Imposition of these regulations requires careful evaluation with respect to state laboratories and universities providing advisory and environmental research data to agencies such as VDH or DEQ.  In many instances contractual agreements are developed that specify QA/QC plans to address the kinds of data concerns covered in the NELAC protocols.  Adoption of these regulations will place an additional monetary burden on state laboraties/universities and lead to a complex and difficult to administer certification system. Consideration must be given to alternatives.
