SUBJECT: Laboratory Certification Maintenance Inspection
Dear Mr. Frye:
7 2003
Enclosed is a report for the inspection performed on September 30, 2003 by Mr.
Frederick L. Bone and Ms. Edith Henderson. Where deficiencies are cited in this report,
a response is required as well as for all lettered comments and/or recommendations.
Within thirty days of receipt, please supply this office with a written item for item description
of how these deficiencies, comments and/or recommendations were corrected. If the
deficiencies cited in the enclosed report are not corrected, enforcement actions will be
recommended. For certification maintenance, your laboratory must continue to carry out
the requirements set forth in 15A NCAC for 2H .0800.
Copies of the checklists completed during the inspection may be requested from this
office. Thank you for your cooperation during the inspection. If you wish to obtain an
electronic copy of this report by email, or if you have questions or need additional
information please contact us at 919-733-3908.
Sincerely,
aAria

On -Site Inspection Report
LABORATORY NAME: Moore Co. Water Pollution
ADDRESS:
P.O. Box 813
1060 Addor Road
Pinebluff, NC 28373
CERTIFICATE NO: 134
DATE OF INSPECTION: September 30, 2003
TYPE OF INSPECTION: Maintenance
EVALUATOR: Frederick L. Bone and Edith Henderson
LOCAL PERSON(S) CONTACTED: Stephanie Bigsby
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 is spacious and well equipped. All facilities and equipment are well maintained.
Records are well kept and most data looked good. Some further quality control procedures need
to be implemented.
III. DEFICIENCIES, RECOMMENDATIONS, REQUIREMENTS, AND COMMENTS:
General:
A. COMMENT: The laboratory frequently uses "pass or fail" and acceptable "yes or no" to
indicate that Residual Chlorine preservation checks have been performed on various types of
analyses.
RECOMMENDATION: It is strongly recommended that the laboratory give the definition for
what is acceptable or what is passing when it comes to preservation checks on each
laboratory benchsheet. Each benchsheet should clearly identify the lower reporting limit used
to verify proper preservation. An actual number obtained listed as a Tess than value provides
better clarity as to what level the preservation was documented to. For most analysis chlorine
must be. removed to < 0.5 mg/L.
Ammonia:
1. DEFICIENCY: The laboratory is not distilling any samples prior to analysis and has no
current comparative data on file.

Page 2
Note: The last ammonia distillation comparative study was performed in August 2002.
REQUIREMENT: To analyze samples without distillation, shall accumulate comparative data
by analyzing at least six samples distilled and undistilled, but at least two samples from all
waste types. Analyze one sample distilled and undistilled yearly from all waste types.
Additional samples must be analyzed comparatively if the above sample results do not
indicate approximately the same values for distilled and undistilled samples. Ref: Federal
Register, January 31, 1994; 40 CFR 136; Footnote 6.
B. COMMENT: The laboratory uses multiple pH meters to obtain reportable pH
measurements. The laboratory calibrates each meter in a separate logbook from where the
data is recorded. The laboratory does not indicate which pH meter is used for the data that is
reported.
RECOMMENDATION: It is strongly recommended that the laboratory clearly indicate which
pH meter is used to report data so that the calibration of the pH meter used can be verified.
Conductivity:
2. DEFICIENCY: The lab is analyzing standards at 717.5 and 73.9 pmhos/cm, but the sample
values are sometimes below 73.9 pmhos/cm. The laboratory must analyze at least three
conductivity standards daily that bracket expected analytical range.
REQUIREMENT: For analytical procedures requiring a series of standards, the
concentrations of these standards must bracket the concentration of the samples analyzed,
and one of the standards must have a concentration equal to the laboratory's lower reporting
limit. Ref: 15A NCAC 2H .8005 (a) 97) (I).
IV. PAPER TRAIL INVESTIGATION:
This consisted of comparing data reported on DMR's submitted to this Division with the values
obtained on laboratory bench worksheets. Data reviewed for the months of January, March, and
July 2003 indicated no problems in proper data reporting.
V. CONCLUSIONS:
Correcting the above deficiencies and comments and implementing the recommendations will
help the laboratory to produce quality data and meet certification requirements.
Please respond to all Deficiencies and lettered Comments cited in this report.
