Parent Layer: Integrated Report (IR)

Name: IR - Zinc - Streams

Display Field: Waterbody_Name

Type: Feature Layer

Geometry Type: esriGeometryPolyline

Description: This layer provides the linework for all flowing non-tidal waters zinc assessments from the Combined 2020-2022 Integrated Report. Assessment information includes all assessments captured within Maryland's Combined 2020-2022 Integrated Report and are generally displayed according to Categories: impaired and require a TMDL (Category 5), impaired and have a TMDL approved by the Environmental Protection Agency (EPA) (Category 4a), impaired but have exemptions from needing a TMDL (Categories 4b-4c), insufficient data is available to determine if water is meeting all standards (Category 3), are meeting some standards (Category 2), and waters that are meeting all standards (Category 1).

Definition Expression: N/A

Copyright Text: The Maryland Department of the Environment (MDE) acknowledges the U.S. Geological Survey (USGS) which created the National Hydrography Dataset (NHD). The NHD serves as the stream linework for this file and was used to geospatially describe Maryland's water quality assessments for a variety of pollutants. The Maryland Department of the Environment linked the Integrated Report assessment information to the NHD and then preserved this pollutant-specific layer.
