These California cities ranked among the dirtiest in the US

The appeal of city living has its benefits, but these locales typically have dense populations and an accumulation of pollution and trash.

Some cities in America are affected by this problem more than others, and a new survey takes a closer look at it. 

House Fresh, an indoor air quality company, assembled a report ranking the dirtiest cities in the U.S.

To determine which city is the dirtiest, the team examined 12.3 million sanitation-related 311 complaints placed over the past year based on the number of reports made with populations of 100,000.

The team also assessed dirty cities by zip codes, and the 21213 zip code in Baltimore was number one with 89,391 sanitation-related complaints.
