National Environmental Methods Index (NEMI)
NEMI is a searchable database of environmental methods, protocols, statistical and analytical methods, and procedures that allows scientists and managers to find and compare methods for all stages of the monitoring process.
Estimated Annual Agricultural Pesticide Use
View the geographic distribution of Estimated Annual Agricultural Pesticide Use in the conterminous United States. A graph accompanies each map, which shows annual national use by major crop for the mapped pesticide for each year during the period.
Water-Quality Changes in the Nation's Streams and Rivers
This mapper provides results from the largest-ever assessment of water quality changes in the Nation's streams and rivers. More than 185 million water-quality records from over 600 Federal, State, Tribal, and local organizations were screened as part of this assessment.
Groundwater Quality: Decadal Change
Almost one-half of the U.S. population rely on groundwater for their water supply, and demand for groundwater for public supply, irrigation, and agriculture continues to increase. This mapper shows how concentrations of pesticides, nutrients, metals, and organic contaminants in groundwater are changing during decadal periods across the Nation.
GeoLog Locator
The USGS GeoLog Locator is a web-based tool that allows allows users to access more than 7,000 digital borehole geophysical logs and related data files at over 1,700 locations.
Geo Data Portal
The Geo Data Portal (GDP) provides access to numerous datasets, including gridded data for climate and land use. Datasets can be subsetted or summarized before download using several algorithms, and these algorithms can also be applied to other datasets hosted elsewhere.
Hurricane Irma's Water Footprint
Hurricane Irma, the most intense hurricane observed in the Atlantic in the last decade, approached the west coast of Florida on September 10th, 2017. This Hurricane Irma Water Footprint data visualization animates the hurricane's path, cumulative precipitation, and its impact on river gage height.
Water-use data available from USGS
The U.S. Geological Survey compiles water-use estimates every five years for each State, the District of Columbia, Puerto Rico, and the U.S. Virgin Islands. Archived datasets underlying the published "Estimated Use of Water in the United States" reports are available from the above link. County data incorporating any revisions can be found on NWISWeb.
Groundwater Levels at Selected Observation Wells in the South Coast of Puerto Rico
Depth-to-water is measured periodically to evaluate hydrologic conditions at important aquifers throughout Puerto Rico. The water-level measurements from observation wells can be computed to understand the hydrologic stresses acting on aquifers and how these stresses affect groundwater conditions.
GOM - Dashboard
Both the GOM Dashboard and the Sea-level Tool feature interactive maps for viewing either water data and associated weather data or the potential for flooding. Both maps are specific to regions along the Gulf of Mexico.
BEST Large Rivers Monitoring Network (LRMN)
The Biomonitoring of Environmental Status and Trends (BEST) Program's Large River Monitoring Network (LRMN) has examined fish health in multiple river basins by using a suite of organismal and suborganismal endpoints, which monitor and assess the effects of environmental contaminants in fish.
Yucaipa Valley Hydrologic Monitoring
This site provides hydrologic data collected or compiled by the USGS in the Yucaipa area; some additional data may be available from the USGS database National Water Information System (NWIS).
