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. Records were filed in an orderly manner and readily available
for review.

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.

Contracted analyses are performed by 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:

Traceability

A. Finding: The laboratory needs to increase the documentation of purchased materials and
reagents (i.e., pH buffers).

Requirement: 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. A system (e.g., traceable identifiers) must be in place that links
standard/reagent preparation information to analytical batches in which the solutions are used.
Documentation of solution preparation must include the analyst’s initials, date of preparation, the
volume or weight of standard(s) used, the solvent and final volume of the solution. This information
as well as the vendor and/or manufacturer, lot number, and expiration date must be retained for
chemicals, reagents, standards and consumables used for a period of five years. Consumable
materials such as pH buffers and lots of pre-made standards are included in this requirement. Ref:
Quality Assurance Policies for Field Laboratories.

IV. 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 Shields
MHP (NPDES permit #NC0055271) and B. Everett Jordan WWTP (NPDES permit #NC0042528) for July,
August and September, 2012. No transcription errors were detected. It appears the laboratory is doing a
good job of accurately transcribing data.

V. CONCLUSIONS:

Correcting the above-cited finding 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.
