The article describes the application of quality assurance (QA) principles to two programs supporting EPA's Environmental Assessment Data System (EADS). The ultimate objective of any measurement program is the creation of data that is processed to provide information. The development of information (e.g., trends, parameter estimates) from data is a process that may be as difficult as the data production, if not more so. Application of QA principles to this interpretive phase of information production includes: (1) data acquisition (human/machine interface), (2) verification (range- and relational-checking), (3) data processing (transfer, transformations, and reduction), and (4) presentation of results (comparability, ease of interpretation).
