This laboratory was, inspected to verify its compliance with the -requirements of 15A NCAC 2M .0800 for
the analysis of environmental samples.
This laboratory inspection was performed in conjunction with a laboratory requested technical assistance
visit. The laboratory received unacceptable results on their annual Proficiency Testing (PT) for Total
Residual Chlorine (TRC). Technical assistance for verifying the internal calibration curves of the old and
new meters was provided on October 5, 2010. The laboratory later analyzed known samples and was
unable to obtain acceptable results. Additional technical assistance was provided on October 28, 2010
once a new set of known samples from two separate vendors arrived. It was determined that a
combination of interference from the store bought water and the flow through cell (which is not used for
sample analysis) caused the low results. The use of deionized water provided by the inspector and not
using the flow through cell resulted in acceptable results on the known samples. Results from the PT
sample analyzed are still pending at this time.
The laboratory was clean and well organized. The facility has all the equipment necessary to perform the
analyses. Finding A is a new policy that has been implemented by our program since the last inspection.
FINDINGS, REQUIREMENTS, COMMENTS AND RECOMMENDATIONS:
General Laboratory
Comment: Previous PT samples were not analyzed in the same manner as samples. The flow through
cell was used for PT samples, but not for routine samples. The Quality Assurance Policies for Field
Laboratories states: The analysis of PT samples is designed to evaluate the entire process used to
routinely report environmental analytical results. Therefore, PT samples must be analyzed and"the
process documented in the same manner as environmental samples. The analyst stated, during the
inspection, that the flow through cell would no longer be used in the laboratory. No further response is
necessary for this finding.
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 and lots of pre -made
standards are included in this requirement. Ref: Quality Assurance Policies for Field
Laboratories.
V. PAPER TRAIL INVESTIGATION:
No paper trail performed.
V. CONCLUSIONS:
Correcting the above -cited finding will help this lab
requirements. The inspector would like to thank the
data review process. Please respond to all findings.
