Environmental investigation, LUST remediation, and vapor intrusion risk mitigation services for a commercial/residential site in Michigan.
A leak from an underground storage tank (UST) at the H & P Gas site (also known as Pic-N-Pac) was discovered on October 21, 2020, in a primarily commercial/residential area. The release of unleaded gasoline impacted soil and groundwater both on-site and on adjacent off-site properties. Redevelopment and construction activities in the surrounding area required delineation of contamination, risk assessment, and long-term monitoring to ensure public and environmental safety.
The site presented complex challenges due to the mixture of commercial and residential land uses, requiring coordination with property owners, regulatory agencies, and ongoing management of residual contamination while allowing for safe use and redevelopment of affected properties.
AKT Peerless conducted a comprehensive remedial investigation and ongoing environmental oversight, including delineating the horizontal and vertical extent of unleaded gasoline in soil and groundwater through soil borings and permanent monitoring wells, assessing soil gas contamination on off-site properties, and evaluating residual LNAPL presence. The team obtained Site-Specific Target Levels (SSTLs) from EGLE, prepared and submitted the Initial Assessment Report (IAR) and Final Assessment Report (FAR), and implemented quarterly groundwater and soil gas monitoring. AKT Peerless reported monitoring results to EGLE and property owners, confirmed plume delineation, and coordinated the closure of the release using institutional controls, including a Deed Restriction Covenant (DRC) and Property Health Impact Controls (PHIC), ensuring regulatory compliance and safe ongoing property use.
AKT Peerless successfully characterized the extent of the unleaded gasoline release and implemented monitoring and mitigation strategies to protect public health and the environment. Continuous groundwater and soil gas monitoring confirmed delineation of the plume and effectiveness of risk mitigation measures.
Through coordination with EGLE, off-site property owners, and institutional controls, the release was closed in compliance with regulatory requirements, enabling safe ongoing use and potential redevelopment of affected properties.
