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. 

In this photo USGS hydrologist Allison Trcka collects a groundwater sample at the Idaho National Laboratory in November 2021. Since 1949, the USGS has partnered with the U.S.

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.
