<br />contaminants flowing onto thc property via
<br />ground\vater. A sheet-pile wall perpcndicular to the
<br />grout wall was also part of the dcsign. r,[ODFLO\,(!
<br />based groundwater model was developed to e,'aluate
<br />potential groundwater mounding created by the
<br />proposed grout wall and sheet-pile wall and to determine
<br />thc likelihood of contaminated groundwater flowing
<br />O\'er the top the proposed grout wall. r,[odel simulated
<br />the hydraulics of the aquifer for an area of approximately
<br />2,200 feet x 3,400 feet is size with 10 vertical layers.
<br />Significant topographic relief occurred \vith the modeled
<br />area that resulted in complex lithologic sequence.
<br />Hydraulic conducti,'ities of the grout wall and sheet-pile
<br />wall and the relati,'e depth of the hydraulic barrier with
<br />respect to the top of competent rock \vere varied to
<br />determine the sensiti,'ity of the predicted groundwater
<br />mound and determine the likelihood of contaminated
<br />groundwater flowing over the grout wall. Using the
<br />results of the ground\vater model, a recommendation
<br />was made for design of the grout wall and sheet-pile
<br />wall.

<br />Project Engineer, MAG-1 Area Remediation, Ft.
<br />Dix, NJ, 3/2006-Present. De,.eloped fate and
<br />transport model using ~[ODFLO\\' and RT3D in
<br />support of designing an in-situ enhanced bioremediation
<br />of chlorinated sokent plume. A 3-D regional model
<br />cm'ering approximately 8,300 feet x (i,200 feet area was
<br />de,'eloped to capture complex hydrogeology of the site
<br />that includcd se"eral streams, \vetlands, and a regional
<br />aCluifer that was influenccd by groundwater supply wells.
<br />.-\ local was model was then de,'eloped for contaminant
<br />transport \vithin the plume area. De,'eloped pilot test
<br />work plan. Currently, awaiting appro,'al of the pilot test
<br />\vork plan to implement it in the field.

<br />Project Hydrogeologist, Building 505 (SWMU
<br />79/80), Former Myrtle Beach Air Force Base,
<br />Myrtle Beach, SC, OS/2005-02/2006. De,'eloped a
<br />groundwater model to simulate remediation of
<br />trichloroethene and daughter product plume. The
<br />shallow and deep groundwater aCluifer were impacted.
<br />The shallow groundwatcr is influcnced by drainage
<br />ditches. This resulted in groundwater flow occurring in
<br />opposite directions in the shallow and deep zones that
<br />are separated by a silty clay layer. A regional flow model
<br />covering approximately 3 mile x 3 mile area was

<br />developed to capture complex hydrogeology and pro,'ide
<br />boundary conditions for a local model for 500 feet x 500
<br />feet plume. r,[odel was uscd to predict under what
<br />conditions acti,'e remediation system can bc shut down
<br />and let natural attenuation take m'er.

<br />Lead Engineer, Defense Fuel Supply Point, Defense
<br />Energy Supply Center, Charleston, SC. Responsible
<br />for the investigation and design of soil npor recovery
<br />and groundwater trcatment system to remove JPA
<br />contamination. Treatment system consisted of oil-water
<br />separation, air stripping, carbon adsorption, and
<br />reinjection. Therc are at least four scparate plumes
<br />impacting residential and industrial properties.
<br />Dc,.eloped corrective action plans (Cl\PS), site-specific
<br />target le,'els (SSTLs), obtained pcrmits, and prm'ided
<br />regulatory interface. Enluated existing system,
<br />conducted fate and transport modeling, and optimized
<br />grounchvater remediation system.

<br />Project Engineer, 1-10/1-95 Interchange, Florida
<br />DOT, Jacksonville, FL. Dcsigned dewatcring systcm
<br />and temporary water treatment plant to rcmO\'c organic
<br />contaminants. Treatment s)'stems included filtering, air
<br />stripping, and carbon adsorption.
<br />
<br />Hydrogeo[ogist, Sarasota Maintenance Yard,
<br />Florida DOT, Sarasota, FL. Used RT3D to determine
<br />sources of chlorinated sokents. r,[odel rcsults indicated
<br />that off-site sources were responsiblc for contaminants
<br />scen at the site. This work lead the FD EP to pursue
<br />responsible party for off-sitc contamination. l\lso
<br />directed field ilwestigations.

<br />Abandoned Landfill, Abandoned Landfill,
<br />Confidential, Upstate, Sc. Pro,'ided expert testimony
<br />on site h)'drogeology, conceptual model, and
<br />contaminant migration from an abandoned landfill in a
<br />fractured aCluifer. The court ga"e a judgment in favor of
<br />the client.

<br />Senior Hydrologist, Coleman-Evans Superfund Site,
<br />USACE, Whitehouse, FL. Reviewed work plans and
<br />design documents and participated in coordination
<br />mcctings for groundwater operable unit and additional
<br />soil sampling along General Avenue and water treatment
<br />facility.
