The Kennewick Contamination Crisis: An Overview
The city of Kennewick, nestled in the southeastern corner of Washington state, faces a significant environmental challenge. Hazardous chemicals have been detected in the groundwater beyond the boundaries of the defunct Pasco Sanitary Landfill, signaling that recent extraction efforts have fallen short of completely eliminating the contamination. This situation has prompted the Washington State Department of Ecology to launch an investigation into potential vapor intrusion risks and develop strategies to immobilize the groundwater contamination.
The Pasco Sanitary Landfill: A Brief History
- Operational period: 1958 to 1993
- Location: Kahlotus Road and U.S. Highway 12, just outside Pasco city limits
- Designation: U.S. EPA Superfund site
- Size: Approximately 200 acres
- Surroundings: Agricultural land and commercial enterprises
Despite its proximity to farmlands, it’s crucial to note that the landfill is not within a designated drinking water area. Over the years, responsible parties have invested more than $75 million in cleanup efforts across various zones of the landfill, demonstrating a commitment to environmental remediation.
Recent Cleanup Efforts and Challenges
In June 2022, the Department of Ecology celebrated a significant milestone in their cleanup efforts. The final section of the landfill, known as Zone A, was excavated. This area contained a staggering 35,000 drums filled with hazardous industrial waste, including solvents and paints. The cleanup operation was particularly critical due to past incidents of underground fires, which raised concerns about potential smoldering pockets remaining in the landfill.
The scale of this operation was immense:
- 23,500 tons of waste removed (equivalent to 1,900 school buses)
- Soil in Zone A underwent thermal treatment to eliminate contaminants
- Approximately 9,100 pounds of harmful chemicals were successfully destroyed
Despite these efforts, the battle against contamination is far from over. Some contaminants persisted after the thermal treatment, including volatile organic compounds such as benzene and tetrachloroethene. These chemicals pose serious health risks, including potential carcinogenic effects and organ damage.
Ongoing Monitoring and Future Plans
The Department of Ecology is now engaged in further sampling to determine the extent of the new contamination spread. They are closely monitoring groundwater levels, especially given that past issues of groundwater contamination had been previously addressed. In the coming months, the department plans to:
- Inject chemicals into the groundwater to bind contaminants
- Curb contaminant movement beyond the landfill’s boundaries
- Address the groundwater plume outside the landfill in phases
- Install additional groundwater wells if necessary for thorough monitoring
At Farmonaut, we understand the importance of continuous monitoring in agriculture. While our focus is on crop health and soil moisture through satellite imagery, the principles of vigilant observation apply equally to environmental protection. Our API and developer documentation showcase how technology can be leveraged for comprehensive monitoring solutions.
The Vapor Intrusion Concern
A pressing concern that has emerged is the potential for vapors from the contaminants to migrate upwards and infiltrate nearby buildings. This risk is particularly acute for industrial warehouses located southwest of the landfill. The Department of Ecology is taking this threat seriously and has outlined the following steps:
- Assess soil gas concentrations
- If concentrations reach concerning levels, evaluate indoor air quality
- Implement remedial actions if required
This proactive approach to vapor intrusion highlights the complex nature of environmental contamination and the need for comprehensive monitoring systems.
Responsible Parties and Collaborative Efforts
The cleanup responsibility lies with a group of approximately 30 companies and organizations, collectively known as the Industrial Waste Area Group III. This group includes major corporations such as Boeing and DuPont, as well as government entities like the U.S. Air Force. Their collective commitment to resolving the ongoing contamination issues and safeguarding public health in the area is crucial for the success of this environmental remediation project.
