A persistent sewer odor hanging over an East Mesa neighborhood has left residents frustrated, worried, and, in some cases, feeling ill. Neighbors living near the Mesa–Apache Junction border say the smell has lingered for weeks and intensified recently, with some reporting headaches, nausea, and being unable to enjoy time outdoors.

What Residents Are Reporting

Several neighbors describe the odor as overwhelming, comparing it to the smell of something dead. One resident told reporters the stench has become so strong it’s affecting his ability to work and spend time outside. Many say their calls to the emergency number posted at the nearby sewer lift station went unanswered or received only vague assurances that the issue would be checked.

Where Officials Say the Problem Originates

Residents believe the odor is coming from a sewer lift station operated by the Apache Junction Sewer District. District staff allowed reporters inside the facility, explaining that while hydrogen sulfide monitors show zero parts per million—indicating the air is technically safe—the smell is real and likely tied to recent system changes. With more than 1,500 homes now connected, new pumps were activated, and officials suspect that shift may be contributing to the odor.

Steps Being Taken

To better understand the problem, the district has installed odor sensors throughout the neighborhood to monitor air quality around the clock. Officials also acknowledged delays in responding to complaints and said they are considering new ways for residents to report odor issues more effectively. Results from the new sensors are expected within two weeks.

County and State Involvement

Maricopa County has asked the Arizona Department of Environmental Quality to investigate the situation and determine whether further action is needed. Until answers come, residents say they’re staying indoors and hoping for relief.
