Laboratory Certification (NC WW/GW LC) program to verify its compliance with the requiremen
of 15A NCAC 2H •:i'• for the analysis of •, samples.
The laboratory was clean and well organized. The facility has all the equipment necessary tv:
perform the analyses. Laboratory personnel communicate well with sample collectors and
coordinate sample analyses effectivelyto manage workloadand holding

inspection.
Comment: The laboratory needs to increase the documentation of purchased materials a
reagents, as well as documentation of standards and reagents prepared in the laboratory. T
