Maintenance Inspection
Dear Mr. Stainaker:
Dee Freeman
Secretary
Enclosed is a report for the inspection performed on July 28, 2011 by Jason Smith. I apologize for the delay in
getting this report to you. Where finding(s) are cited in this report, a response is required. Within 30 days of
receipt, please supply this office with a written item for item description of how these finding(s) were corrected.
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 email or if you have

This laboratory was inspected to verify its compliance with the requirements of 15A NCAC 2H .0800 for
the analysis of environmental samples.
., •
The laboratory was clean and well organized. The facility has all the equipment necessary to perform the
analyses. Current technical assistance and quality assurance documents were provided at the time of the
inspection. The requirements associated with Findings A, B, C, and D are new policies that have been
implemented by our program since the last inspection.
A. Finding: The laboratory needs to increase the documentation of purchased materials and
reagents.
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. 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. Ref: Quality Assurance Policies for Field
Laboratories.
Comment: The laboratory has been properly documenting solution preparation (e.g., preparation
of Potassium Permanganate for Total Residual Chlorine curve verifications).

B. Finding: Error corrections are not performed properly.
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.
C. Finding: Data that does not meet all quality control requirements is not qualified on the
Discharge Monitoring Report (DMR).
Requirement: When quality control (QC) failures occur, the laboratory must attempt to
determine the source of the problem and must apply corrective action. Part of the corrective
action is notification to the end user. If data qualifiers are used to qualify samples not meeting
QC requirements, the data may not be useable for the intended purposes. It is the responsibility
of the laboratory to provide the client or end -user of the data with sufficient information to
determine the usability of the qualified data. Where applicable, a notation must be made on the
DMR form, in the comment section or on a separate sheet attached to the DMR form, when any
required sample quality control does not meet specified criteria and another sample cannot be
obtained. Ref: Quality Assurance Policies for Field Laboratories.
Comment: The laboratory was not transcribing data qualifiers from the contract laboratory reports
to the DMR.
D. Finding: Proficiency Testing (PT) samples are not documented in the same manner as
environmental samples.
Requirement: 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. Ref: Quality
Assurance Policies for Field Laboratories.
Total• • Standard Methods,th 4500 Cl it
E. Finding: Four standards were used to perform the annual curve verification.
Requirement: Analyze a water blank to zero the instrument and then analyze a series of five
standards. The curve verification must check 5 concentrations (not counting the blank) that
bracket the range of the samples to be analyzed. This type of curve verification must be
performed at least every 12 months. The values obtained must not vary by more than 10% of the
known value for standard concentrations greater than or equal to 50 pg/L and must not vary by
more than 25% of the known value for standard concentrations less than 50 /Jg/L. The overall
correlation coefficient of the curve must be >_0.995. Ref: Technical Assistance for Field Analysis of
Total Residual Chlorine. Please submit a copy of the curve verification with the reply to this
report.
Comment: Curve verifications prior to 2010 were performed properly. In 2010, the laboratory
changed the concentrations that were verified, and at that time did not analyze one of the
standards that had been previously verified.

Recommendation: It is recommended that the laboratory verify the internal calibration using
the following concentrations: 20, 40, 50, 200, and 400 pg/L.
Comment: The lowest standard verified determines the reporting limit. If the recommended
concentrations are verified, the reporting limit would be 20 ug/L and any values below 20 lig/L
would be reported as <20,ug/L.
PAPER TRAIL INVESTIGATION:
The paper trail consisted of comparing field testing records and contract lab reports to Discharge
Monitoring Reports (DMRs) submitted to the North Carolina Division of Water Quality. Data were
reviewed for the Woodfin Water District Plant (NPDES permit #NC0083178) for January, February,
and March, 2011. No transcription errors were detected. The facility appears to be doing a good job of
accurately transcribing data.
Correcting the above -cited findings and implementing the recommendation will help this lab 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.
