TOXMAP and Native American Populations

Although TOXMAP is not specifically designed for any one particular group, the TRI and Superfund Programs can be of interest to specific populations such as Native Americans by helping to find sources of chemical releases and contamination in locations of interest to them.


The Toxics Release Inventory (TRI) Program provides information on the industrial release and handling of certain chemicals that may pose a threat to human health and the environment. Certain US facilities specified by law must report to the US Environmental Protection Agency (EPA) how much of each chemical is released, recycled, or managed. This information is collected annually in the TRI.


The EPA Superfund program is part of a federal government effort to clean up land in the United States that has been contaminated by hazardous waste and that has been identified by the EPA as a candidate for cleanup because it poses a risk to human health and/or to the environment.


To locate Indian reservations or rancherias in TOXMAP classic, click on "Zoom to a Place", enter "reservation" or "rancheria" into the "other place name" search box, then click "Submit".


In the newer, Adobe Flash-based TOXMAP, click on the "Zoom to Location" icon, enter "reservation" or "rancheria" into the "Address or Place" search box, then click "Zoom to":

You can also save the location for later use by clicking the "Bookmarks" icon (picture of a book icon). You can then use the "bookmark" to zoom to that location for quick reference later in your session or at a later date.


Also in the Adobe Flash-based TOXMAP, click the "Native Lands (AI / AN / NH)" layer to show the locations of American Indian Reservations and Off-Reservation Trust Lands, Alaska Native Village Statistical Areas, and Hawaiian Home Lands, as defined by the US Census. This layer can be toggled on and off via the Map Contents side panel:

In both versions, you can also overlay US Census data by race: "American Indian and Alaskan Native" (1990 and 2000) or "American Indian" (2010):
