RCRA Facility Investigation (RFI) Approach

 

The primary objectives for the proposed RFI activities are to utilize an iterative framework to collect the necessary, relevant, and targeted data to:

​​

• Delineate impacts of areas to be investigated

​

• Evaluate potential groundwater migration pathways

​

• Evaluate impact, if any, to the shallowest potable aquifer – Sunburst Formation

​

• Investigate refinery on-site sewer system

​

• Delineate impact from legacy refinery operations

​

• Evaluate utility preferential pathways (i.e. West Rail AOC-39 to the Missouri River)

​

• Characterize natural source zone depletion
