Landfill Sighting vs. Native American Reservations and National Parks in Arizona

This map shows the location of landfills in relation to both Native American Reservations data from the United States Department of Agriculture National Agriculture Statistics Service and National Park data from Google Maps. There is one Native American owned and operated landfill located within the reservation, but other than that, there are no landfills within reservations, meaning that Native Americans outsource their waste for the most part. There are three landfills in the Tonto National Forest, two within the Grand Canyon National Park, and one in the Gila National Forest; National Parks are apparently acceptable locations for landfills in Arizona.

Landfill Sighting vs. Housing Values in Arizona

This map shows landfill locations mapped against housing value estimate data from the US Census Bureau. Landfills seem to be condensed around the areas of highest housing values, especially around Phoenix and Tuscon. They are spread evenly across areas of low housing values. Additionally, landfills are located near the borders of the state, and proximal to major roads.

Landfill Sighting vs Fault Lines in Arizona

This map shows Landfills mapped against the fault lines in Arizona. The fault line data are from the Arizona Geological Survey, and they were put up October of 2010. While the two main criteria for the sighting of landfills are proximity to fault lines and flood plains, there are still several landfills located reasonable close to fault lines. The major trend, however, is to keep landfills away from areas of high fault line concentrations, such as the northwest and central portions of the state.

Landfill Sighting vs Population in Arizona

This map shows the location of landfills relative to population data from the 2003 US Census. In areas of low populations landfills are spread over a large area, and are evenly distributed. Highly populated areas, however, have high concentrations of landfills; more people produce more trash, so it is logical to have more landfills close to the source of the garbage. Within these divisions, landfills are located near major roads to minimize the distance of transportation.

Landfill Sighting vs. Per Capita Income in Arizona

This map shows landfill sighting mapped against per capita income data from the 2003 US Census. Overall, landfills are distributed fairly evenly through different income levels throughout the state. However, there is a major concentration of landfills in the highest income bracket, around Phoenix AZ, but this is probably attributed more to the concentration of population around a major city than the actual income levels. Within the income level divisions, landfills seem to be sighted based on proximity to major roads.


California



Map #1: “Landfills and Per Capita Personal Income in California”
This map shows the locations of California’s landfills mapped against per capita personal income by county. The 2003 per capita personal income attribute presented in this map is from the National Atlas of the United States and is available at http://nationalatlas.gov/. All of the landfill locations in the state that are shown on the map are provided by the US Environmental Protection Agency. Landfills in the northern part of the state are evenly distributed among counties that represent lower levels of per capita personal income in California. While landfills in the southwestern part of the state are considerably greater in number, they are also among some of the counties with the highest level of per capita personal income in California and are not distributed evenly among counties.
---------------------------------------


Map #2: “Landfills and Average Wage Per Job in California”
This map shows the locations of California’s landfills mapped against average wage per job by county in 2003. This data is from the National Atlas of the United States and is available at http://nationalatlas.gov/. All of the landfills in the state that are shown on the map are provided by the US Environmental Protection Agency. On this map the distribution of landfills are greater in the western and southern part of the state and are located in some counties that are categorized as the highest level of wage per job in California. Landfills in the western part of the state are evenly distributed among counties with a lower average wage per job.
--------------------------------------



Map #3: "Landfills and Population Density by County in California"
This map shows the estimated resident population for California counties in 2003 mapped against the locations of California’s landfills. Population of each county in California is from the National Atlas of the United States and is available at http://nationalatlas.gov/. All of the landfills in the state that are shown on the map are provided by the US Environmental Protection Agency. The locations of landfills in the southern part of California are unevenly distributed among counties that have the most population density. While landfills in the northern part of the state are evenly distributed among counties with lower population density, there is a far greater concentration of landfills in the southern part of the state.
-------------------------------------




Map #4: “Landfills and African American Population by County in California”
This map shows the locations of California’s landfills mapped against the African American population by county. The demographic attribute of race presented on this map is from the 2008 U.S. Census Bureau and is available at http://www.census.gov. All of the landfills in the state that are shown on the map are provided by the US Environmental Protection Agency. Landfills in California are unevenly distributed among counties with higher populations of African Americans. The counties with the highest population of African Americans can be found in the southern and western parts of the state. While landfills are evenly distributed among counties in the northern part of the state, they are also classified with fewer populations of African American and fewer landfills in California.
--------------------------------------




Map #5: "Landfills and Hispanic Population by County in California"
This map shows the locations of California’s landfills mapped against the Hispanic population by county. The demographic data on this map is from the 2008 U.S. Census Bureau and is available at http://www.census.gov. All of the landfills in the state that are shown on the map are provided by the US Environmental Protection Agency. This map indicates that the locations of California’s landfills are unevenly distributed on counties with higher populations of Hispanic people. The Hispanic population is primarily located in the southern part of the state. The majority of counties in the northern part of the state has much less Hispanic population and also has exceedingly fewer landfills than the southern part of California.
