On-Site Inspection Report
LABORATORY NAME: Cary – Apex Water Treatment Facility
NPDES PERMIT #: NC0081591
ADDRESS: P.O. Box 8005
Cary, NC 27512-8005
CERTIFICATE #: 5456
DATE OF INSPECTION: March 1, 2011
TYPE OF INSPECTION: Field Maintenance
AUDITOR(S): Jeffrey R. Adams
LOCAL PERSON(S) CONTACTED: Penny Rosser
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. Records were maintained and well
organized. The laboratory appears to be doing a good job in implementing North Carolina
Wastewater/Groundwater Laboratory Certification policies.
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:
Conductivity – Standard Methods, 18th Edition, 2510 B
Comment: The internal Automatic Temperature Compensator (ATC) is not verified on an annual
basis. The Technical Assistance for Field Analysis of Conductivity states: The ATC must be verified
annually (i.e., every twelve months) and the process documented. The ATC must be verified by analyzing a
standard at 25 °C (the temperature that conductivity values are compensated to) and a temperature(s) that
brackets the temperature ranges of the samples to be analyzed. This may require the analysis of a third
temperature reading that is > 25 °C. This finding has been corrected since the inspection. No further
response is necessary for this finding.
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 Cary – Apex Water Treatment Facility (NPDES permit #NC0081591) for the following
months:, October, November, and December, 2010. No transcription errors were detected. It appears
the laboratory is doing a good job of accurately transcribing data.
