This downloadable package contains the following layers: EPA facility points, EPA region boundary polygons and EPA region boundary polygons extended to the 200nm Exclusive Economic Zone (EEZ). Included in this package are a file geodatabase (v. 10.0), Esri ArcMap map document (v. 10.0) and XML files for this record and the layer level metadata. This dataset was produced by EPA Office of Environmental Information (OEI).
Drinking Water; water quality and public water system inventory database for use by small regulatory programs such as regional tribal drinking water programs, the Navajo Nation, or American Samoa.
An enhancement tool for the Office of Enforcement and Compliance Assurance (OECA) Enforcement Targeting Tool (ETT) list, allowing drinking water programs to annotate and track additional information about Public Water Systems (PWS) found on the ETT list. Tool is used to inform enforcement action targeting by States, Regions, Territories, Tribes and EPA.
2009 water sample results of unregulated livestock water sources on the Navajo Nation. These unregulated water sources were sampled as part of EPA's work on the multi-agency Five-Year Plan to address uranium contamination on the Navajo Nation.
Used by all EPA Regions to conglomerate data from several existing data sources: Safe Drinking Water Information System (SDWIS), Office of Enforcement and Compliance Assurance (OECA) Enforcement Targeting Tool (ETT) list, Indian Health Service (IHS) Project Data System (PDS), and EPA's Integrated Grants Managment System (IGMS). These data are then augmented by Region entered fields to round out the information for funding expenditures for several EPA programs that benefit Tribes. Those are the Public Water Supply Supervision (PWSS), State Revolving Fund Drinking Water Tribal Set Aside (SRF DWTSA), State Revolving Fund Clean Water Tribal Set Aside (SRF EWTSA), as well as the American Recovery and Reinvestment Act (ARRA) drinking water and clean water programs.
2010 water sample results of unregulated livestock water sources near the NECR uranium mine. These unregulated water sources were sampled as part of EPA's work on the multi-agency Five-Year Plan to address uranium contamination on the Navajo Nation.
This EnviroAtlas dataset is a digital hydrologic unit (HUC) boundary layer to the Subwatershed (12-digit) 6th level for Puerto Rico, based on the May 2016 NHDPlus V2.1 WBD (Watershed Boundary Dataset) Snapshot for Puerto Rico & U.S. Virgin Islands. Information on the percent land area has been added, and HUCs for Puerto Rico and the Virgin Islands have been split into two separate files. The location of one HUC (a small island) has been adjusted to align with aerial imagery and GAP (Gap Analysis Program) land cover data. 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).
NHDPlus Reach Indexed points for EPA Facility Registry locations.
The Katrina Air Quality System (AQS) contains records specific to the Katrina/Rita Emergency Response and provides this data to the Environmapper application.
ToxCast is used as a cost-effective approach for efficiently prioritizing the toxicity testing of thousands of chemicals. It uses data from state-of-the-art high throughput screening (HTS) bioassay and builds computational models to forecast potential chemical toxicity in humans. ToxRefDB stores data related to ToxCast.
