Facility Explorer Help


Welcome to the Facility Explorer—a data warehouse of the Iowa Department of Natural Resources (DNR)—that brings together core environmental information in one place for easy access by DNR staff and the public. 


Use it to explore environmental information collected by Iowa DNR to answer questions such as:


Some of these questions can be answered now; others will be answered as it nears completion.  Facility Explorer is a constantly growing system.  Check out the Current Status and Future Plans.

Layer Explanations

Find out details about a layer by clicking on  to the right of each layer. This will take you to the metadata described in Iowa DNR’s GIS library.


Iowa Layers

Many additional layers are available as shown in the example at right.






Air Emissions

This report provides a map of facilities with air quality permits, known as Title V, in a given radius, and a table of details about air emissions from those sites.  It is useful when gathering information for an air quality construction permit for Prevention of Significant Deterioration (PSD).

NOTE:  If you want a quick list of only the facilities (not their emission points), do the same Radius Search, but under View Results, select As a List. 


Leaking UST

This report provides a map of Leaking Underground Storage Tank sites in a given radius, and a table of details about those sites.  It is useful for identifying petroleum-contaminated areas to be avoided when proposing to construct new wells.


Well Search

This report provides a map of known wells in a given radius, and a table of details about those wells.  It is useful for identifying wells near Leaking UST sites or for finding nearby wells when applying for a Water Use permit.  The All Wells layer can only be viewed if you are logged in and have been granted user rights.  To request permission to view wells, please go to https://programs.iowadnr.gov/wellsearch/pages/wslogon.aspx.

Report An Error

If you see data on Facility Explorer for a site that you believe is incorrect, you have the ability to report an error.  Some examples may include: the facility name is wrong, the owner is incorrect, the site’s location is not correct.  When you report an error, you should also if possible identify the correct information.  Errors that are reported will be routed to contacts in the appropriate program area for further review and correction if needed.   The contact person will respond to you within seven days to let you know about the outcome of their review.  It is therefore very important that you provide your contact information, as well as detailed identification for the site.


To report an error, click the “Report Error” link at the top of the Map or Site Detail page.  You then will complete the form that appears with as much detail as possible.





Your first and last name and email are required.  If you can identify the DNR program that the site is associated with in the DNR Program dropdown menu, please select it.   Also, if you know the programID (usually a permit, registration, or facility identifier), please enter that.  If you do enter a programID, a selection from the DNR Program drop down will also need to be made.  The State Facility ID is a nine digit identifier that appears in the top section of the Site Detail page of Facility Explorer.  The Federal Facility ID is a twelve digit number that also appears in the top section of the Site Detail page. In the Error Description input box, enter a detailed explanation of the incorrect data, as well as what you believe the correct data to be.  Finally, click the Submit button to complete the submission of the report.
