City living comes with more entertainment, more job opportunities, but also more pollution, trash, and pests. A list has been compiled, taking into account air pollution, water quality, waste management, and resident dissatisfaction levels. America’s Dirtiest Cities aren’t necessarily full of litterbugs — cities like San Bernardino, California takes #1 on the list… and our own Detroit Rock City is #2. All cities that made the list primarily deal with polluted air, high levels of greenhouse gas emissions, and records of drinking water violations.
