Environmental Data Management: Storage, Handling and Retrieval

Environmental data management for any agency can be a daunting task given the large number of sample sites generally needed, and the wide variety of parameters for which analysis may be required. As a result, it is imperative that a computerized system be developed which facilitates rapid storage; efficient, accurate handling; and easy retrieval of a large volume of data. Environmental data management systems currently used by a variety of State and Federal agencies are briefly described to provide an overview of such systems. One system, developed by the Louisiana Department of Environmental Quality (LDEQ), Office of Water Resources, is described in detail. The LDEQ system provides for both regularly occurring water quality monitoring data, as well as special project data as required. While this system was designed specifically for water quality data, it may be easily adapted by other agencies which utilize a wide variety of environmental data.
