EPA Fish Consumption Advisories Website Fish are a lean, low-calorie source of protein. However, some fish may contain chemicals that could pose health risks. When contaminant levels are unsafe, consumption advisories may recommend that people limit or avoid eating certain species of fish caught in certain places. Every year since 1993, the EPA has made available to the public a compendium of information on locally issued fish advisories and safe eating guidelines. This information is provided to EPA by states, U.S. territories, Indian tribes, and local governments who issue fish consumption advisories and safe eating guidelines to inform people about the recommended level of consumption for fish caught in local waters. Welcome to the EPA's Fish Consumption Advisory website. This website is divided into two main areas: a General Advisory Information area and a Technical Advisory Information area.

EPA's Energy Portal Energy use is a part of everyone's daily routine. However, the generation and use of energy can affect the environment. Our regulatory and voluntary programs foster more responsible production and use of energy resources. This Web site enables you to learn more about important energy topics and locate information about our energy programs. EPA Energy and Utilities 2012-09-18 11:50:53
EPA Water Services - Event Indexing Service The WATERS Web and Database services provide open interfaces to complex analyses. These services make extensive use of the NHD and referenced program data in the RAD, and also integrate other WATERS program data. Designed as loosely coupled modular units, the services are developed in a common architecture. The WATERS (Watershed Assessment, Tracking & Environmental ResultS) indexing engine allows applications to programmatically index features to the medium resolution National Hydrography Dataset and to create RAD (Reach Address Database)-ready event records.

EPA Water Services - Name Service The WATERS Web and Database services provide open interfaces to complex analyses. These services make extensive use of the NHD and referenced program data in the RAD, and also integrate other WATERS program data. Designed as loosely coupled modular units, the services are developed in a common architecture. Advanced query function to find U.S. Geological Survey GNIS (Geographic Names Information System) water feature names and provide general location information for National Hydrography Dataset features.

EPA Water Services - Navigation Delineation Service The WATERS Web and Database services provide open interfaces to complex analyses. These services make extensive use of the NHD and referenced program data in the RAD, and also integrate other WATERS program data. Designed as loosely coupled modular units, the services are developed in a common architecture. The Navigation Delineation service is a service that builds upon the Navigation Service to provide an areal representation of the navigation process by linking navigated flowlines to associated areal geographies. In most cases the primary areal feature associated with NHD flowlines are the NHDPlus catchments. However the service is designed to be expanded in future versions to return results for other associated areal coverages such as Watershed Boundary Dataset (WBD) or Tiger Political layers.

EPA Water Services - Navigation Service The Navigation service is a subset component of the Upstream/Downstream service designed to provide standard stream network traversal. The traversal request may include a description of where, on the stream network, to begin the traversal, and a description of where or how to end the traversal. All Upstream/Downstream executions require a navigation type and at least one start point. All other input parameters are optional. EPA Geography and Environment 2012-09-24 12:44:10
EPA Water Services - Point Indexing Service The WATERS Web and Database services provide open interfaces to complex analyses. These services make extensive use of the NHD and referenced program data in the RAD, and also integrate other WATERS program data. Designed as loosely coupled modular units, the services are developed in a common architecture. The Point Indexing service is a subset component of the Event Indexing Service providing a simplified point indexing function for linking a point to the National Hydrography Dataset (NHD) via either a straightforward shortest distance snap or via raindrop indexing utilizing the NHDPlus flow direction grid. The service returns the point, information about the indexing action and NHD flowline information describing the nearest NHD hydrography. EPA Geography and Environment 2012-09-24 12:44:10
EPA Water Services - RAD Event Information Service The RAD (Reach Address Database) Event Information Service is intended to allow dynamic yet efficient query access to RAD events and associated information. While the RAD utilizes a single common data structure, differing programs provide differing usage models of RAD data. The RAD information service leverages these usage models to combine an efficient query with a simple output data object. The creation of data usage models is an ongoing process.

EPA Water Services - Results Queue Service The WATERS Web and Database services provide open interfaces to complex analyses. These services make extensive use of the NHD and referenced program data in the RAD, and also integrate other WATERS program data. Designed as loosely coupled modular units, the services are developed in a common architecture. The Results Queue Service functions to allow other WATERS (Watershed Assessment, Tracking & Environmental ResultS) services to process results asynchronously. At the center of the service is queue which receives and retains for a limited time the direct results of other WATERS services. Then using a simple identification code, the user may subsequently query the Results Queue Service to either determine if processing is complete or fetch completed results.

EPA Water Services - Spatial Assignment Service The WATERS Web and Database services provide open interfaces to complex analyses. These services make extensive use of the NHD and referenced program data in the RAD, and also integrate other WATERS program data. Designed as loosely coupled modular units, the services are developed in a common architecture. The Spatial Assignment Service is a support service allowing users to associate spatial information with reference layers stored in WATERS (Watershed Assessment, Tracking & Environmental ResultS). The intention of the service is not to report or analyze all interactions with the reference layer but rather to assign a single result. Provided parameters allow several means to resolve multiple matches including hinting via parameters, spatial analysis, distance analysis or simple arbitrary choice.
