It contains data on the location and consturction of Kansas wells drilled for water and water-related purposes. WIZARD consolidates information fomerly maintained by several local, state, and federal agencies. For wells that are part of the statewide or local water-level observation networks, WIZARD contains an historic record of water levels measured at various times during the year. Most of these data consist of annual measurements of depth-to-water taken in the winter, but some wells are measured on a quartley or monthly basis. Except for location information, data are not complete for all wells. WIZARD is owned and maintained by the Kansas Geological Survey (KGS) for use by the citizens and agencies of the State of Kansas. WIZARD resides physically at the KGS in Lawrence, Kansas as an ORACLE relational database consisting of 19 related tables.

No water quality data is provided in this database. A good portion of the archived WWC5 records are in the form of electronicly scanned images of the forms themselves. As such, the only standard database items entered into an Oracle RDBMS relate to the location information of the WWC5 wells, use of the well, when the well was completed, status of the wells, well depth, static water elevation, and the name of the drilling company servicing the site.

In 1836 the Maine Legislature authorized the first geological survey of the State, thus beginning a process of geological inquiry which continues today. A modern geological survey with full-time staff and an active field program evolved by the early 1940s to meet the resource demands of a growing population and the strategic mineral needs of a nation at war. Program emphasis through this early period was on economic resources including dimension stone, ore minerals, and clay. In the 1960s and 1970s a major exploration boom was fueled in part by the survey's detailed reports on ore deposits. While economic aspects remain a part of survey programs, the burgeoning population of southern and coastal Maine has required us to refocus our resources toward ground water and coastal marine issues. By using a modern geographic information system we are improving the analysis of map information and our ability to make high quality maps available to the public.

Data from these wells are used to assess ground water resources, determine long term trends, interpret impacts of pumping and climate, plan for water conservation, evaluate water conflicts, and otherwise manage the water resource. Soil and Water Conservation Districts under contract with DNR Waters measure the wells monthly and report the readings to DNR Waters. Readings are also obtained from volunteers at several locations.

A randomized grid design was established across the state, with a grid node spacing of 11 miles. A well from each principal aquifer that is used as a source of drinking water was selected within a nine-mile target area centered on each grid node.

Permits are issued to businesses, industries, local governments and individuals that take into account physical, chemical and biological standards for water quality. Figure 2 identifies programs that routinely collect information about groundwater water levels.

 Wisconsin Department of Natural Resources, Groundwater Retrieval Network (GRN)
This system reports data from the Department's Public Water Supply (public drinking water supply wells), Private Water Supply (private drinking water supply wells, non-point source priority watershed projects, and special groundwater studies), the Bureau of Waste's Groundwater and Environmental Monitoring System (GEMS) (landfill wells) and the Bureau of Watershed Management's System for Wastewater Applications and Monitoring Permits (SWAMP) (wastewater treatment facilities and land spreading sites). Data covers the period from the early 1970s to present for the Public Water Supply data; 1988 to present for the Private Water Supply data; from the mid 1970s to present for the GEMS database; and from the mid 1970s to present for the SWAMP system. The SWAMP data must undergo review from the facilities and only previously reviewed data is available. Not all programs which currently generate groundwater related data are linked into the GRN system. Data from the Bureau of Remediation and Redevelopment (LUST, spills, or remediation sites) is not currently retrievable through the GRN system.

Wyoming Water Development Commission, Wyoming State Water Plan, Statewide Water Resources Data System (WRDS)
The 1996 Legislature directed the Wyoming Water Development Commission (WWDC) and the State Engineer's Office (SEO) to prepare recommendations for updating the 1973 Wyoming Framework Water Plan. The two agencies submitted a joint recommendation to the Governor, the Select Water Committee, and the Water Development Commission on October 1, 1996.
