It may not be the ranking San Antonio city leaders wanted before thousands of tourists pour in for Fiesta, but according to a new report from air quality company HouseFresh, Alamo City is the No. 7 dirtiest city in the United States.

To size up American cities, HouseFresh analyzed 12.3 million sanitation-related 311 complaints made over the past 365 days. The firm zeroed in on a few categories like garbage, waste, and recycling, then weighted the rankings based on the number of grievances per 100,000 people.

San Antonio had 8,929 complaints per 100,000 people, putting it in line with Kansas City, Missouri (8,874) and Buffalo, New York (8,509). When the company did a deeper dive into specific ZIP codes, it pinpointed a few problem areas. 78202, which includes East Side neighborhoods like Dignowity Hill and Jefferson Heights, had the most per-capita complaints. The cleanest ZIP code, 78260, is outside the loop.

Although HouseFresh explained its methodology, it did not exactly specify what constituted a “complaint.” City representatives from Sacramento, California took issue with the findings, saying that it encourages residents to call 311 for any customer service request. Reporting a cracked bin lid or a late pickup could have been calculated into the overall figures without contributing to an overall sanitation problem.

In contrast to San Antonio and No. 10-ranked Dallas, Austin gleamed on the list. The Capital City came in at No. 20 with a mere 2,245 complaints per 100,000 residents. Sprawling Houston had a good showing, too. At No. 14 with 6,275 gripes, Space City also boasts proximity to the cleanest ZIP code in the U.S. — 77546 in nearby Friendswood.

Elsewhere in the nation, Baltimore, Maryland was zinged as the filthiest U.S. city, with a whopping 47,295 complaints. Milwaukee, Wisconsin was the spiffiest metro with a shockingly low 309 complaints per 100,000 people.
