Toxic Legacy: The Environmental Impact of the Cochise St. David Waste Incinerator
The Cochise St. David Waste Incinerator, located in southeastern Arizona, has been a source of controversy and concern for local residents and environmental groups for decades. The incinerator, which was operated from 1984 to 1998, burned hazardous waste, including toxic chemicals and heavy metals, posing significant risks to the environment and public health. Despite being shut down over 20 years ago, the legacy of toxic pollution left behind by the incinerator continues to affect the community and ecosystem, highlighting the importance of responsible waste management and environmental stewardship.
History of the Incinerator
The Cochise St. David Waste Incinerator was built in 1984 by the Arizona-based company, Cochise Environmental Inc. The facility was designed to burn hazardous waste, including chemicals, pesticides, and heavy metals, from various industries, including manufacturing, mining, and agriculture. The incinerator was touted as a state-of-the-art facility, with claims that it would provide a safe and efficient way to dispose of hazardous waste. However, from the outset, the facility was plagued by problems, including equipment malfunctions, leaks, and emissions of toxic pollutants.
Environmental Impact
The incinerator’s operations had a devastating impact on the environment. The facility released a cocktail of toxic pollutants, including dioxins, furans, and heavy metals, into the air, water, and soil. These pollutants can cause a range of health problems, including cancer, neurological damage, and reproductive issues. The incinerator’s emissions also contaminated the surrounding soil and groundwater, posing a long-term threat to the ecosystem and public health.
Studies conducted by the U.S. Environmental Protection Agency (EPA) and other agencies have documented the extent of the environmental damage caused by the incinerator. For example, a 1995 EPA study found that the facility’s emissions had contaminated the soil and groundwater with high levels of dioxins, furans, and heavy metals, including arsenic, lead, and mercury. The study also found that the incinerator’s operations had released large quantities of particulate matter, nitrogen oxides, and sulfur dioxide into the air, contributing to poor air quality in the region.
Health Impacts
The health impacts of the incinerator’s operations have been significant. Local residents have reported a range of health problems, including respiratory issues, cancer, and neurological damage. A 2001 study published in the Journal of Exposure Science and Environmental Epidemiology found that residents living near the incinerator had higher levels of dioxins and furans in their blood and urine than the general population. The study also found that exposure to these pollutants was associated with increased risks of cancer, reproductive problems, and neurological damage.
Cleanup Efforts
In 1998, the incinerator was shut down by the Arizona Department of Environmental Quality (ADEQ) due to repeated violations of environmental regulations. Since then, the site has undergone several cleanup efforts, including the removal of contaminated soil and groundwater. However, the cleanup process has been slow and incomplete, with many areas of the site remaining contaminated.
In 2019, the EPA announced a plan to conduct a comprehensive cleanup of the site, including the removal of contaminated soil and groundwater. The agency estimated that the cleanup would take several years to complete and would cost tens of millions of dollars. While the cleanup efforts are a step in the right direction, many local residents and environmental groups remain concerned about the long-term health and environmental impacts of the incinerator’s operations.
Lessons Learned
The Toxic Legacy of the Cochise St. David Waste Incinerator serves as a stark reminder of the importance of responsible waste management and environmental stewardship. The incinerator’s operations demonstrate the risks associated with burning hazardous waste, including the release of toxic pollutants into the environment and the long-term health impacts on local communities.
The incident also highlights the need for stronger regulations and enforcement to prevent similar environmental disasters in the future. In the aftermath of the incinerator’s shutdown, Arizona strengthened its environmental regulations, including requirements for more stringent emissions controls and increased transparency and public participation in the permitting process.

The Cochise St. David Waste Incinerator’s toxic legacy serves as a cautionary tale about the importance of responsible waste management and environmental stewardship. The incinerator’s operations had a devastating impact on the environment and public health, and the cleanup efforts have been slow and incomplete. As we move forward, it is essential that we prioritize environmental protection and public health, and work towards a future where hazardous waste is managed in a safe and responsible manner. The Toxic Legacy of the Cochise St. David Waste Incinerator must serve as a reminder of the importance of protecting our environment and the health of our communities.
