This laboratory was inspected to verify its compliance with the requirements of 15A NCAC 2H .0800 for
the analysis of environmental samples.
GENERAL COMMENTS:
The findings noted do not apply to all operators and facilities. The report does not address specific
operators but is written so that issues of uniformity between operators can be addressed. The company
management and personnel are to be commended for the degree of uniformity they have already
achieved.
FINDINGS REQUIREMENTS COMMENTS AND RECOMMENDATIONS:
Documentation
Recommendation: Some operators have instituted consumable material tracking by recording lot
numbers of pH buffers (in use) with expiration dates in the front of their calibration logbooks. This is
recommended for all operators. It is also recommend that lot numbers and expiration dates for DPD (total
residual chlorine) be likewise documented.
Recommendation: It is recommended that when samples are taken in — situ (directly measured in the
stream or discharge) that this be documented on the bench sheet or in the logbook. If this is routine it can
be documented in the logbook or on the bench sheet as a footnote.
Recommendation: Some samples are left at a central location by the operators and picked up later by
laboratory staff. It is recommended that these coolers be sealed with custody tape. In order to document
that the samples have not been tampered with, the chain of custody should document that the custody
tape was intact upon receipt by the laboratory.
A. Finding: Some overwriting and cross out error corrections were observed.
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 responsible
individual must initial the correction and the date of change documented. All data and log
entries must be written in indelible ink. Pencil entries are not acceptable. Ref: North Carolina
Wastewater/Groundwater Laboratory Certification (NC WW/GW LC) Policy, 11/30/2007.
B. Finding: For some operators' documentation of instrument calibration (pH, Dissolved Oxygen)
or calibration verifications (Total Residual Chlorine) time was sporadic.
Requirement: Document instrument calibration times in order to verify calibration (or calibration
verification) was performed prior to sample analysis. Ref: Technical Assistance for Field Analysis
of pH, Rev. 02/2009, Technical Assistance for Field Analysis of Total Residual Chlorine, Rev.
8/2008, Technical Assistance for Field Analysis of Dissolved Oxygen, Rev. 7/2009.
Total Residual Chlorine — Standard Methods, 181h Edition, 4500 Cl G
C. Finding: At one facility calibration is not verified prior to sample analysis (high level).
Requirement: Verify calibration prior to analyzing compliance samples. Ref. Technical Assistance
for Field Analysis of Total Residual Chlorine, Rev. 8/2008,
D. Finding: For one facility samples are analyzed on the high level curve (program 80); however,
the daily calibration verification is analyzed on the low level curve (program 86) (170 lag/L).
Requirement: Each facility must have glassware, chemicals, supplies, equipment, and a source
of distilled or deionized water that will meet the minimum criteria of the approved methodologies.
Ref: 15A NCAC 02H .0805 (g) (4).
Comment: Findings C & D are from the same facility and arise from a single issue. Checking the
meter calibration verification using the wrong curve means that samples are analyzed on a curve
that is unverified (Finding D). The lowest gel standard may be used to verify both programs. Since
the values will not be identical a separate true value will need to be assigned to that standard for
each program. If the facility chooses to use a higher level gel -standard to verify program 80 a true
value must be assigned to that standard.
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 at least two facilities per operator from May and June 2008. 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 and implementing the recommendations 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.
