This is a reference dataset for the Virginia Water Quality Standards for the tidal waters, represented as polygons, within the Virginia state boundary. See section 9VAC-25-260 of the Virginia Administrative Code for specific standards descriptions.

This report analyzed all DEQ stations with Total Phosphorus (TP) and Total Nitrogen (TN) samples taken from 2010 to 2020. Median values and number of samples the statistic was based on (n) are presented in the table below. 

The Resource Conservation and Recovery Act Information System (RCRAInfo) is EPA’s comprehensive information system in support of the Resource Conservation and Recovery Act (RCRA) of 1976 and the Hazardous and Solid Waste Amendments (HSWA) of 1984. It tracks many types of information about generators, transporters, treaters, storers, and disposers of hazardous waste.

This is a reference dataset for the Virginia Water Quality Standards for all free-flowing, freshwater streams, rivers and flowpaths designated as stockable or natural trout waters within the Virginia state boundary. See section 9VAC-25-260 of the Virginia Administrative Code for specific standards descriptions.

Locations of citizen properties with an extended setback from their property line and/or home.

Polygon feature class outlining the major river basin watershed areas within Virginia.

This dataset represents the geospatial extent as polygons and the corresponding attribution for census block groups that meet the first half of the definition of Communities of Color according to the Virginia 2020 Environmental Justice Act, or the former part in the excerpt provided below:
“Community of Color” definition: “’Community of color’ means any geographically distinct area where the population of color, expressed as a percentage of the total population of such area, is higher than the population of color in the Commonwealth expressed as a percentage of the total population of the Commonwealth. However, if a community of color is composed primarily of one of the groups listed in the definition of "population of color," the percentage population of such group in the Commonwealth shall be used instead of the percentage population of color in the Commonwealth.

The referenced “population of color” definition is also provided below:
“Population of Color” definition: “’Population of color’ means a population of individuals who identify as belonging to one or more of the following groups: Black, African American, Asian, Pacific Islander, Native American, other non-white race, mixed race, Hispanic, Latino, or linguistically isolated.”

Polygon layer representing all watershed Boundaries for the Implementation Watersheds, including Approved, In Progress and Completed Implementation Areas.

The Virginia Water Protection Program (VWP) regulates activities in all surface waters which includes wetlands, streams, and open water. A permit (general permit coverage or individual permit) may be required in accordance with program regulations and State Water Control Law. This layer represents the project location of both active and historic VWP General Permit Coverage (GP) issued across the state. The General Permit Tracking number, name, and regional office are among several attributes in this layer. The attribute data is pulled from DEQ's Comprehensive Environmental Data System (CEDS). The GIS data layers and maps produced by the Virginia Department of Environmental Quality (DEQ) are provided as a public resource. The Virginia Department of Environmental Quality has attempted to ensure the accuracy and completeness of the data. DEQ makes or extends no warranties of any type, expressed or implied, including but not limited to: appropriateness of use, accuracy, or completeness of data.
DEQ does not guarantee the GIS data provided is complete or current because the information contained in these data may change over time. These data and related maps are not legal documents and should not be construed or used as such. It is encouraged that these data are obtained from a DEQ resource and not through other sources which may lead to changed or outdated data. While using DEQ GIS data, the use and modification of such data is done at the risk of the user, and where DEQ holds no liability of any nature resulting from the use or correctness of this data.
Pursuant to Section 54.1-402, paragraph C of the Code of Virginia, this data may not be used for purposes listed in said paragraph C, since the data was not created, nor is it maintained under the supervision of a licensed land surveyor.

All reservoirs and lakes identified in the 2016 Virginia 305(b)/303(d) Water Quality Assessment. Line work and attributes should not be altered except by the developer (DEQ). This dataset constitutes the United States Environmental Protection Agency (EPA) approved digital version of the assessment hydrology for Virginia. Attributes assigned to each water segment are based on attributes associated with the ID305B (assessment unit ID) entered in the statewide water quality assessment database. QA/QC checks are performed on the database prior to linking attributes to the GIS data, however errors may still occur. Please direct any questions about attribute accuracy to the Data Distributor. The geospatial product is maintained and updated by VA DEQ each assessment cycle (biennially) using the most current NHD product where revisions were made to Virginia waters, the most recent aerial photography provided by the Virginia Geographic Information Network (VGIN), and by freehand digitizing where necessary. Metadata is provided in the data Fact Sheet which contains contact information, process steps, attribute descriptions, and distribution information.
