  2. Middle Rio Grande Basin Jemez Mts. Alluvial Fan Ancestral Rio Grande Sediments Santa Fe Gp., undivided Xsec from Connell, 2006

  3. Site Geology Alluvial Fan Interbedded Coarse and Finer Grained Sediments Anisotropy – Physical Properties Vary with Direction Ancestral Rio Grande Sediments Water Table Outcrop of sediment similar to what is at fuel spill site 3

  6. Conceptual Site Model • Define effect of water table fluctuations on locations and amounts of residual LNAPL • Identify natural degradation processes and potential opportunities for enhancement through engineered cleanup technologies Residual LNAPL Hydrocarbon oxidation in soil and groundwater Conceptual Site Model Before Interim Corrective Measures Reductive debromination of EDB comingled with EDB hydrolysis hydrocarbons 6

  10. EDB Plume Over Time • Diagram at top illustrates EDB plume thickness • Beginning to see evidence of plume collapse • Pumped approximately 500 million gallons as of October 2018 • Treated effluent is non-detect for all fuel constituents 10

  11. Response to Water Level Rise • 6 new monitoring well locations • First effort focused on new monitoring wells to fill data gaps that resulted from unexpected rapid rise in water table in first half of 2017 11

  12. Response to Water Table Rise • 8 soil cores to be drilled to determine extent of On-base Randolph Road remaining LNAPL in the source area • 1 background location • 3 optional locations that may be drilled pending results of other cores • 5 drilled boreholes will be completed as groundwater monitoring wells and 2 boreholes will be completed for soil vapor monitoring 12
