What's Happening?
Burns & McDonnell's Environmental Services team has successfully employed 3D subsurface modeling to accelerate and enhance the remediation of a former Manufactured Gas Plant (MGP) site in Illinois. These sites, prevalent across the U.S. from the 1800s
to mid-1900s, often leave behind extensive coal tar contamination in soil and groundwater. The project involved a property owner needing remediation before repurposing the land. Geologist Ben Lockwood noted the challenge of determining the extent of contamination at MGP sites, which can vary significantly. The team faced an abundance of data from over 360 investigation locations, making traditional 2D modeling methods slow and inefficient. By adopting advanced 3D modeling software like Leapfrog and OpenGround, Burns & McDonnell was able to process vast datasets, iterate models rapidly, and gain a clearer understanding of contaminant migration pathways, significantly improving the site characterization and remediation planning process.
Why It's Important?
The successful application of 3D modeling by Burns & McDonnell in Illinois highlights a significant advancement in environmental remediation practices across the United States. The efficiency gained through this technology, particularly in managing complex MGP sites, translates directly into substantial cost savings for property owners and potentially for taxpayers, as many of these legacy sites require extensive cleanup. The ability to iterate models in minutes rather than hours or overnight drastically reduces project timelines, allowing contaminated land to be repurposed more quickly. This approach also provides environmental consultants with a higher degree of confidence in their remediation strategies, ensuring more effective cleanup and reducing long-term environmental risks. This method could become a standard for addressing the thousands of MGP sites nationwide, mitigating the environmental and health impacts of historical industrial pollution.
What's Next?
The success of 3D modeling in this Illinois MGP remediation project suggests a potential shift in how environmental consulting firms approach complex contamination sites. Other firms and regulatory bodies may increasingly adopt or recommend similar advanced modeling techniques to improve efficiency and accuracy in remediation efforts. This could lead to broader implementation of 3D subsurface modeling across the U.S. for various environmental challenges, not just MGP sites. Furthermore, the demonstrated cost and time savings could incentivize property developers and industrial landowners to proactively address legacy contamination, knowing that more efficient tools are available. The continued development and integration of such technologies will likely shape future environmental policy and best practices for site assessment and cleanup.
Beyond the Headlines
The 'mothball legacy' of Manufactured Gas Plants represents a widespread and often overlooked environmental challenge across the U.S., with thousands of sites posing risks to soil, groundwater, and potentially human health. The adoption of 3D modeling goes beyond mere technical efficiency; it signifies a more sophisticated and proactive approach to environmental stewardship. By providing unparalleled insight into subsurface contamination, this technology allows for more precise and targeted remediation, minimizing disruption and maximizing the effectiveness of cleanup efforts. This shift towards data-driven, technologically advanced solutions underscores a broader trend in environmental science, where innovation is crucial for addressing the complex and persistent issues left by industrial history. It also raises ethical considerations regarding the responsibility of current generations to address the environmental burdens inherited from past industrial practices.
