Technical Resources

Ground-Water -- The Office of Ground Water pages are designed to provide useful information about ground-water resources of the Nation and ground-water activities of the USGS.

Surface-Water -- The Office of Surface Water provides leadership in development and application of new techniques and tools for the collection, analysis and interpretation of surface-water and sediment data.

Water-Quality -- The Office of Water Quality provides leadership and coordination in the development of programs to address issues concerning the quality of the Nation's surface-water and ground-water resources, and provides support in the application of techniques for the collection, analysis, and interpretation of water-quality data.

Software -- For water resources applications made available to be used in the public interest and for the advancement of science. An archive of programs and documentation on geochemical, ground-water, surface-water, water-quality, and general topics. Includes such favorites as MODFLOW.

Research -- The National Research Program conducts basic and problem oriented hydrologic research in support of the mission of the USGS. The program is designed to encourage pursuit of a diverse agenda of research topics aimed at providing new knowledge and insights into varied and complex hydrologic processes that are not well understood.

GIS -- Water Resources Node of the National Spatial Data Infrastructure (NSDI).

Projects -- find about the various resource assessment and research activities of the Water Resources Division.

Hydrologic Instrumentation Facility -- supports USGS hydrologic data-collection activities through the identification of needs, development of technical specifications, design or development of specialized interfaces, contracts and procurements, testing and evaluation, specialized field applications, repair and calibration, quality control and assurance, and storage and distribution of hydrologic instrumentation.

Branch of Quality Systems -- Part of the Office of Water Quality this program manages and operates water-quality quality-assurance projects for the USGS and provides training and coordination on developing quality-assurance programs for the USGS.

National Water Quality Laboratory -- Fulfills analytical requirements of the USGS by analyzing environmental samples for inorganic, organic, and radiochemical constituents.

Chlorofluorocarbon Laboratory -- The Reston Chlorofluorocarbon Laboratory provides analytical services for determination of the chlorofluorocarbons (CFCs) CFC-11, CFC-12, and CFC-113, sulfur hexafluoride (SF6), and other gases in air and water samples in support of USGS hydrologic studies to trace the flow of young water (0- to 50-year time scale) and to determine the time elapsed since recharge (ground-water age).
