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.
II. GENERAL COMMENTS:
The facility has all the equipment necessary to perform the analyses.
Proficiency Testing (PT) samples for the 2015 proficiency testing calendar year have not yet been
analyzed. The laboratory is reminded that these results must be submitted to this office directly from the
vendor by September 30, 2015.
Contracted analyses are performed by Environmental Chemists, Inc. (Certification #94).
Current quality assurance policies for Field Laboratories and approved procedures for the analysis of the
facility's currently certified parameters were provided at the time of the inspection.
The laboratory is certified for temperature; however, it is not listed on the discharge permit. The laboratory
is considering dropping the parameter from their Certification.
The requirement associated with Finding A has been implemented by our program since the last
inspection.
III. FINDINGS, REQUIREMENTS, COMMENTS AND RECOMMENDATIONS:
Documentation
Comment: The laboratory benchsheet was missing the instrument identification for all parameters. The
NC WW/GW LC Approved Procedure for the Analysis of pH and NC WW/GW LC Approved Procedure
for the Analysis of Temperature documents state: The following must be documented in indelible ink

#5465 S & J Villari Livestock
whenever sample analysis is performed: Instrument Identification. This requirement is a new policy that
has been implemented by our program since the last inspection. Notification of acceptable corrective
action (i.e., a statement that an updated benchsheet, which was provided by the auditor and includes
instrument identifications for all parameters, would be put into use on 4/2/15) was received by email on
4/1/15. No further response is necessary for this finding.
Comment: The laboratory needed to increase the documentation of purchased materials and reagents.
The Quality Assurance Policies for Field Laboratories document states: All chemicals, reagents,
standards and consumables used by the laboratory must have the following information documented:
Date Received, Date Opened (in use), Vendor, Lot Number, and Expiration Date. Consumable materials
such as pH buffers and lots of pre -made standards are included in this requirement. An auditor -supplied
Lab Supply Receipt Log showing all required documentation for reagents currently in use was filled out
and implemented during the inspection. No further response is necessary for this finding.
Quality Control
Comment: Temperature is being taken in order to document thermal preservation of sub -contract
samples and is not reported for compliance monitoring.
Recommendation: It is recommended that the digital thermometer be labeled with its correction factor
and that factor be applied to any documented temperature readings.
Proficiency Testing
A. Finding: The laboratory is not documenting Proficiency Testing (PT) sample analyses in the
same manner as environmental samples.
Requirement: All PT sample analyses must be recorded in the daily analysis records as for any
environmental sample. This serves as the permanent laboratory record. Ref: Proficiency Testing
Requirements, February 20, 2012, Revision 1.2.
Comment: The analysis of 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.
pH — Standard Methods, 4500 H+B-2000
Comment: Environmental sample measurements were not bracketed with calibration and check
standard buffers. The pH meter was being calibrated with the 4 and 7 pH buffers. Both buffers were being
read as checks. NC WW/GW LC Approved Procedure for the Analysis of pH states: For routine work,
use a pH meter accurate and reproducible to 0.1 pH unit with a range of 0 to 14, equipped with a
temperature compensation device. Follow all manufacturers' recommendations for the calibration of the
meter each analysis day. The meter must be calibrated with at least two buffers. In addition to the
calibration standards, the meter must be verified with a third calibration standard. The calibration and
check standard buffers must bracket the range of the samples being analyzed. The analyst stated that he
would begin calibrating with 4, 7 and 10 pH buffers and checking with the meter calibration with the 7 pH
buffer. A new benchsheet was provided by the auditor with spaces to document the calibration in that
manner. Notification of acceptable corrective action (i.e., a statement that the updated calibration protocol
and benchsheet would be put into use on 4/2/15) was received by email on 4/1/15. No further response
is necessary for this finding.
B. Finding: Values were reported that exceed the method specified accuracy of 0.1 units.

#5465 S & J Villari Livestock
Requirement: By careful use of a laboratory pH meter with good electrodes, a precision of ±0.02
unit and an accuracy of ±0.05 unit can be achieved. However, ± 0.1 pH unit represents the limit of
accuracy under normal conditions, especially for measurement of water and poorly buffered
solutions. For this reason, report pH values to the nearest 0.1 pH unit. Ref: Standard Methods,
4500 H+ B-2000, (6).
IV. PAPER TRAIL INVESTIGATION:
The paper trail consisted of comparing original records (e.g., laboratory benchsheets, logbooks, etc.) and
contract lab reports to Discharge Monitoring Reports (DMRs) submitted to the North Carolina Division of
Water Resources. Data were reviewed for January and February, 2015. All data for samples collected on
01/02/2015 were reported as being collected on 01/04/2015. All data for samples collected on 02/04/2015
were reported as being collected on 02/02/2015. In order to avoid questions of legality, it is recommended
that you contact the appropriate Regional Office for guidance as to whether an amended Discharge
Monitoring Report will be required. A copy of this report will be made available to the Regional Office.
V. CONCLUSIONS:
Correcting the above -cited findings 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 and include an implementation date for each
corrective action.
