This map shows EPA 303(d) waterbodies and streams. These data are provided by Bureau of Land Management (BLM) "as is" and may contain errors or omissions. The User assumes the entire risk associated with its use of these data and bears all responsibility in determining whether these data are fit for the User's intended use. These data may not have the accuracy, resolution, completeness, timeliness, or other characteristics appropriate for applications that potential users of the data may contemplate. The User is encouraged to carefully consider the content of the metadata file associated with these data. The BLM should be cited as the data source in any products derived from these data.
These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. This coverage contains land-cover information for all of Ohio and portions of Indiana, Michigan, Kentucky, West Virginia, Pennsylvania, and New York. This dataset was derived from the U.S. Geological Survey's National Land Cover Dataset (NLCD). NLCD raster grids were downloaded from the USGS EROS Data Center web server at http://landcover.usgs.gov/natllandcover.html, by state. These grids were then reprojected, mosaiced and clipped...
This tabular data set represents the percent of United States Environmental protection Agency's (U.S. EPA) Level 3 Regions compiled for two spatial components of the NHDPlus version 2 data suite (NHDPlusv2) for the conterminous United States; 1) individual reach catchments and 2) reach catchments accumulated upstream through the river network. This dataset can be linked to the NHDPlus version 2 data suite by the unique identifier COMID. The source data is the "Level III and IV Ecoregions of the Continental United States" produced by the U.S. EPA (2013). Units are percent. The level 3 ecoregions are an 85-class classification scheme of areas of general similarity in ecosystems and in the type, quality, and quantity...
The North East 2nd Street Superfund site in Happy, Texas, overlies a groundwater plume of primarily carbon tetrachloride (CT) that is contained within an upper transmissive zone (EA Engineering, Science, and Technology, Inc., 2019) of the Ogallala aquifer. The Ogallala aquifer is contained at the site in Tertiary-age sediments of the Ogallala Formation, which are described by Nordstrom and Fallin (1989, p.10) as "tan, yellow, and reddish-brown, silty to coarse-grained sand mixed or alternating with yellow to red silty clay and variable sized gravel." The plume originated from the application of fire-retardant chemicals to the ground surface during the extinguishing of a fire at a grain storage elevator in 1962....

This dataset depicts the distribution and summary toxic chemical release information for petroleum refineries within the United States. This dataset is based on data retrieved from the Environmental Protection Agency's (EPA) Toxics Release Inventory (TRI) database on 4/2008 by the Conservation Biology Institute (CBI). These data are based on the 2006 EPA reporting year, and do not reflect cumulative toxic release quantities for previous years. Using a series of queries against the TRI database, we compiled information about the locations of petroleum refining facilities and quantities of toxic chemical release by various categories. From this information, we calculated the total toxic chemical release, and split...
This dataset was derived from the U.S. Environmental Protection Agency's Emissions & Generation Resource Integrated Database (eGRID2012 Version 1.0). The points in this dataset represent the location of all U.S. electricity generating plants that provide power to the electric grid and report data to the U.S. government within the DRECP study area. In addition to geographic location, this dataset also includes information on the environmental characteristics of almost all electric power generated among power plants within the DRECP study area. http://www.epa.gov/cleanenergy/energy-resources/egrid/index.html These data were downloaded in MS EXCEL format and converted to a feature class in a geodatabase. The data...
The 303(d) Listed Impaired Waters program system provides impaired water data and impaired water features reflecting river segments, lakes, and estuaries designated under Section 303(d) of the Clean Water Act. Each State will establish Total Maximum Daily Loads (TMDLs) for these waters. Note the CWA Section 303(d) list of impaired waters does not represent waters that are impaired but have an EPA-approved TMDL established, impaired waters for which other pollution control mechanisms are in place and expected to attain water quality standards, or waters impaired as a result of pollution and is not caused by a pollutant. Therefore, the "Impaired Waters" layers do not represent all impaired waters reported in a state's...

State of Utah's assessed lakes coverage (converted to 30m raster coverage) based on data created for the draft 2014 Integrated Report from Utah Division of Water Quality (DWQ) Feb, 2015. The Utah lakes depicted here were sampled in order to determine whether each water body should be categorized as impaired (under the 2014 draft report guidelines) based on EPA designations. These GIS data can be used to identify potentially impaired waters, based on statewide Assessment Unit (AU) polygons for Utah (USGS 5th and 6th hydrologic unit boundaries as developed by USGS in Salt Lake City, call Karen Hansen, 801-908-5038 for more info.)
ICIS-NPDES is an information management system maintained by the Office of Compliance to track permit compliance and enforcement status of facilities regulated by the National Pollutant Discharge Elimination System (NPDES) under the Clean Water Act (CWA). ICIS-NPDES is designed to support the NPDES program at the state, regional, and national levels.Active facilities are those currently in operation. Major/federally-reportable are facilities for which states must submit compliance and enforcement data to EPA. Under the Clean Water Act, a major facility is any NPDES facility or activity classified as such by the regional administrator, or in the case of approved state programs, the regional administrator in conjunction...
The NHDPlus Version 1.0 is an integrated suite of application-ready geospatial data sets that incorporate many of the best features of the National Hydrography Dataset (NHD) and the National Elevation Dataset (NED). The NHDPlus includes a stream network (based on the 1:100,000-scale NHD), improved networking, naming, and "value-added attributes" (VAA's). NHDPlus also includes elevation-derived catchments (drainage areas) produced using a drainage enforcement technique first broadly applied in New England, and thus dubbed "The New-England Method". This technique involves "burning-in" the 1:100,000-scale NHD and when available building "walls" using the national Watershed Boundary Dataset (WBD). The resulting modified...

Point coverage of Great Lakes, USA Areas of Concern (AOC's). AOC's are areas where serious impairment of beneficial uses of water or biota (swimming, fishing, drinking, navigation, etc.) is known to exist, or where environmental quality criteria are exceeded to the point that such impairment is likely.
River segments, lakes, and estuaries designated under Section 303(d) of the Clean Water Act. Each State will establish Total Maximum Daily Loads (TMDLs) for these waters. Most Current 303(d) Waterbodies coded onto NHD Waterbody reaches (region.rch) to create Waterbody Shapefiles.
