   dcterms:description "This EnviroAtlas dataset contains the total length in kilometers of streams, coastlines, canals, and other linear hydrographic features from the National Hydrography Dataset (NHD) per 12-digit Hydrologic Unit (HUC); the total length of features that have listed 303(d) impairments for biota, metals, nutrients, fish, habitat, temperature, pollution, or other impairments; and the ratio of stream length to 12-digit HUC area, or stream density. This dataset was produced by the US EPA to support research and online mapping activities related to EnviroAtlas. EnviroAtlas (https://www.epa.gov/enviroatlas) allows the user to interact with a web-based, easy-to-use, mapping application to view and analyze multiple ecosystem services for the contiguous United States. The dataset is available as downloadable data (https://edg.epa.gov/data/Public/ORD/EnviroAtlas) or as an EnviroAtlas map service. Additional descriptive information about each attribute in this dataset can be found in its associated EnviroAtlas Fact Sheet (https://www.epa.gov/enviroatlas/enviroatlas-fact-sheets)."^^xsd:string;
