Lake Pepin Emergency Spill Response

Lake Pepin Emergency Spill Response

Fuel and oil spills present immediate dangers and can leave lasting impacts on the environment. These incidents must be acted upon by professionals who provide a fast response and are knowledgeable in emergency ecological assessments.

Pinnacle Engineering responds to incidents 24/7, guiding through site analysis, investigation, and clean-up efforts while providing regulatory representation. Our assessments and testing encompass a wide variety of factors to analyze the extent of environmental contamination.

Environmental Challenge

A client contacted Pinnacle Engineering after 1,500 gallons of diesel fuel were released within 70 feet of Lake Pepin and the Mississippi River. As a result of the spill, fuel infiltrated the ground and impacted the shallow water table. The location of the spill was in a rail track bed, which further complicated remediation.

Emergency Response & Remediation Solutions

Emergency spill response is time-sensitive due to the speed at which contaminants can penetrate the soil and pollute groundwater and nearby natural resources. Pinnacle Engineering’s team arrived on site with a vac truck within two hours of the release. We immediately started soil vapor removal to extract the pooled fuel and prevent further penetration into the soil. The vac truck allowed us to address the spill without having to pull up portions of the rail track.

Removing pooled fuel was the first and most urgent step in remediation efforts. The second phase of cleanup involved removing contaminated soil located above the water table to prevent pollution.

Analysis & Results

As a result of our team’s quick response, we were successful in recovering all of the pooled fuel from the spill site. Within 50 days of the initial spill response and containment phase, a preliminary investigation was completed and an interim corrective action, consisting of an air sparge/soil vapor extraction (AS/SVE) system was initiated. The system operated for nine months, reducing the impacts to the soil by approximately 90%, removing LNAPL, and reducing impacts to groundwater in the source well to nearly undetectable levels within two years.

Our goal is to continue to build upon our reputation of delivering high-quality services, maintaining open and responsive communications, and providing cost-effective solutions that consistently meet our clients’ needs.
