Medical Service monitoring of environmental water quality as mandated by AFR 19-1 and AFR 19-7 will generate vast amounts of data. A computer data automation system is needed to convert these data into usable information for documenting present pollution levels, for determining the effectiveness of corrective measures, for appraising the character of unique Air Force waste discharges and for monitoring the effects of Air Force operations on the water environment. In this study, the magnitude of the data storage and retrieval requirement and several possible computer systems for handling it were evaluated. The results of this study demonstrate that the Air Force should develop its own water quality data storage and retrieval computer program using a data identification system that is compatible with the EPA STORET system. Inclusion of the water sample analysis data in a Master Data Repository will first require modifications in the current site identification and sample submission procedures of AFR 19-7.
