Name: Nitrate violation index - Groundwater

Display Field: HUC_12

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: <a href = "https://edg.epa.gov/metadata/catalog/search/resource/details.page?uuid=%7B7c44dad0-98aa-45ee-8011-4e3d2332c5c7%7D">Full Metadata</a> This map represents the random forest probability of a nitrate violation for groundwater systems. Higher values indicate a higher probability of a risk of violation. A random forest model is an ensemble of many decision trees, with the probability indicating the proportion of trees predicting a violation. Based on violations occuring between 2013 and 2017.
