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 is spacious and well equipped. All equipment is well maintained. Records are well kept
and data appeared accurate.
Ili. FINDINGS REQUIREMENTS COMMENTS AND RECOMMENDATIONS:
General Laboratory
Comment: The balance weights had not been verified within the past five years. North Carolina
Wastewater/Groundwater Laboratory Certification Policy states: ASTM Class 1 and 2 weights must be
verified at least every 5 years. ASTM Class 1 weights (20 g to 25 kg) and ASTM Class 2 weights (10 g
to 1 mg) are equivalent to the NBS Class S weights specified in 15A NCAC 2H .0805 (a) (7) (K).
Demonstration of acceptable corrective action (i.e., new weights had already been ordered but had not
arrived) was provided at the time of the inspection. No further response is necessary for this finding.
Comment: The laboratory was not checking the balance used for reagent preparation with one standard
weight daily. The North Carolina Administrative Code, 15A NCAC 2H .0805 (a) (7) (K) states: The
analytical balance must be checked with one class S, or equivalent, standard weight each day used and
at least three standard weights quarterly. The values obtained must be recorded in a log and initialed by
the analyst. Demonstration of acceptable corrective action (i.e., laboratory staff created a form to
document the daily weight check and indicated that it would be put into use immediately) was provided
at the time of the inspection. No further response is necessary for this finding.
Comment: Error corrections were not dated when performed. North Carolina Wastewater/Groundwater
Laboratory certification Policy 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 change 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., this policy was
implemented on the day of the inspection) was received by email on March 19, 2012. 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 Hendersonville WWTP (NPDES permit #NC0025534) for May, June, and July, 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.
