San Bernardino and Ontario have earned a dubious distinction as the dirtiest cities in California, according to a new report from Visual Capitalist. San Bernardino ranked as the dirtiest city in the entire United States, with Ontario not far behind in sixth place.
The rankings, which include cities from across the country, take into account factors like air quality, pollution, infrastructure, and living conditions. Other cities making the top 10 include Newark, New Jersey, Las Vegas, Nevada, and Phoenix, Arizona. The study highlights the serious health risks posed by poor air quality and waste management, with impacts on respiratory health and the spread of disease.
