Residents across the Roanoke Valley are reporting a strong, foul, sewage-like or chemical odor, with potential links to illegal dumping in the Blue Hills area and a reported gas leak investigation on Williamson Road NW. Additionally, poor air quality with high particulate matter (PM2.5) is present, contributing to hazy conditions.

Suspected Source 1 (Illegal Dumping): Residents near Orange Avenue have reported ongoing, illegal construction debris dumping, which can create strong, unpleasant odors.

Suspected Source 2 (Gas Leak Investigation): Roanoke Fire and Rescue have been investigating a potential gas leak on Williamson Road NW as of Feb 25, 2026.

Widespread Odor: Reports of the smell extend across Roanoke and Vinton, with some describing a “sewer-like” or “chemical” odor.

Air Quality: The air quality in the region is currently considered “poor” for sensitive groups, which may exacerbate environmental smells
