Certification maintenance, your laboratory must continue to carry out the requirements set forth in 15A
NCAC 2H .0800.
A copy of the laboratory's Certified Parameter List at the time of the audit is attached. This list will reflect
any changes made during the audit. Copies of the checklists completed during the inspection may be

LABORATORY NAME: Pace Analytical Services LLC —Asheville NC
ADDRESS: 2225 Riverside Drive
Asheville, NC 28804
CERTIFICATE : 40
DATE OF INSPECTION: November 28, 2018
TYPE OF INSPECTION: Commercial Maintenance Abbreviated
AUDITOR(S): Jason Smith
LOCAL PERSON(S) CONTACTED: Barry Johnson and Eric Setzer
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 compliance monitoring samples.
II. GENERAL COMMENTS:
This was an abbreviated audit performed in conjunction with technical assistance requested by
the laboratory. The laboratory requested technical assistance to discuss troubleshooting
persistent unacceptable BOD blank results (>0.20 mg/L) which have occurred over the past few
months. Kathy Jimison, the laboratory analyst at the Asheville Regional Office of the NC Division
of Water Resources, also attended to provide assistance.
All required Proficiency Testing (PT) Samples have been analyzed and the laboratory has fulfilled
its PT requirements for the 2018 PT Calendar Year.
The laboratory submitted their Quality Assurance (QA) and/or Standard Operating Procedures
(SOP) document(s) in advance of the inspection. These documents were reviewed and editorial
and substantive revision requirements and recommendations were made by this program
outside of this formal report process. Although subsequent revisions were not requested to be
submitted, they must be completed by December 31, 2019.
The laboratory is reminded that any time changes are made to laboratory procedures, the
laboratory must update the QA/SOP document(s) and inform relevant staff. Any changes made
in response to the pre -audit review or to Findings, Recommendations or Comments listed in this
report must be incorporated to insure the method is being performed as stated, references to
methods are accurate, and the QA and/or SOP document(s) is in agreement with each
approved practice, test, analysis, measurement, monitoring procedure or regulatory
requirement being used in the laboratory. In some instances, the laboratory may need to create
an SOP to document how new functions or policies will be implemented.

The laboratory is also reminded that SOPS are intended to describe procedures exactl as they
are to be performed. Use of the word "should" is not appropriate when describing requirements
(e.g., Quality Control (QC) frequency, acceptance criteria, etc.). Evaluate all SOPs for the proper
use of the word "should".
Requirements that reference 15A NCAC 2H .0805 (a) (7) (A), stating "All analytical data pertinent
to each certified analysis must be filed in an orderly manner so as to be readily available for
inspection upon request", are intended to be a requirement to document information pertinent to
reconstructing final results and demonstrating method compliance. Use of this requirement is not
intended to imply that existing records are not adequately maintained unless the Finding speaks
directly to that.
- - • -III III,�. •
Documentation
Comment: The laboratory analyzes samples manually as well as with a Skalar automated
analyzer.
Recommendation: It is recommended that the laboratory maintain detailed notes about the effect
of procedural changes as part of the troubleshooting process. This will help identify which
combination of changes produces the best results.
A. Finding: Documentation for manual analyses does not demonstrate that the initial
Dissolved Oxygen (DO) is measured within 30 minutes of sample preparation. This is
considered pertinent data. Cited previously on July 25, 2017.
Requirement: After preparing dilution, measure initial DO within 30 min. Ref: Standard
Methods, 5210 B-2011. (5) (g).
Requirement: All analytical data pertinent to each certified analysis must be filed in an
orderly manner so as to be readily available for inspection upon request. Ref: 15 NCAC
21-1.0805 (a) (7) (A).
Comment: The laboratory corrected this Finding for manual analysis on the printed
benchsheets in use at the time of the last inspection. Since then, they have started
entering the data into an Excel spreadsheet which does not include this information.
Recommendation: The automated analyzer measures the DO immediately after sample
preparation and this is documented in the SOP. It is recommended that a statement
indicating this be added to the automated analysis print out.
Recommendation: It is recommended that the SOP (Section 12.5.1.8) refer to the
specific section of the automated analyzer instruction manual that describes analysis of
DO immediately after the bottle is prepared.
IV. PAPER TRAIL INVESTIGATION:
No paper trail performed.

We are concerned that the correction for the previously cited Finding was not addressed when
the laboratory began using an electronic data entry system.
Laboratory Decertification Ref: 15A NCAC 2H .0807 (a) (1), (13) and (14):
A laboratory may be decertified for any or all parameters for up to one year for any or all of the
following infractions:
(1) Failing to maintain the facilities, or records, or personnel, or equipment, or quality control
program as set forth in the application, and these Rules; or
(13) Failing to respond to requests for information by the date due; or
(14) Failing to comply with any other terms, conditions, or requirements of this Section or of a
Laboratory certification.
Correcting the above -cited Finding and implementing the Recommendation will help this
laboratory to produce quality data and meet Certification requirements. The inspector would like
to thank the staff for its assistance during the inspection and data review process. Please
respond to all Findings and include supporting documentation and implementation
dates for each corrective action.
