Environmental and Geographic Analysis Database (EGAD) - EGAD (formerly known as the Environmental and Groundwater Analysis Database) is an electronic repository for a wide variety of environmental data. It includes soil, sediment, air and water quality data, as well as spatial data from potential and actual sources of contamination to Maine’s groundwater. It also contains biological and surface water sampling site types, which enables DEP staff to more readily assess the water quality of Maine’s lakes, streams and rivers, and to determine the Class status and non-attainment status of various waterbodies.
