USGS hydrologists deploy fiber-optic distributed temperature sensing equipment in Ashumet Pond, Mashpee, Massachusetts. Fiber-optic distributed temperature sensing is an emerging technology that has promise for characterizing estuary-aquifer interaction. The technology evaluation was conducted by the USGS Office of Groundwater Branch of Geophysics in 2007.

USGS hydrologists monitor data collection during a geophysical survey using the horizontal-to-vertical ambient-noise seismic method. This method can be used to estimate unconsolidated sediment thickness and map the bedrock surface as part of groundwater investigations.

Example of a pump and plumbing configuration used by public water systems. About 105 million peopleor more than one-third of the Nation's populationreceive their drinking water from one of the 140,000 public water systems across the United States that rely on groundwater pumped from public wells.
