Maintenance Inspection
Dear Mr. Rizzo:
Enclosed is a report for the inspection performed on September 12, 2012 by Chet Whiting.
Since the finding(s) cited during the inspection were all corrected prior to the completion of the
enclosed report, a response is not required. The staff is commended for taking the initiative in
correcting the findings in such a timely manner. 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 electronic mail, or if you have questions or need additional information please
contact me at 828-296-4677.
Sincerely,

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 laboratory is neat and well organized and has all the equipment necessary to perform the
analyses.
Copies of the following documents were given to laboratory personnel during the inspection: Quality
Assurance Policies for Field Laboratories, Approved Procedure for Field Analysis of pH, Approved
Procedure for Field Analysis of Dissolved Oxygen and Approved Procedure for Field Analysis of
Temperature, Approved Procedure for Field Analysis of Total Residual Chlorine.
Contracted analyses are performed by K & W Labs (certificate #559) and PAR Labs (certificate #20).
III. FINDINGS REQUIREMENTS COMMENTS AND RECOMMENDATIONS:
Comment: No instances were observed, however the laboratory was not aware that any data that
does not meet all quality control requirements is required to be qualified on the Discharge Monitoring
Report, including contract laboratory data. The Quality Assurance Policies for Field Laboratories
document states: 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.

Comment: The laboratory needed to implement documentation of materials and reagents. 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, 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., a statement that traceability will be documented in the
sample log book) was received by email on October 4, 2012. No further response is necessary for
this finding.
Comment: The laboratory was not documenting the preparation of Proficiency Testing samples. 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., a statement that PT sample preparation will be
documented) was received by email on October 4, 2012. No further response is necessary for this
finding.
Comment: The laboratory was not documenting Proficiency Testing (PT) samples in the same manner
as environmental samples (i.e., on a benchsheet). Proficiency Testing Requirements, February 20,
2012, Revision 1.2. 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., a statement that PT samples will be documented in the same manner as
environmental samples) was received by email on October 4, 2012. No further response is necessary
for this finding.
IV. 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 Berryhill Elementary School (NPDES Permit N00028711) for April, May and June, 2012.
No transcription errors were detected. The facility appears to be doing a good job of accurately
transcribing data.
V. CONCLUSIONS:
All findings noted during the inspection were adequately addressed prior to the completion of this
report. The inspector would like to thank the staff for its assistance during the inspection and data review
process. No response is required.
