The **Updated** Environmental Data Mapper

The Environmental Data Mapper (EDM), launched by DEQ in January 2021, is a modernized successor to DEQ's legacy public GIS mapping tool (VEGIS/WIMBY). As of October 2024, the EDM has been upgraded to utilize Esri's latest application-building platform, ArcGIS Experience Builder. This transition to a new JavaScript framework has enhanced both the appearance and functionality of the EDM. As DEQ's premier interactive geospatial mapping tool, the EDM is designed to provide citizens, stakeholders, permit holders, government agencies, and other interested parties with improved access, engagement, and visualization of DEQ's GIS datasets.

Virginia Brownfields Dashboard (Beta)

Brownfields are properties in which redevelopment or reuse is complicated by the presence of hazardous materials, pollution or contaminants. There are thousands of these sites across the Commonwealth, including over 100,000 acres of previously mined lands.  To promote the reuse of these properties and to meet the market demand for investment, DEQ collaborated with the Virginia Department of Energy to centralize existing information in this unique brownfields dashboard. The dashboard is in early/Beta release and DEQ welcomes feedback from stakeholders and the community. For more information on brownfields in Virginia, please visit the DEQ Brownfields page.
