TYPE OF INSPECTION: Field Maintenance

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 neat and equipment was well maintained. The facility has all the equipment necessary
to perform the analyses on the laboratory’s certificate attachment. Records were maintained and well
organized. However, some quality control procedures need to be implemented.
The laboratory was given a packet containing the Technical Assistance Documents and quality control
requirements for all field parameters during the inspection.
III. FINDINGS, REQUIREMENTS, COMMENTS AND RECOMMENDATIONS:
Documentation
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 buffers, lots of pre -made standards
are included in this requirement. Ref: Quality Assurance Policies for Field Laboratories.

Recommendation: It is recommended that the laboratory use the attached laboratory
benchsheet as an example. It includes spaces to record the traceability information. An
example benchsheet was left by the inspector during the audit; however, that example did not
include spaces to record traceability information for chemicals, reagents, standards and
consumables. Attached is an example benchsheet that includes all of the necessary traceability
documentation. (See Attachment).
B. Finding: The laboratory is not verifying the calibration of the repipettors.
Requirement: Mechanical volumetric liquid-dispensing devices (e.g., fixed and adjustable
auto-pipettors, bottle-top dispensers, etc.) must be calibrated at least every twelve months and
documented. Each liquid-dispensing device must meet the manufacturer’s statement of
accuracy. For variable volume devices used at more than one setting, check the accuracy at
the maximum, middle and minimum values. Testing at more than three volumes is optional.
When a device capable of variable settings is dedicated to dispense a single specific volume,
calibration is required at that setting only. Ref: Quality Assurance Policies for Field
Laboratories.
Settleable Solids – Standard Methods, 18th Edition, 2540 F
C. Finding: The laboratory is not documenting the 45 minute stir time.
Requirement: The 45 minute stir time must be documented whenever sample analysis is
performed. Ref: Technical Assistance for Field Analysis of Settleable Solids.
pH – Standard Methods, 18th Edition, 4500 H+ B
D. Finding: The laboratory is not documenting the time the instrument is calibrated.
Requirement: The time the instrument is calibrated must be documented whenever sample
analysis is performed. Ref: Technical Assistance for Field Analysis of pH.
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 Bunn (NPDES permit #NC0042269); Cottonwood (NPDES permit
#NC0065706); Hill Forest Rest Home (NPDES permit #NC0038849); Indian Creek (NPDES permit
#NC0060771); Pope Industrial (NPDES permit #NC0060526); River Mill Condos (NPDES permit
#NC0056278); River Place (NPDES permit #NC00011376); and Town of Spring Hope (NPDES permit
#NC0020061) for March, May and July, 2010. The following errors were noted:

No Value 0.07 mg/L
The analyst suspects that the Ammonia Nitrogen data was accidentally recorded as the Total
Phosphorous value. No Total Phosphorous samples were required to be analyzed and reported on this
specific day.
In order to avoid questions of legality or a possible monitoring frequency violation, it is recommended
that the laboratory contact the appropriate Regional Office for guidance as to whether additional
corrective actions need to be taken or 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 findings and implementing the recommendation will help this lab to produce
quality data and meet certification requirements. The inspector would like to thank the staff for its
assistance in the inspection and data review process. Please respond to all findings.
