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.
GENERAL COMMENTS:
The laboratory was clean and equipment appeared well maintained. Records were well organized. This
facility is operating a pre-treatment program under the administration of the City of Reidsville.
The laboratory was given a packet containing North Carolina Laboratory Certification quality control
requirements and approved procedures during the inspection.
Contracted analyses are performed by Pace Analytical Services, Inc. - Huntersville (Certification #12) and
Meritech, Inc. (Certification #165).
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.
pH — Standard Methods, 18th Edition, 4500 H+ B
B. Finding: The pH meter is not equipped with Automatic Temperature Compensation (ATC).
Requirement: The laboratory must have a pH meter consisting of potentiometer, a glass
electrode, a reference electrode or combination electrode and a temperature compensating
device. Ref: Standard Methods, H B-2000, 4500 H + B. (2) (a). A copy of the manufacturer's
specifications showing that the meter contains a temperature compensating device,
documentation showing the purchase of an ATC probe compatible to the meter currently
used, or a new meter equipped with a temperature compensating device, must be
submitted with the response to this report.
Requirement: Each facility must have glassware, chemicals, supplies, equipment, and a source
of distilled or de -ionized water that will meet the minimum criteria of the approved methodologies.
Ref: 15A NCAC 02H .0805 (g) (4).
Temperature — Standard Methods, 18th Edition, 2550 B
C. Finding: The laboratory is checking the temperature on the mercury glass thermometer semi-
annually against a National Institute of Standards and Technology (NIST) traceable
thermometer, but is not posting the corrections on the thermometer.
Requirement: The temperature correction (even if it is zero) must be posted on the
temperature sensing device, as well as in hard copy format (to be retained for 5 years). Ref:
Approved Procedure for Field Analysis of Temperature.
The paper trail consisted of comparing field testing records and contract lab reports to semi-annual and
daily Industrial User Pretreatment Permit (IUP) reports submitted to the City of Reidsville Pretreatment
Division. Data were reviewed for Dystar LP (NPDES permit #NCG060000) City of Reidsville (Industrial
User Pretreatment Permit #0007) for March and November, 2011 and March, April, May and June,
2012. The following transcription error was detected:
The contract laboratory is reporting Oil & Grease data as "ND" (which stands for non -detect), but lists
the reporting limit as <5 mg/L. The laboratory is interpreting the ND as "0", thus Oil & Grease values
are being reported on the IUP as "0" when they should be reporting these "ND" values as "<5 mg/L".
V. CONCLUSIONS:
Correcting the above -cited findings will help this la
requirements. The inspector would like to thank the
data review process. Please respond to all findings.
