Data Access Tools

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.

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.

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, 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.

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 following link:

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.
