Air quality, waste management, and pollution control aren’t just environmental concerns—they’re also a big part of a city’s livability. LawnStarter’s 2025 “Dirtiest Cities in America” ranking looked at 20 factors across 303 major U.S. cities, from industrial emissions and roadway pollution to the share of residents unhappy with their environment. The results show a mix of repeat offenders and surprising newcomers.

For the second year in a row, San Bernardino, California, ranks as the dirtiest city in the countrySeventy-five percent of residents report dissatisfaction with local pollution. It’s also one of 10 California cities tied for worst median air quality. Adding to the challenge, San Bernardino County has over 850 warehouses of 100,000 square feet or larger, which may contribute to higher nitrogen dioxide levels.

Los Angeles comes in at No. 2,ranking high for near-roadway pollution—nearly 40 percent of residents live near heavily trafficked roads—and overcrowded homes. In third place is Detroit, Michigan, where high smoking rates and public dissatisfaction drive its poor score. Reading, Pennsylvania comes in fourth, with greenhouse gas emissions and a top-ranked toxic release score pushing it up the list. Ontario, California, rounds out the top five, despite making strides in sustainable development and clean energy initiatives. Read on for the top 25 and their scores.

Your comment may not be far off. Kek.

11 of the 12 California cities on the "dirtiest cities in the country" list are in SoCal. One, Stockton is in the Central Valley. No city in Northern California are listed.

Granted, there are more people and overwhelmed local services not designed for the endless overload on every sector from courthouses to schools to traffic (as opposed to planned growth), and related homelessness and crime, directly connected to the encouraged-by-traitors invasion from the south and elsewhere (x 20+ years, the Trump years excepted).
