from clinker material and sulfur filter cake. During the first project, source material containing lead, arsenic, and sulfur f1lter cake was removed, treated on-site, and disposed off at a Subtitle D Landfill. The source material was very acidic (PH less than 1.5) and classified as hazardous waste material. The source material was stabilized on-site with Enviroblend (a triple superphosphate) and neutralized with Portland cement and/ or limestone screening. The second project was to develop EE/CA Work Plan, FSP, QAPP, and HASP and implement them. Project approach used streamlined human health and ecological risk assessments to idcntify and remediate soil, sediments, and groundwater. Groundwater pH was as low as 0.6. Field X-Ray Fluoresccnce (XRF) analysis was used to delineate areas requiring removal actions and select soil/sediment samples for confirmatory analysis by an off-site laboratory. Lead a project team of five contractors. Project was completed under an Administrative Order on Consent bet\veen EP 1\ Region IV and Respondents. Project Engineer, Enhanced In-situ Bioremediation, Storage Technology Corporation, Palm Bay, FL. Developed \vork plan to conduct pilot tests to evaluate feasibility of using lactic acid or soybean oil to in-situ degrade 1,1,I-trichloroethane and 1,1- dichloroethene. Lactic acid was injected in an area and site was monitored to define full-scale design parameters. The purpose of the bioremediation system was to close the site under the Florida Brownfield Program. A full-scale bioremediation system is currently being designed. Project Engineer, Haines Street Overpass, Florida DOT, Jacksonville, FL. Evaluated impacts of construction dewatering on an off-site chlorinated hydrocarbon plume. A counter pumping system using dewatering points was designed and implemented so that the plume's size is not increased and the main part of the plume did not migrate. Counter pumping dewatering point locations were adjusted over 5-month construction period. Options were evaluated for discharge of extracted and treated water to a surface water body using an NPDES permit, POT\V, and artificial recharge for this time critical project. Extracted water was treated on-site and discharged to a surface water body under a NPDES permit. Senior Hydrogeologist, Fleet and Industrial Supply Center (FISC) Yorktown, LANTDIV, DESC, Department of Navy, Yorktown, VA. Developed a site conceptual model based on boring log, site historical information, and aquifer tests. Conceptual model included previously unidentified t\vo clay layers that were critical in defining the distribution of Navy special fuel oil (NSFO) in the aquifer. Developed a 3-dimensional model to simulate a coupled fluid and heat transport model based on the PORFLO\'(! software. Model included effects of temperature on viscosity of NSFO that ranged from over 500 centis tokes to 70 centistokes. \'Vater level changes over a short distance range up to 30 feet. Model \vas calibrated to pre-remediation average water levels and temperature distribution resulting from heating with Phase 1 steam lines. Developed capture zones and effect of steam lines and hot water injection in support of the Phase 2 system design. System was designed so that NSFO will not be drawn under a clay layer and get trapped during seasonal water fluctuations and cone of depression caused by recovery trenches. Project Engineer, Chloride Plume at Site 30-3 , Triple S Corporation (Kerr McGee), Felda, FL. Conducted slug tests. Used Time Domain Electromagnetic (fDEI\.I) soundings to determine horizontal and vertical chloride distribution. One hundred seventy-six (176) TDEM soundings were used to survey over 225 acres of citrus groves. Thin-bed analysis was used to define chloride distribution in 5 to 12 feet thick laycrs to a depth of 214 feet. Information was used to develop a MODFLOW based fate and transport model and determine recovery well locations to control chloride plume and remediate the site. Designed a remedial system and prepared a Remedial Action Plan (RAP) that used a deep injection well to discharge extracted saline water. Senior Hydrogeologist, Former Metro North Property (Mott Haven), New York City School Construction Authority, Bronx, NY, 11/2005- 02/2006. Provided design support for a grout wall that severed a dual purpose in that it was to provide additional structural support for school building and to provide a hydraulic barrier to off-site, up gradient SHAW ENVIRONMENTAL, INC. 2 06C 122006T AMAR CHAND SUMS, PHD., P.E.
