Emerging PetroFix Application Approach: Underground Storage Tank (UST) Basin Flood
PetroFix® can be flooded into active tank basins to help address dissolved contamination that may be resident from prior releases and that may be difficult to reach with normal injection approaches. PetroFix also can be pre-applied to gravels and basin or utility cavities during installation of fuel infrastructure following a previous leak and remediation project, or during scheduled replacement of pipelines and underground storage tanks. This pre-application prevents contamination of clean backfill and reduces the risk and spread of future pollution events. Preventative treatment costs will be low and provide savings by avoiding/reducing the scale of any remedial works needed. PetroFix is a liquid form of activated carbon and so can provide unequalled coverage and coating of bedding materials. It spreads easily, is non-toxic and safe to handle and apply.
Case Study: PetroFix Applied To Active UST Basin, Quickly Meeting Cleanup Goals
This case study reviews an active gasoline station in Colorado where stained soils were discovered during the replacement of the underground storage tank (UST) spill buckets. After considering multiple options, CGRS, a leading environmental consulting firm, developed and implemented an innovative, low-risk, and highly cost-effective treatment program utilizing PetroFix to address the groundwater contamination in situ.
Emerging PetroFix Application Approach: Emergency In-Situ Spill Response
While hydrocarbon spill response methods reduce the immediate impact of a spill, residual risks remain because remaining hydrocarbons can form groundwater plumes that may threaten downgradient receptors or cross property boundaries. Eventual remediation of these residual risks can be costly because the time between emergency response and formal remedial assessment takes time while contaminants continue to migrate. Unfortunately, movement of residual contamination over boundaries can result in extra complexity and cost. PetroFix Remediation Fluid can be used in combination with other spill response methods such as excavation as a downgradient properly line barriers preventing plume encroachment (as shown in the figure above) or a trench or excavation surface coatings that reduce the vertical migration and formation of dissolved contamination in situ after a spill. A case study highlighting the latter scenario is linked below.
