Maintenance Inspection
Dear Mr. Baxley:
Enclosed is a report for the inspection performed on January 28, 2014 by Nick Jones. Since the
finding(s) cited during the inspection were all corrected prior to the completion of the enclosed
report, a response is not required. The staff is commended for taking the initiative in correcting
the findings in such a timely manner. For certification maintenance, your laboratory must
continue to carry out the requirements set forth in 15A NCAC 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 electronic mail, or if you have questions or need additional information please
contact me at [phone].
Sincerely,
Gary Francies
Technical Assistance/Compliance Specialist

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.
II. GENERAL COMMENTS:
The laboratory was clean and well organized. The facility has all the equipment necessary to perform the
analyses. Laboratory personnel communicate well with sample collectors and coordinate sample
analyses effectively to manage workload and holding times.
Contracted analyses are performed by Meritech, Inc. (Certification #165).
Current quality assurance policies for Field Laboratories and approved procedures for the analysis of
the facility's currently certified parameters were provided at the time of the inspection.
III. FINDINGS, REQUIREMENTS, COMMENTS AND RECOMMENDATIONS
Quality Control
Comment: The laboratory needs to increase the documentation of purchased materials and reagents,
as well as documentation of standards and reagents prepared in the laboratory. The NC WW/GW LC
Quality Assurance Policies for Field Laboratories states: 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 analvst'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 aH buffers and lots of pre -made standards are included in this
requirement. Demonstration of acceptable corrective action (i.e., a standard/reagent preparation log)
was received by email on 1/30/2014. Notification of acceptable corrective action (i.e., a statement that

a traceability log which documents all consumables has been implemented) was received by e-mail on
1/30/2014. No further response is necessary for this finding.
PH — SM 4500 H+B-2000
Comment: The facility name and time of meter calibration are not documented on the benchsheet. The
North Carolina Administrative Code, 15A NCAC 2H .0805 (g) (2) states: A record of instrument calibration
where applicable, must be filed in an orderly manner so as to be readily available for inspection upon
request. The NC WW/GW LC Approved Procedure for Analysis of pH states: Document facility name and
meter calibration time. Demonstration of acceptable corrective action (i.e., a benchsheet documenting
the facility name and time of meter calibration) was received by email on 1/30/2014. No further
response is necessary for this finding.
Comment: The facility is reporting averaged pH results. The Directions for Completing Monthly
Discharge Monitoring Reports Policy, (II)(8) states: Please note no average is to be calculated for pH. .
Notification of acceptable corrective action (i.e., a statement that duplicates for pH will no longer be
analyzed and subsequently not averaged) was submitted by email on 2/5/2014. Analyzing pH samples in
duplicate is not a requirement. No further response is necessary for this finding.
Total Residual Chlorine — SM 4500 CI G-2000
Comment: It would be more economical, in terms of cost and time, if the facility used the factory
supplied stored calibration curve (stored under program #86), instead of each individual operator
creating their own user defined curves. An annual curve verification is still required, but only the
program #86 curve verified by one analyst would need to be performed. All of the operators could use
the stored curve (program #86) after it has been verified.
Prepare a curve (with your current standard) with the following concentrations: 20, —35, 50, 200 and
400 µg/L. Analyze them on program #86. Enter the true values and actual results into the Total
Residual Chlorine (TRC) spreadsheet you received from the inspector via email on January 30, 2014 to
determine if the curve and individual standard recoveries meet the acceptance criteria.
It would also be more economical, in terms of cost and time, if the lab implemented the use of gel
standards instead of liquid standards for the daily calibration verification, and switched from liquid
reagents to DPD powder pillows.
Comment: Neither the value nor acceptance criterion of the Reagent Blank are documented on the
benchsheet. The NC WW/GW LC Approved Procedure for Analysis of Total Residual Chlorine states:
Document the value obtained for the reagent blank, when prepared standards are used (verification of
<% the concentration of the lowest calibration standard). Demonstration of acceptable corrective action
(i.e., a benchsheet documenting the value obtained for the reagent blank) was received by email on
1/30/2014. No further response is necessary for this finding.
IV. PAPER TRAIL INVESTIGATION:
A paper trail was not performed.
V. CONCLUSIONS:
All findings noted during the inspection were adequately addressed prior to the completion of this
report. The inspector would like to thank the staff for its assistance during the inspection and data review
process. No response is required.
