Groundwater Data for the Nation
The USGS has successfully restored all of the operational gages that stopped transmitting due to an issue with the satellite telemetry system that records and transmits data.
The focus of this study is on analysis of existing hydrologic, chemical, and microbiological data; collection of surface-water and shallow ground-water hydrologic, chemical, and microbiological data; and characterization of dissolved organic carbon composition.

Groundwater and Streamflow Information Program
Groundwater in basin-fill aquifers of the Southwest often increases in dissolved-solids content as it travels along its flow path as a result of geochemical interactions with the aquifer matrix and through evaporative processes. At the end of its flowpath, groundwater may be brackish or saline and discharges to the surface through springs such...

The Upper Floridan aquifer is close to land surface and in some areas is in direct contact with streams in the lower ACF Basin. Groundwater pumping in this area can result in lower streamflow that adversely affects aquatic biota in streams and rivers.
This map shows estimated concentrations of atrazine in shallow groundwater beneath agricultural land. Atrazine use is one of the most important factors used to predict atrazine and deethylatrazine concentrations in groundwater (right). Within areas of high atrazine use, groundwater residence time, soil permeability, and other factors explain some...
