One of the requirements of your North Carolina laboratory certification is analysis of a Performance Evaluation
(PE) sample obtained from an accredited vendor. To date we have not received any PE results for your
facility. You are reminded that an acceptable performance evaluation result must be obtained for all certified
parameters which are available from the accredited vendors. Failure to submit a passing PE result by December
31, 2005. will be considered a first miss. Failure to analyze and submit an acceptable follow up sample result
within 60 days after a failure notification or producing a second successive unacceptable result may result in
decertification for that parameter.
Please contact us at 919-733-3908 if you have questions or need additional information.
Sincerely,
Norman L. Good
