Residents living near the City of Amarillo landfill received reassuring news this week after state environmental officials reported no air quality concerns stemming from the massive wildfire that originated at the facility earlier this month.
According to information released by Amarillo Mayor Cole Stanley on May 28, the Texas Commission on Environmental Quality (TCEQ) conducted air monitoring around the landfill and surrounding neighborhoods following the fire and found no harmful compounds in the air.
The testing was performed in response to ongoing concerns from residents who questioned whether smoke and burning waste materials at the landfill could have created hazardous air conditions. The mayor requested the follow-up investigation to ensure those concerns were addressed and to provide the public with verified information from state regulators.
TCEQ personnel conducted monitoring Tuesday afternoon around the perimeter of the landfill and in nearby residential areas affected by the fire. State investigators reported that oxygen levels remained within normal ranges throughout the monitoring period. The agency also found no detectable levels of sulfur dioxide, hydrogen sulfide, volatile organic compounds, or gamma radiation during the testing process.
The findings offer a measure of relief to residents who watched the fire spread rapidly from the landfill into neighboring communities. The blaze, which became widely known as the “Stinky Fire” because it originated at the city landfill, burned approximately 2,335 acres and prompted significant emergency response efforts.
The fire was first reported on May 17 at the landfill located northwest of Amarillo near Bezner Road. Fueled by dry conditions and strong winds, the fire quickly expanded beyond the landfill boundaries, threatening hundreds of homes in nearby neighborhoods.
City officials reported that more than 300 homes were at risk during the incident. The fire ultimately destroyed dozens of residences and damaged many others. Various reports indicate that 77 homes were either destroyed, damaged, or otherwise impacted by the disaster, including 52 homes that were completely lost and 25 that sustained damage.
As firefighting operations continued, TCEQ investigators conducted an on-site inspection on May 19. During that visit, portions of the landfill's working face were still smoldering while crews worked to suppress remaining hot spots. Fire suppression efforts included the use of water trucks, heavy equipment, and specialized firefighting chemicals designed for landfill fires.
The city also contracted HazMat Special Services to assist in identifying underground hot spots hidden beneath the landfill surface. Using radar technology and specialized equipment, crews worked to locate and extinguish burning waste materials that could reignite if left untreated.
According to the state investigation, city landfill personnel followed established standard operating procedures for managing landfill fires during the emergency response. TCEQ's final assessment concluded that no harmful compounds were detected in neighboring areas during air quality monitoring efforts.
The landfill itself operates under a Type 1 municipal solid waste permit and plays a significant role in the region's waste management system. State records indicate the facility accepted more than 284,000 tons of waste during fiscal year 2025.
While the air quality findings help answer one of the most pressing questions raised after the fire, city officials continue to assess the full scope of damage caused by the disaster. Final estimates regarding financial losses, infrastructure impacts, and recovery costs are still being compiled.
The investigation into the fire and its aftermath remains a topic of interest throughout the Amarillo area, particularly for residents who experienced property losses or evacuation orders. For now, state environmental regulators say their testing found no evidence that the landfill fire created harmful air contamination in surrounding neighborhoods, providing important reassurance as the community continues its recovery efforts.
