
new policy that has been implemented by our program since the last inspection. Notification of
acceptable corrective action (i.e., PT results will be reported with the correct method codes) was
received by email on September 26, 2012. No further response is necessary for this finding.
pH — Standard Methods 4500 H+ B
Comment: Values were reported that exceed the method specified accuracy of 0.1 units. Standard
Methods, 4500 H+ B-2000, (6) states: 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. The Discharge
Monitoring Report form was edited during the inspection to round pH results to one decimal place. No
further response is necessary for this finding.
Temperature — Standard Methods 2550 B
pH — Standard Methods 4500 H+ B
Comment: Temperature and pH are analyzed at the time of collection, but the benchsheet indicated that
they were analyzed later along with the Total Residual Chlorine sample. The North Carolina
Administrative Code, 15A 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, samples site,
sample collector, and sample analysis time. The field benchsheets must provide a space for the
signature of the analyst, and proper units of measure for all analyses. Laboratory personnel updated
the benchsheet to state "pH and Temperature analyzed at time of sampling" during the inspection. No
further response is necessary for this finding.
IV. PAPER TRAIL INVESTIGATION:
The paper trail consisted of comparing laboratory benchsheets and contract lab reports to Discharge
Monitoring Reports (DMRs) submitted to the North Carolina Division of Water Quality. Data were
reviewed for May, June, July, and August, 2012. The following errors were noted:
