Eight Mile is an unincorporated community in Mobile County, Alabama, United States. The community is named for its distance from the city of Mobile. Part of it was annexed in the mid-20th century by the city of Prichard, Alabama.
Eight Mile is located west of Mobile Bay and just north of the Gulf of Mexico. The elevation is 33 feet (10 m).
The mostly African-American enclave had a median income in 2014 of $35,000. This is more than $8,000 lower than the state median.
In 2008 lightning struck a mercaptan storage tank at a Mobile Gas Service Corp. underground natural gas pipeline at the Whistler Junction gas transfer facility within the Eight Mile community. An estimated 500 US gallons (1,900 l; 420 imp gal) of Mercaptan, the chemical odorant added to natural gas to help detect leaks, spilled into the soil and groundwater for six months, according to Alabama state environmental officials. It has migrated to ponds and surfaced, polluting the community's air.
Beginning in 2011, residents in Eight Mile began complaining of an overwhelming mercaptan odor and associated health problems. They have concerns about the damage to their health from the chemical, and to property values from its persistent rotten egg smell.
