Emergency Response: Identifying and Mitigating Petroleum Vapor Intrusion at an Active Gasoline Station

The Solution

Over the following months, ARM worked closely with the client and MDE to implement remedial measures to prevent continued vapor intrusion.

To evaluate subsurface conditions, ARM developed an investigation plan, which included:

• Installation and sampling of indoor and outdoor vapor monitoring points and sampling of indoor air.
• Installation and sampling of nine monitoring wells to assess soil and groundwater conditions.
• Use of sonic drilling technology to minimize surface disruption while improving sampling efficiency.
• Real-time data analysis to guide remediation strategies.
• Regulatory coordination with MDE to ensure compliance and site safety.

The subsurface investigation was implemented in March 2025. 

The Outcome

The remediation efforts allowed the gasoline station to resume operations within a timely manner with MDE approval. Following data analysis, ARM will develop a long-term monitoring and corrective action plan based on investigation findings, ensuring continued compliance and environmental safety.
