  • Catalogue of Life - ITIS and Species 2000 Exit
    The Catalogue is published as two products: The Annual Checklist is published each year as a fixed edition. The Dynamic Checklist is real time access to the Species 2000 array of 26 online taxonomic databases, less extensive than the Annual Checklist.
  • EnviroMapper for Water
    A map-based query tool with access to Legacy and Modern STORET sampling stations. Using this tool, you can zoom in on any area of the United States, and examine the map for locations of streams, roads, political boundaries, and other features. You can add Legacy or Modern STORET water quality monitoring stations to the map, and select them for downloading data.
  • MyEnvironment
    MyEnvironment is a powerful map-based tool that provides a wide range of federal, state, and local information about environmental conditions and features in an area of your choice. This application is provided by U.S. EPA in partnership with federal, state and local government and other organizations.
  • The Exchange Network Browser Exit
    The Exchange Network Browser access the PRODUCTION Environment of the Exchange Network. This tool lets people retrieve data from environmental data providers who have published environmental and health data on the Exchange Network and registered their data with the Exchange Network Discovery Service. Seach using Map. Search using Environmental Interest. Browse ALL...

    The Exchange Network Browser (EN Browser), is adopted as a shared tool by the Exchange Network Leadership Council, allows people to discover environmental and health data across the country that are published from different State, Tribal and Federal Exchange Nodes.

  • Integration Test Tool - Node in the Exchange Network Exit
    This application provides the ability to test any Node in the Exchange Network, by triggering Network WSDL-compliant requests on that Node. If a Node passes a test with this tool, if is very likely, if not guaranteed, that the Node will be interoperable with other Network WSDL-compliant Nodes. This tool, which is intended to verify general compliance with the Functional Specification, focuses on interoperability among Nodes.

    In order to become compliant, Node developers must implement the Network WSDL found here The URL that is provided during initialization will be used as the end point address of the Node to be tested.
    In the menu pane, testers can choose to perform either interactive tests, automatic tests, or multi-step scenarios. Note that the tool is under construction, so some operations will be provided later.

Water Quality Assessment Tools

  • Data Quality and Assessment Management Tools
    Data Quality Assessment is used to assess the type, quantity, and quality of data in order to verify that the planning objectives, Quality Assurance Project Plan components, and sample collection procedures were satisfied and that the data are suitable for its intended purpose. This link provides the EPA's documentations and tools to assess the data quality.
  • Water Quality Assessment and ATTAINS
    The Assessment Total Maximum Daily Load (TMDL) Tracking and Implementation System (ATTAINS) provides information reported by the states to EPA about the conditions in their surface waters. This information is required every two years under Clean Water Act Sections 305(b) and 303(d).
  • National Aquatic Resource Surveys
    The U.S. Environmental Protection Agency, states, and tribes are conducting a series of national aquatic resource surveys. Often referred to as probability-based surveys, these studies report on core indicators of water condition using standardized field and lab methods.

    The surveys include a national quality assurance program and are designed to yield unbiased, statistically-representative estimates of the condition of the whole water resource (such as rivers and streams, lakes, ponds, and reservoirs, wetlands, etc).
    WATERS (Watershed Assessment, Tracking & Environmental ResultS) unites water quality information that was previously available only from several independent and unconnected databases.
  • Surf Your Watershed
    Locate Your Watershed and find Watershed Health Information about a place of interest. Watersheds are based on the Hydrologic Unit Code (HUC) scheme developed by the United States Geological Survey, and provide coverage of the continental United States only.
  • Nitrogen and Phosphorus Pollution Data Access Tool (NPDAT)
    The EPA Nitrogen and Phosphorus Pollution Data Access Tool (NPDAT) is a Web-based tool intended to help states develop effective strategies for reducing nitrogen and phosphorus pollution. The NPDAT consists of an introductory website, geospatial viewer, and data download tables.
    Data available on the NPDAT include:
    • Nitrogen and Phosphorus Loading information from U.S. Geological Survey SPARROW model
    • Water Quality Data and Information (National Aquatic Resource Surveys (NARS) Phosphorus/ Nitrogen Values data layers)
    • Setting Watershed Load Reduction Goals / Source Control Priorities.

EPA/STORET Partner Services

  • National Hydrography Dataset
    The National Hydrography Dataset is a geospatial database that interconnects and uniquely identifies the "reaches" that comprise the nation's surface water drainage system. It is based upon the content of the USGS DLG integrated with reach-related information from the EPA RF3.
  • Hydro Event Management Tools (see EPA Add-on Tools further down the page)
    The U.S. Environmental Protection Agency (EPA) has developed a supplemental set of indexing functions for the HEM, which are available through the HEM EPA Add-Ons toolbar. This toolbar allows users to create, edit and manage custom point, line and area events. The toolbar also includes functionality that was previously a part of the PC based Reach Indexing Tool (PC- RIT), such as:
    • Find Overlapping Waterbodies,
    • Extract from EPA Program Events,
    • and a post processing tool to aid in preparing events for submission to the EPA's Reach Address Database (RAD).
