ADDRESS: P.O. Box 130
Broadway, NC 27505

I. INTRODUCTION:

This laboratory was inspected 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 well organized and maintained according to
the appropriate retention schedule, however, some quality control procedures need to be implemented.
Proficiency testing samples have been analyzed for all certified parameters for the 2011 proficiency
testing calendar year and the graded results were 100% acceptable.

The laboratory was given a packet containing North Carolina Laboratory Certification quality control
requirements and policies during the inspection.

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, as well as documentation of standards and reagents prepared in the laboratory.

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 buff ers 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 laboratory benchsheets and contract lab reports to Discharge
Monitoring Reports (DMRs) submitted to the North Carolina Division of Water Quality. Data were
reviewed for the Town of Broadway WWTP (NPDES permit #NC0059242) for the following months:
June, July and August, 2011. The following errors were noted:

Date Parameter Location
Value on Benchsheet
*Contract Data
Value on DMR
7/5/11 Total Phosphorous Effluent *4.11 mg/L 1.81 mg/L
7/5/11 Total Kjeldahl Nitrogen Effluent *1.81 mg/L 4.11 mg/L

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 forwarded to the Regional Office.

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.
