Interactive map of groundwater levels in Maryland

The Maryland Geological Survey, in cooperation with the U.S. Geological Survey, maintains a state-wide network of groundwater observation wells. The data from these wells is used to create an interactive map of groundwater levels in Maryland. The map provides both historical and recent groundwater reading levels across a range of aquifers in the state of Maryland.

Interactive map of water wells in Illinois

The Illinois State Geological Survey (ISGS) is the official repository for the records of existing wells that have been drilled in the state of Illinois. With records for over 700,000 wells, the interactive water wells map allows users to explore a range of information including the location, depth, and bedrock topography for all recorded wells in Illinois. Data for water and related wells exists for private water wells, engineering borings, and stratigraphic borings.

New data measure water losses across the Western U.S.

On December 16, NASA and U.S. Geological Survey (USGS) scientists released separate studies reporting significant declines in groundwater in the Western U.S.
