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 staff is congratulated for doing .a good job of maintaining the Field=Testing. Certification program.
' The facility' has all the equipment necessary to perform the analyses. All of the following comments are
new requirements or policies that have been implemented since the last inspection.
III. FINDINGS, REQUIREMENTS, COMMENTS AND RECOMMENDATIONS:
Documentation
A. Finding: The time the pH; and D.O. meters are: calibrated,: needs to be documented. This is
considered pertinent information.
Requirement: Data pertinent to each analysis must be maintained for, five years:. Certified data
must consist of- date collected, time. collected, samples site,. sample collector; and sample
analysis time. The field bench: sheets must provide a space for the signature of the analyst, and..
-proper units of measure for all analyses., Ref:.15A NCAC 2H :0805 (g)
LH - Standard Methods,'18th Edition, 4500 = H+ B.
B. ,Finding: The laboratory needs, to verify the Automatic Temperature Compensator(ATC)'of. the -
pH meter annually (every twelve months).
'Requirement: The following must be performed on an 'annual (12 month) basi:-
Automatic Temperature Compensator Check-(ATC) for pH meter, performed every 12 months

Page-:2
1: Take a buffer solution and cool to below 10°C and read the temperature. Analyze the buffer
solution- at that temperature. Document the temperature and the measured pH value
Obtained on the log sheet.
2. Raise the temperature of the buffer solution to approximately 25°C Document._the •
- temperature and the measured pH value on the log sheet.
3. 'Raise the temperature of the buffer solution to approximately 35°C. Document the
temperature and the measured pH value on the log sheet. •
4. Repeat with additional temperature adjustments .and pH readings as. necessary to ensure the
temperature usually measured for samples has been bracketed. As the temperature
increases .ordecreases,- the value of the buffer must be within ± Q;1-S.U. of the truevalue of
the buffer.
Ref: North.Carolina Wastewater/Groundwater Laboratory Certification (NC WW/GW LC) Policy
Statement February 2006
C. Finding: The temperature at which pH is measured is not documented.
- Requirement: Document the temperature at which- the pH sample(s) are analyzed. Ref: EPA
150.1-4.4; Standard Methods 18'h Edition Method 4500H B.1 b.
IV. PAPER TRAIL INVESTIGATION:
A review;of data was conducted. This consisted of comparing field testing records and, contract lab
reports to Discharge Monitoring Reports (DMRs) submitted to this Division. Data were- reviewed for
January, March, andr May 2007. No errors were noted:- Itappears the facility is doing' a good job of.
accurately, transcribing data. ,
CONCLUSIONS:
Correcting the above -cited findings will help this lab to produce quality data and meet certification'
requirements: Please respond to all lettered findings.
