9 Arizona Cities Among The 'Dirtiest Cities' In America

Do you live in one of the dirtiest cities in the U.S.?

Big cities and metropolitan areas aren't the only spots affected by factors like air quality or pollution. Even smaller towns are impacted by environmental factors, overconsumption and human interference that add up to a destination in need of "sustainable investments" to help improve quality of life.

LawnStarter compared more than 300 cities across the country to determine which are the "dirtiest cities" in America, analyzing the locales based on categories like pollution, inadequate living conditions and waste infrastructure as well as resident dissatisfaction. Nine cities in Arizona made the list, including one that ranks in the Top 10:

• No. 7: Phoenix
• No. 18: Mesa
• No. 27: Tempe
• No. 36: Peoria
• No. 38: Scottsdale
• No. 52: Tucson
• No. 61: Flagstaff
• No. 66: Chandler
• No. 117: Yuma

These are the 10 dirtiest cities in America, according to the report:

1. San Bernardino, California
2. Los Angeles, California
3. Detroit, Michigan
4. Reading, Pennsylvania
5. Ontario, California
6. Newark, New Jersey
7. Phoenix, Arizona
8. Jersey City, New Jersey
9. Las Vegas, Nevada

Here's how LawnStarter determined its rankings of the dirtiest cities in the U.S.:

"For each of the 500 biggest U.S. cities, we then gathered data on each factor from the sources listed [on the site]. We eliminated 197 cities lacking sufficient data in a single category, resulting in a final sample size of 303 cities. Finally, we calculated scores (out of 100 points) for each city to determine its rank in each factor, each category, and overall. A city's Overall Score is the average of its scores across all factors and categories."
