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

EDB Plume Over Time
- Diagram at top
illustrates EDB plume thickness
- Beginning to see
evidence of plume collapse
- Pumped
approximately 500 million gallons as
- f October 2018
- Treated effluent is

Response to Water Level Rise

- 6 new
monitoring well locations
- First effort focused
- n new monitoring
wells to fill data gaps that resulted from unexpected rapid rise in water table in first half of 2017
SLIDE 12
Response to Water Table Rise
On-base Randolph Road
- 8 soil cores to be drilled to
determine extent of 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
