RR Sites Map

RR Sites Map, now available for the desktop and mobile devices, is the DNR's web-based mapping system that provides information about contaminated properties and other activities related to the investigation and cleanup of contaminated soil or groundwater in Wisconsin. RR Sites Map is part of DNR's Wisconsin Remediation and Redevelopment Database (WRRD), an inter-linked system tracking information on different contaminated land activities.


About RR Sites Map

This online mapping application allows users to view different layers of contamination data using a desktop, tablet or smart phone.

RR Sites Map includes (but is not limited to) the following environmental data:

  • completed and ongoing investigations and cleanups of contaminated soil and/or groundwater;
  • public registry of sites with residual soil or groundwater contamination, or where continuing obligations have been put in place;
  • cleanup of sites under the federal Superfund (CERCLA) statute;
  • liability exemptions and clarifications at contaminated properties (i.e., brownfields); and
  • DNR funding assistance.

The status of cleanup actions for sites in RR Sites Map is tracked via the Bureau for Remediation and Redevelopment Tracking System (BRRTS). The RR Sites Map data is linked to the BRRTS database through BRRTS on the Web (BOTW).

Note: Links to PDF documents (including the GIS Registry Packet) are only on BOTW. To get to the PDF from RR Sites Map click on the site using the "Identify" button, then click on "View Activity Details on BOTW" in the results panel.

Map layers

Map layers

Below are the definitions of the layer themes in RR Sites Map. More detailed definitions of each of the layers are available from the application by clicking on the "Layer Information" button/tool.

1. Contaminated and cleaned up sites

Includes sites where cleanup of environmental contamination is ongoing or completed. A "site" is a contamination incident, not a property. A site may be smaller than a property or may include more than one property.

2. GIS Registry

Includes sites where one or more of the following continuing obligations were included in a closure letter (closed sites), a remedial action approval letter (open sites) or in a liability clarification letter for a Local Governmental Unit (LGU exempt status).

  • Residual soil and/or groundwater contamination was above environmental standards at the completion of the cleanup and must be managed according to applicable environmental laws and rules.
  • Continued monitoring was approved or required.
  • A monitoring well needs to be properly abandoned, if/when located in the future.
  • Land use is limited to industrial, due to application of industrial soil standards for closure.
  • Maintenance of a barrier (e.g., soil cover, engineered cover, pavement or other barrier) is required at the site.
  • A structural impediment (e.g., a building and/or cement slab) is present at the site. which prevented a complete investigation and cleanup. Further action is required in the future if/when the structural impediment is removed.
  • Use of a vapor mitigation system is required.
  • Notification of the Department is required before the use of the property is changed from commercial or industrial to a residential type use; and additional action may be needed.
  • Additional actions may be necessary if a building is constructed, modified or if use of a building or the property changes.
  • A site specific condition is present.
  • A local government unit is required to take an action to maintain a liability exemption (s. 292.24, Wis. Stats).
  • Additional actions may be necessary if a building is constructed, modified or if use of the property changes.

3. Liability limitations and clarifications

Includes sites where DNR has:

  • written a general liability clarification letter to answer environmental liability questions;
  • approved a permanent liability exemption based on a thorough investigation and cleanup of a property through the Voluntary Party Liability Exemption (VPLE) process; or
  • worked with EPA to place a site on the Superfund National Priorities List (NPL).

4. DNR financial actions

Includes sites where DNR has:

  • provided financial assistance via grants, loans or other reimbursements; or
  • hired an environmental consultant because no responsible party is available.

Does not include sites cleaned up using Petroleum Environmental Cleanup Fund Awards (PECFA).

User tips

There are a suite of tools available on RR Sites Map depending on whether you are using a desktop or mobile device. The desktop application has the most comprehensive tool set. When using a mobile device you will find there tool set simplified to accommodate mobile devices.

User tips

  • To view the map layers click on the "Show Layers" button
  • There a few different ways to find a site:
    • Use the "Find Site" button on the "Navigate" tab to search by BRRTS Number, Activity Name or Facility ID
    • If you know the location use the zoom in/out tools or on a mobile device touch the screen and spread fingers apart or pinch them together
    • Use the Address Search Tool - click on "Search for Address" in the "Navigation" tab and fill in the fields on the left (include street type (e.g. Ave, Rd, St etc)). Note the address search only finds an address not the actual property
  • Find information about a site:
    • Select the " Identify" button in the "Navigate" or "Map and Data Tasks" tab, and then click or drag your mouse or finger (mobile devices) over a symbol on the map. You will find a link to more database information in the results pane.
  • After clicking on a site from the GIS Registry layer theme, learn about the site-specific requirements for managing residual contamination by selecting the "View Activity Details on BOTW" link in the results pane. There are several contacts available that can assist with viewing a complete state file.

Further user tips are available by clicking on the "Information" tab on RR Sites Map.

Note: The user tips are specific to the desktop. Location of tools may vary or may not be available on mobile devices.



For complete information about all contamination incidents known to DNR, please use BRRTS on the Web, which provides a summary of actions at every site where a hazardous substance discharge has been reported to DNR. BRRTS on the Web is also accessible by a link from locations in RR Sites Map (See "Navigating Quick Tips" above under "Resources").

RR Sites map does not include:

  1. hazardous substance "spills" (i.e., locations where a cleanup confirmed by laboratory analysis is generally completed within 60 to 90 days);
  2. some recent sites that have not yet been mapped;
  3. some sites with soil contamination above chapter NR 720 residual contaminant levels for cleanups approved prior to August 1, 2002 in the GIS Registry layer theme (in progress);
  4. locations where a discharge or potential discharge has been reported to DNR and DNR has determined that no investigation is required; and
  5. sites never reported to DNR.
