San Bernardino tops list of California’s dirtiest cities, L.A. No. 2

A new study has put California in the spotlight — and not in a good way. Out of more than 300 major U.S. cities ranked from most to least dirty, four California cities landed in the top 10, including the No. 1 spot.

The ranking comes from LawnStarter , a national lawn care company, which analyzed data from 303 of the country’s largest cities. The study evaluated cleanliness using four key categories: pollution, living conditions, waste infrastructure, and how dissatisfied residents are with their environment.
