Philadelphia is often referred to as the “City of Love” due to its rich history and culture, but many area residents are less enamored with the city's notoriously dirty streets. The city's streets can accumulate litter from vehicles, people and wind-blown debris. Narrow street widths and the lack of a standardized sidewalk sweeping program also contribute to Philly’s dirtiness. Poor maintenance of sewer systems and drainage infrastructure can also lead to frequent flooding, further aggravating the problem. 
In recent years, Philly has taken steps to address its filth issue by increasing enforcement of littering laws, utilizing public workers and contracting teams to sweep sidewalks and install green stormwater infrastructure in some neighborhoods; however more work is needed in order for the cityscape to improve drastically.

Philadelphia has a long history of industrial pollution, dating back to the early 1800s, when the city was a major hub of manufacturing. Additionally, due to its location on the Delaware River, Philadelphia was a gateway for polluted runoff from nearby states. This combination of factors has contributed to high levels of air and water pollution in the region, giving Philadelphia its nickname: "The Dirtiest City in America."
