Abstract

Considerable attention has been directed towards techniques and procedures which facilitate the high quality of field-collected ambient environmental data.

This study addresses the quality control methods used to assure data quality after the data have been recorded. The two major elements associated with the validation of much of Tennessee Valley Authority's (TVA's) environmental data are: (1) initial computer flagging of physically/chemically questionable and outlying data and (2) analyst review and feedback to field technicians to implement corrective actions. Examples of these procedures as applied to aerometric data will be discussed.

The benefits of this approach include timely feedback to the field technicians to resolve potential problems with a monitoring system and assignment of quality code ratings and precision and accuracy to all archived and reported data.
