LOCAL PERSON(S) CONTACTED: Brenna Cook and Dinah Trammel
INTRODUCTION:
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.
11. 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. The laboratory has been proactive in keeping up with updates and changes
required by this Program, particularly in the area of consumable traceability.
All required Proficiency Testing (PT) samples have been analyzed for the 2017 PT calendar year
and the graded results were 100% acceptable.
Contracted analyses are performed by Environmental Testing Solutions, Inc. (Certification #600)
and the City of Asheville — North Fork WTP Laboratory (Certification #531).
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:
Documentation
A. Finding: The laboratory benchsheet was lacking pertinent data: instrument identification.
Requirement: The following must be documented in indelible ink whenever sample
analysis is performed: Instrument Identification. Ref: NC WW/GW LC Approved
Procedure for the Analysis of pH and NC WW/GW LC Approved Procedure for the
Analysis of Total Residual Chlorine.

C. Finding: The laboratory benchsheet was lacking pertinent data: true values of pH buffers
used for calibration.
Requirement: The following must be documented in indelible ink whenever sample
analysis is performed: True values of buffers used for calibration. Ref: NC WW/GW LC
Approved Procedure for the Analysis of pH.
C. Finding: The Total Residual Chlorine curve verification benchsheet was lacking pertinent
data: the value obtained for the reagent blank.
Requirement: The following must be documented in indelible ink whenever sample
analysis is performed: Value obtained for the reagent blank, when prepared standards
are used (verification of s'/2 the concentration of the lowest calibration standard). Ref:
NC WW/GW LC Approved Procedure for the Analysis of Total Residual Chlorine.
Comment: Environmental Testing Solutions, Inc. assists the laboratory with performing
the curve verification. A blank was analyzed and evaluated, but the results were not
documented. Environmental Testing Solutions, Inc. has been notified of this requirement.
IV. PAPER TRAIL INVESTIGATION:
The paper trail consisted of comparing original records (e.g., laboratory benchsheets, logbooks,
etc.) and contract lab reports to electronic Discharge Monitoring Reports (eDMRs) submitted to
the North Carolina Division of Water Resources. Data were reviewed for the Mills River
Regional WTP (NPDES permit # NC0085511) for February, March and April 2017. No
transcription errors were detected. The facility appears to be doing a good job of accurately
transcribing data.
V. CONCLUSIONS:
Correcting the above -cited Findings will help this laboratory to produce quality data and meet
Certification requirements. The inspector would like to thank the staff for their assistance during
the inspection and data review process. Please respond to all Findings and include
supporting documentation and implementation dates for each corrective action.
