I. 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.
II. GENERAL COMMENTS:
The laboratory was clean and well organized. The facility has all the equipment necessary to perform the
analyses. A system for traceability of standard and reagent preparation is in place and easy to follow.
Proficiency Testing (PT) samples have been analyzed for all certified parameters for the 2012 proficiency
testing calendar year and the graded results were 100% acceptable.
Benchsheets are very well designed and include all applicable information in terms of standard and
reagent traceability.
The laboratory has already begun to update Quality Assurance Plans and Standard Operating
Procedures in response to the recent updates to the Code of Federal Regulations.
The laboratory is reminded that any time changes are made to laboratory operations; the laboratory
must update the Quality Assurance (QA)/Standard Operating Procedures (SOP) document(s). Any
changes made in response to the Findings, Recommendations or Comments listed in this report must
be incorporated to insure the method is being performed as stated, references to methods are
accurate, and the QA and/or SOP document(s) is in agreement with approved practice and regulatory
requirements. In some instances, the laboratory may need to create a SOP to document how new
functions or policy will be implemented.
On May 18, 2012, EPA promulgated changes to the list of Clean Water Act (CWA) methods at 40 CFR
Part 136.3. This action, referred to as the Methods Update Rule (MUR) approves new methods, or
changes to existing methods, that affects over 100 EPA methods, Standard Methods, ASTM methods,
and other test procedures in Part 136 of Title 40 of the Code of Federal Regulations (CFR). The rule
also contains a number of clarifications relating to approved methods, sample preservation and holding

times, and method modifications. The final rule may be found at:
http://water.epa.gov/scitech/methods/cwa/update_index.cfm. The North Carolina
Wastewater/Groundwater Laboratory Certification (NC WW/GW LC) program will be asking certified
laboratories to move toward implementation of the new rule with changes fully implemented by the end
of 2012. Each laboratory will need to review the MUR and evaluate its effect on current laboratory
practices. These changes must be made in the laboratory’s Standard Operating Procedures and in
Quality Manuals, as well as any other place where the method is cited, e.g., reports, benchsheets,
logs, etc. During this transition period, inspection reports will refer to the methods employed at the
laboratory at the time of the inspection, but will reference the requirements in the most recently
approved version of the method. Any difficulties encountered with meeting the requirements of these
references by the date due may be addressed in the written corrective action response.
Contracted analyses are performed by Environmental Chemists, Inc. (Certification #94), Pace Analytical
Services, Inc. (Certification #67) and Meritech, Inc. (Certification #165).
The requirement associated with Finding A is a new policy that has been implemented by our program
since the last inspection.
III. FINDINGS, REQUIREMENTS, COMMENTS AND RECOMMENDATIONS:
Quality Control
Comment: All data is peer and/or supervisor reviewed.
Total Residual Chlorine – Standard Methods, 4500 Cl G - 2000
Comment: In addition to the annual 5-point curve verification, each day of analysis, the lab is analyzing
two liquid standards and a gel standard in the lab. The meter is then taken to the field where a gel
standard is again analyzed prior to wastewater sample analyses. If the annual 5-point curve option is
being performed, then only one check standard at a concentration near the mid-point of the 5-point curve
is required each day of analysis. The use of gel standards by Non-Field labs is permitted when the
analyses are performed in a field setting. For this application, a field setting is defined as: A location off
the primary facility grounds and/or at such a distance that sample collection and analysis could not be
achieved at the primary facility within the parameter holding time (i.e., 15 minutes).
Comment: Duplicates are not required for in situ/on-site analyses.
Fecal Coliform – Standard Methods, 9222 D – 1997
A. Finding: Culture medium used for the Fecal Coliform MF method is not being tested prior to use.
Requirement: When a new lot of culture medium, pads, or membrane filters is to be used, a
comparison of the current lot in use (reference lot) against the new lot (test lot), must be made. As
a minimum, make single analyses on five positive samples. Ref: NC WW/GW LC Policy based on
Procedure for Testing Consumable Materials for Biological Testing.
Comment: Testing was being performed on filters.

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 NPDES Permit # NC0039527 for June, 2012. The following errors were noted:
Date Parameter Location Value on Benchsheet Value on DMR
06/12/12 Fecal Coliform Effluent 1 e cfu/100 1 #/100
06/19/12 Fecal Coliform Effluent 2 e cfu/100 2 #/100
06/26/12 Fecal Coliform Effluent 1 e cfu/100 1 #/100
“e” in the above chart means “estimated”.
“#” in the above chart means “colony counts”.
Situations where 100 ml of sample were analyzed for Fecal Coliform and the result was 1cfu/100ml
would not have required that the result be qualified as “estimated”. The lab stated in an email on
11/6/12 that future reporting of Fecal Coliform results would follow the Fecal Coliform Reporting
document dated 03/25/03 (see attached).
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 finding 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.
