Concentrations of strontium in samples of groundwater from drinking-water wells and shallow monitoring wells. Concentrations in drinking-water wells that exceeded the health-based screening level of 4,000 micrograms per liter largely occurred in carbonate-rock aquifers, particularly in southern Florida and central Texas, and in areas where upwelling brines mix with potable

What do USGS Hydrologic Technicians do on the job? This video features five different Hydrologic Technicians from Washington Water Science Center and Nevada Water Science Center sharing some of their work. This video was sponsored by the USGS Hydrologic Data Advisory Committee.

This is an animation showing the changing conditions of USGS streamgages from July 1, 2020 to September 30, 2020. The conditions shown range from the driest condition seen at a gage (red open circles) to the wettest (blue closed circles). There is also a purple ring added to indicate gages that are flooding. At the beginning of July, the Southwest US experienced severe
