Get RSEI

RSEI is screening-level modeling software that you can download for free and run on your computer. RSEI analyzes risk factors including the amount of chemical released, the fate and transport of the chemical, the route and extent of human exposure to the chemical, and the toxicity of the chemical to produce a risk-related numerical score which you can use to compare to other model results.

This page describes how to get the RSEI model; what is new in the latest version, and tips for dealing with known problems RSEI users have encountered.

How to Get the RSEI Model

The RSEI Version 2.3.2 (using 1996-2011 TRI reporting data) Installation Package includes the setup executable. You may separately download the supporting information, including the Methodology, User's Manual, Toxicity Spreadsheet, and Technical Appendices. Users should also review the appropriate uses of RSEI (which can also be found here). You can download the Installation Package using the link below.

System Requirements: 2 gigabytes of free hard disk space, and at least 512 megabytes of RAM. Users must also have Internet Explorer Version 3.0 or later installed on their computer to use the RSEI Help feature. Administration rights are required for correct installation.

Download the Installation Package

Note to Users of Previous RSEI Versions:

Before installing the new version of RSEI, you should completely remove earlier versions of RSEI. This involves three steps:

  1. Remove RSEI using the Add/Remove Programs function in the Control Panel
  2. Locate the C:\Program Files\RSEI folder
    1. Copy any .qry files as well as other non-RSEI files that you would like to save out of this folder or the C:\Program Files\RSEI\user subfolder;
    2. Delete the entire C:\Program Files\RSEI folder.
  3. Delete the RSEI entries in the BDE Administrator
    1. Open BDE Administrator from the Control Panel
    2. Delete the entries for “Data”, “User”, and “Work”
    3. Delete entries (if there are any) that begin with EIM (e.g. “EIMDATA”).

With installation of RSEI Version 2.3.2, there is no longer a user directory at C:\Program Files\RSEI\user. Instead, RSEI stores your tables and queries in a folder called ‘RSEI Results’ which is installed under your Windows ‘Users’ directory, for instance, at C:\Users\Public\Documents\RSEI Results. Windows configurations may vary, so if you cannot find the folder there, a hard drive search for ‘RSEI Results’ will identify the location.

Census Files

The RSEI model uses decennial U.S. Census data to for 1990, 2000, and 2010 to create annual estimates of detailed population data, including age-sex information, for each grid cell for each year. These data, although used in creating RSEI scores, are not required when running the RSEI model and are not included in the RSEI Installation Package. However, they are available for download below. More information on how the Census files are created is contained in the User's Manual (PDF) (172 pp, 1.8 MB, About PDF)

What is New in Version 2.3.2

Each new version of RSEI incorporates the latest TRI data, as well as changes to the input data and the methodology used to process the data and present the results. The following changes were made in Version 2.3.2:

User Tips to Deal with Potential Problems

RSEI cannot find a data table
Users sometimes report errors that result from RSEI not being able to locate the appropriate data tables.  This error often arises from RSEI being installed while the user is logged into a local area network (LAN).  We recommend that you uninstall RSEI, log off of your LAN or disconnect network drives, then reinstall RSEI. If you have an earlier version of RSEI, we recommend you update to the current version.

Selections that produce zero facilities 
It is not unusual for users to report that a selection statement return no facilities or releases even though they know there are reports.  The most common reason for this error is a mismatch in the text.  For example, if you use lower case for state abbreviations (e.g. tx instead of TX), RSEI will return zero matches.  If you are unsure of what value you should put in a selection statement, use the “Help” feature or User's Manual (PDF) (172 pp, 1.8 MB, About PDF) to identify the appropriate data type (number, text, True/False) and format for that variable.

Users also sometimes use the incorrect any/all/none operator in a bracket statement.  For bracketed statements where the variable is the same, but the value changes (e.g. facility location.state is equal to TX; facility location.state is equal to LA), the appropriate operator is “any”.
