Maintenance Inspection
Dear Ms. Diedrich:
Enclosed is a report for the inspection performed on August 2, 2011 by Jason Smith. 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 email, or if you have
questions or need additional information please contact me at 828-296-4677.
Sincerely,
Gary Francies

This laboratory was inspected to verify its compliance with the requirements of 15A NCAC 2H .0800 for
the analysis of environmental samples.
II. GENERAL COMMENTS:
The laboratory was clean and well organized. The facility has all the equipment necessary to perform the
analyses. Proficiency testing samples have been analyzed for all certified parameters for the 2011
proficiency testing calendar year and the graded results were 100% acceptable. Laboratory staff are
commended for keeping up to date with most of the recent changes in certification policies.
Proficiency Testing
Comment: Proficiency testing (PT) samples were not analyzed and documented in the same manner
as environmental samples. Multiple replicates were analyzed and the results were not documented on
the normal daily benchsheet. The Quality Assurances for Field Laboratories states: The analysis of
proficiency testing (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., the laboratory stated that all future PT samples would be analyzed and documented in the same
manner as environmental samples) was received by email on August 2, 2011. No further response is
necessary for this finding.
Total Residual Chlorine — Standard Methods, 18th Edition, 4500 Cl G
Comment: The laboratory was using an incorrect reporting limit. The curve was verified down to 27,ug/L,
however results were only reported down to 50 pg/L. The Technical Assistance for Field Analysis of Total
Residual Chlorine states: 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. Notification of acceptable corrective action (i.e., the
laboratory stated that all future results will be reported down to the lowest standard verified during the
annual curve verification) was received by email on August 2, 2011. No further response is necessary
for this finding.
Proficlen2y Testing
Total Residual Chlorine — Standard Methods, 18th Edition, 4500 CI G
Recommendation: The laboratory orders and analyzes low level Total Residual Chlorine (i.e., pg/L) PT
samples. The analysis is performed on the regular level curve (i.e., mg/L), which is the curve used for
environmental samples. This causes the results of the sample to be reported to two decimals and in
mg/L. Although this has not caused the laboratory to receive unacceptable results, it is a possible source
of error. Since the facility has a permit limit of 0.1 mg/L, the analysis and reporting of low level PT
samples is not required. It is recommended that the laboratory analyze regular level Total Residual
Chlorine PT samples in future studies.
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 Outfalls 001, 002, and 005 for January 2011. 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.
