has been and continues to be an important source for credible groundwater data. Regional investigations may involve either the collection of new data and/or the compilation of existing data from state geological surveys, city and county agencies, regional authorities, well drillers, and previous USGS studies.

Elementary school students studying the hydrologic cycle may make best use of regional or national hydrologic data in an aggregate form as charts, graphs, and tables. A researcher or consultant investigating hazardous chemical migration at a particular location might require primary chemical and hydrologic data with a full array of metadata (e.g., sampling protocol, analytical method, drilling method)

To facilitate data flow between regional and local studies, data should include explicit information on measurement scale. Data from individual observation wells should contain a pointer to available local, aquiferwide, and regional data, including groundwater usage information, hydraulic characteristics, aquifer characteristics, and geologic information.

The national maps shown on the main screen in these databases are cTickable down to the state or county level, where there is a listing of stream gauges linked directly to downIoadable data, metadata, and graphs. These databases are a resource to the nation and represent the type of data presentation we would like to see for groundwater data and other USGS WRD data.

Other informative sites include the lower TIlinois basin NAWQA site (http://wwwil.usgs.gov/proj/lirb/~. Unlike the surface water sites discussed previously, most maps presently are not georeferenced and are therefore not clickable.

is capable of displaying points such as wells, lines such as streams, and polygons such as outlines of regional groundwater project domains or welThead protection areas, (4) has a thematic structure that would allow related groundwater information to be found and accessed easily, (5)

In order to facilitate timely information delivery and communication between scientists, most ongoing regional and national investigations with a length of two years or more should establish a project web page that includes a description of the project, identification of project investigators and cooperators, project location, anticipated final and interim products, and data availability. Such web sites should also include, where appropriate, online project reports and links to georeferenced project databases.

The USGS enjoys a reputation for providing value-neutral free or low-cost primary and interpretive data for public use on natural resources issues. It is essential that this reputation be protected and that the USGS continue to be a reliable and unbiased source of data and information.
