2 Texas cities are among the 'dirtiest' in US: study

Two of the most populous cities in Texas have ranked high among the nation's filthiest in a recent study that highlights the ongoing challenges of urban cleanliness.

(NEXSTAR) -- Two of the most populous cities in Texas have ranked high among the nation's filthiest in a recent study that highlights the ongoing challenges of urban cleanliness.

LawnStarter, a lawn care provider, evaluated more than 150 of the largest cities in the U.S., focusing on pollution, living conditions, infrastructure, and resident satisfaction.

The study analyzed data from various federal agencies, including the Centers for Disease Control and Prevention, Census Bureau, Department of Energy, and Environmental Protection Agency.

Houston topped the list of so-called dirtiest cities due to high levels of pollution, a significant cockroach problem, and greenhouse gas emissions from large industrial plants.

Researchers also cited a 2022 report from the nonprofit media organization Grist, which found that some of Houston's "petrochemical facilities severely violated EPA safety guidelines."

Texas is the highest energy consumer in the nation across all sectors, KXAN previously reported. More than half of the state’s energy consumption comes from the industrial sector, including refineries and petrochemical plants.

Back in April, the EPA announced that chemical plants like those in Texas’ Gulf Coast must reduce toxic air pollution to help safeguard public health.

Despite these challenges, some Houstonians report higher satisfaction with their city’s cleanliness compared to residents in 33 other large cities.

The cities that rounded out the top five include Newark, New Jersey; San Bernardino, California; Detroit, Michigan; and Jersey City, New Jersey. Meanwhile, another city in the Lone Star State, San Antonio, came in at No. 7. Here's the full top 20:

1. Houston, Texas
2. Newark, New Jersey
3. San Bernardino, California
4. Detroit, Michigan
5. Jersey City, New Jersey
6. Bakersfield, California
7. San Antonio, Texas
8. Fresno, California
9. Oklahoma City, Oklahoma
10. Yonkers, New York
11. Shreveport, Louisiana
12. New York, New York
13. Birmingham, Alabama
14. Ontario, California
15. Los Angeles, California
16. Modesto, California
17. Palmdale, California
18. Hollywood, Florida
19. Las Vegas, Nevada
20. Fort Lauderdale, Florida

Several California cities -- such as Bakersfield, Fresno, Los Angeles, and San Bernardino -- also ranked among the dirtiest. San Bernardino had the most dissatisfied residents regarding cleanliness for the second year in a row.

Additionally, the study highlighted the Southwest's water issues, worsened by drought and climate change. Las Vegas was named the dirtiest in the region, ranking at No. 19, while Chandler, Arizona, is the cleanest at No. 71.

In Ohio, cigarette litter is a common problem across the state, according to the study. Cleveland had the highest percentage of smokers (29.1%), leading to litter problems despite strict laws. Columbus, however, had the lowest (22.1%) and is one of the cleaner cities overall at No. 137.

On the flip side, Virginia Beach, Virginia, stood out as the cleanest city for the second year in a row, showcasing low pollution levels and high consumer satisfaction. Other top performers included Fremont, California; Winston-Salem, North Carolina; and Des Moines, Iowa.
