<br />Project Engineer, MAAP OU-4 Region I
<br />Groundwater Treatment System, USACE, Milan,
<br />TN. Provided engineering support on the design of the
<br />groundwater treatment plant with a design treatment
<br />capacity of 1,300 gpm. The treatment system consisted
<br />of eight groundwater extraction wells installed to
<br />maximum depth of 222 feet, chemical feed system for
<br />pH adjustment, influent tank, sand filtration, drying
<br />beds, granular activated carbon adsorbers and backwash
<br />system, and effluent re-aeration & discharge structure.
<br />Conducted field QA/QC and construction support.
<br />Prepared operations and maintenance (O&IvI) manual.
<br />
<br />Lead Engineer, 102nd Street Landfill Superfund
<br />Site, Oxychem and Olin Chemical corporations,
<br />Niagara Falls, NY. Responsible for the design of $16
<br />million aqueous phase licluid (.APL) and dense non
<br />aqueous phase liquid (DNAPL) recovery, loadout
<br />facility, slurry wall, and landfill cap. Design components
<br />included slurry wall, .APL recovery trench, NAPL
<br />recovery wells, embankment/bulkhead extending into
<br />Niagara River, clay and geosynthetic cap, and relocation
<br />of utilities and storm drainage. Surface runoff rates and
<br />infiltration through the landfill cap were estimated.
<br />Detailed engineering was performed to protect Niagara
<br />River and bedrock aquifer while minimizing treatment
<br />cos ts.

<br />Senior Hydrogeologist, Fernald Environmental
<br />Restoration Program, US Department of Energy
<br />(DOE), Fernald, OH. Developed scope of \vork,
<br />supervised subcontractor personnel, and modeled
<br />hydraulics and contaminant migration of radio nuclides at
<br />the Fernald site in support of the RI/FS and remedial
<br />design for the CERCLA/RCRA Unit 2 (CRU2). CRU2
<br />units comprise the Solid Waste Landfill, Lime Sludge
<br />Ponds, South Field, and Flyash Piles. Three dimensional
<br />point and block kriging, a geostatistical technique, was
<br />used to define source terms for a multi-layered, multi-
<br />component S\VIFf-based fate and transport model.
<br />Surface water, seeps, vadose zone, and groundwater
<br />models were linked together to provide inputs for risk
<br />assessment. Used inverse modeling technique to identify
<br />high permeability channels for on site disposal facility
<br />site selection. Also used fate and transport modeling to
<br />demonstrate protectiveness of disposal cell design and
<br />locate disposal cell over a sole source aquifer. HELP

<br />model was used to estimate infiltration and runoff rates
<br />from the landfill cap.
<br />
<br />Senior Hydrogeologist, Big D Campground, Olin
<br />Chemical, Kingsville, OH. Developed plans,
<br />managed investigation, and modeled hydraulics and
<br />contaminant migration at this Superfund site with
<br />complex boundary conditions. The IvlODFLOW based
<br />model was used to design groundwater extraction system
<br />that differed from the extraction trench system proposed
<br />in the ROD. The fInal groundwater remediation system
<br />consisted of eight wells and an artificial recharge trench.
<br />Revised design resulted in saving of more than $1
<br />million dollars. Supervised construction and assisted in
<br />the startup of the groundwater extraction system.
<br />LandfIll was excavated and contaminated soils and
<br />drums were incinerated using an on site incinerator.
<br />
<br />Senior Engineer and Hydrogeologist, RI/FS for Six
<br />Sites, Omaha ID/IQ, Ft. Lee, VAU. Responsible for
<br />hydrogeologic evaluations, fate and transport modeling,
<br />and feasibility study for the maintenance building,
<br />military in field training, reformatory landfill, former
<br />wastewater treatment site, and pesticide mixing sites.
<br />Contaminants of concern include volatiles, semi
<br />volatiles, pesticides, and metals.
<br />
<br />Hydrogeologist, Letterkenny Army Depot, US ACE,
<br />Chambersburg, PA. Evaluated multiple dye trace
<br />study data in a karst geology w,ith solutionally enlarged
<br />fractures, voids, sinkholes, springs, and caves. Assisted
<br />in hydrogeologic interpretations, fate and transport
<br />analysis, and develop remedial goals for Southeast .Area
<br />(OUS) RI/FS, Off-post Groundwater (OU6) RI/FS,
<br />and Truck Storage Area (OU7) RI/FS.
<br />
<br />Lead Hydrogeologist, ALCOA Point
<br />Comfort/Lavaca Bay Superfund Site, US EPA,
<br />Point Comfort, TX. Provided technical oversight for
<br />the RI/FS work at this site. Contaminants of concern
<br />included mercury, aluminum, and organic contaminants.
<br />Complex hydrogeology includes impacts of salt water
<br />intrusions, fresh water lakes, and man made dredge
<br />island.
