UST Site Closure Achieved Following Colloidal Carbon and Bioremediation Treatment

Case study highlights:

• Site cleanup objectives achieved, offsite drinking water protected
• The use of PetroFix enabled the site to earn a No Further Action Status
• PetroFix achieves over 97% Benzene reduction in weathered bedrock

A petroleum odor discovered in a residential production well led to the identification of an underground storage tank (UST) release at an upgradient active gas station. The contamination plume, containing high levels of total petroleum hydrocarbons (TPH), specifically benzene, threatened eight nearby residential drinking wells. Given the urgent need for remediation, PetroFix® was chosen over other methods, including ozone, due to its rapid and effective treatment capabilities. This first-ever PetroFix application in Alabama was highly successful, achieving the site cleanup objectives to demonstrate offsite drinking water protection and earning the site a No Further Action Status.
