Well Inventory Search Help

General tips for entering search criteria:

• Some criteria fields allow more than one value to be selected from a list. In these fields, the list appears with a scrollbar allowing you to scroll through all of the items in the list. To select more than one item in the list, hold the CTRL key down while clicking on your selections.
• Use the "Submit" button to perform your query. The criteria you have entered will be used to select the results of the query, which will then be displayed on a new page after the query has completed.
• Use the "Reset" button to clear any criteria you have entered.

The following criteria are available for searching the well inventory:

1. WI Unique Well #: Between zero and five WI Unique Well Numbers may be entered to restrict the wells retrieved. Each valid well number uniquely identifies a single well.
2. County: Zero or more counties may be selected to restrict the wells selected to particular counties in Wisconsin.
3. Survey Township, Survey Range, Survey Range Direction, Survey Section: You may specify Public Land Survey System location information to zero in on the location of the wells. Multiple selections of townships, ranges, or sections can be made. However, it is recommended that multiple selection only be done at the finest level of detail being specified, otherwise the query will not really make sense. So, if township, range, and section are all being specified in your criteria, multiple selection should only be done at the section level.
4. Well Address: You may specify all or part of a well's street address. The query will look for any Well Address containing the text you type. The matching is not case-sensitive. For instance, entering "main" will match a well with a street address of "103 S. MAIN ST".
5. FID: If you know the facility identifier of a well, it may be entered as criteria.
6. Well Use: Zero or more types of well use may be specified as criteria. Follow these links to get the definitions of the various types of well use that exist: Municipal Community, OTM Community, Non-transient Non-community, Transient Non-community, Private Potable, Non-potable Private, Monitoring Well, Piezometer, Unspecified Non-community, Groundwater Extraction Well.
7. Well Status: The current status of a well may be specified as criteria. You may often want to query on Active wells, for instance.
