The USGS Active Groundwater Level Network includes about 20,000 wells that have been measured by the USGS or USGS cooperators at least once within the past 13 months. The animation shows snapshots of water-level statistics in the network during December 2021.

This is a still image from the U.S. Groundwater Conditions animated data visualization, which depicts groundwater levels at 2,281 well sites across the U.S.

Graph of decadal change in Radium concentration compared to road salt application rate (Lindsay and others, 2021). Increases in concentrations of radium are correlated with road-salt application, and multiple lines of evidence support that the relation is causal.

Vehicles drive on interstate I-70 in Glenwood Canyon, Colorado. In the summer of 2021, travelers in Colorado's Glenwood Canyon were safely evacuated before massive debris flows buried highways and destroyed bridges, thanks to a debris flow warning system developed in part by the U.S. Geological Survey.

In this photo, USGS scientist Martha Nielsen conducts a slug test in a groundwater well completed in bedrock. During a slug test, a hydrologist causes the water level in a well to increase or decrease rapidly, while measuring the water-level response in the well over time.
