KEY PROJECT EXPERIENCE:

• Sixteen years of experience in the environmental industry specific to remedial investigations, feasibility studies, hydrogeologic assessments, construction management, and in-situ soil and groundwater remediation and water supply.

• Since 1987, has served as a vice president of the engineering and consulting division of INTEX. Responsibilities include management and supervision of Project Managers, Engineers, Geologists, and other environmental professionals and technicians; review and approval of deliverables; and tracking and justification of budgets. Responsible for projects located predominantly in New York, New Jersey, and Pennsylvania.

• Henderson Road Superfund Site: Served as Project Manager and Principal Hydrogeologist on hydrogeologic investigation in support of remedial design and remedial construction activities. Designed groundwater monitoring network consisting of 33 wells ranging in depth from 100 to 500 feet. Designed a groundwater extraction system consisting of four high volume and three low volume pumping wells as well as a pulse-pumping sequence to optimize plume containment and recovery.

  Designed and supervised an investigation program consisting of exploratory drilling, surface and downhole geophysics, onsite analysis with gas chromatograph, long-term water level monitoring, and aquifer testing. Designed and implemented an aquifer testing program consisting of two 48-hour pumping tests, three 6-hour pumping tests, and eight 100-minute pumping tests. Supervised and evaluated prove-out of extraction well network. Prepared deliverables including Work Plan, QA/QC Plan, Health and Safety Plan, Unsaturated Zone Investigation Report, Saturated Zone Investigation Report, and portions of Remedial Design Plan. Was responsible for a project budget of $2.1 million.

• United Chemical Technologies, CERCLA Site: Served as Project Coordinator. Was responsible for effecting a smooth transition during INTEX Environmental's takeover of site remediation activities. Project included demolition, decontamination, and closure of a portion of a chemical factory damaged by a chemical explosion and fire.

• Dixon Ticonderoga Co., RCRA Site: Served as Project Manager on corrective action of a closed RCRA unit on an active industrial site. Served as Project Manager on all phases from negotiation of consent order through RI/FS, RD/RA, and into operation and maintenance of remediation system. Was responsible for a project budget of $275,000.

• Liquid Carbonic Corp., Lagoon Closures: Served as Project Manager on the closure of five calcium hydroxide lagoons. Project included pre-closure dewatering and erosion/sedimentation design, dewatering, excavation, and off-site removal of approximately 75,000 tons of calcium hydroxide. Project also included preparation of local and State permit applications for lagoon closure. Was responsible for a project budget of $2.2 million.

• Tire Re-Treading Facility, New Jersey: Served as Senior Project Manager during preliminary assessment, RI/FS, remedial design, and remedial action phases. The site had numerous contaminant sources including metals, contaminated soils, dissolved and free phase petroleum contaminated groundwater, and waste solvent contaminated soil. Remedial action included installation of a cap over metal contaminated soil, free product recovery from the water table surface, and pump-and-treat of dissolved phase product using a bioreactor. Responsible for a present budget of $355,000 with an additional $275,000 for on-going remedial activities.

• Hilltown Township Water & Sewer Authority: Principal Hydrogeologist in the development and startup of a three well water supply system. Tasks included fracture trace analysis for well location, well logging and drilling contractor coordination, stepped discharge and continuous rate pumping tests and aquifer analysis.

KEY PROJECT EXPERIENCE:

• Twenty-nine years experience in environmental engineering and management including 15 years with the U.S. Public Health Service and the U.S. EPA.

• Developed and implemented plans to conduct bench and pilot scale treatability studies to assess the effectiveness of bioremediation, ultraviolet radiation/oxidation, incineration, thermal desorption, solidification/stabilization, air stripping, carbon absorption, and other evolving technologies.

• Conducted pilot scale studies for soil washing and UV/Oxidation of soil at a U.S. EPA Superfund site containing a pesticides blending and repackaging facility in Bakersfield, CA. Results used to design a field-scale treatability study onsite to demonstrate effectiveness of the technology in a removal action. The field-scale operation effectively removed and destroyed the contaminants in approximately 100 cubic yards of highly contaminated soil to the required clean-up level.

• Conducted a pilot scale treatability study to evaluate passive composting as a treatment alternative for the remediation of creosote-contaminated soil at a U.S EPA Superfund site containing a wood-treating facility in Federalsburg, MD. Approximately 10 cubic yards of contaminated soil was treated in the pilot-scale compost beds. The pilot-scale results were scaled up to treat 7,000 cubic yards of creosote-contaminated soil onsite.

• Conducted an evaluation of the extent of contamination of metal plating waste on a 11-acre U.S. EPA Superfund site in Olean, NY, using in-situ X-Ray Florescence analysis. The results were used to calculate the volume of soil requiring disposal or treatment. A Final Technical Report was prepared defining the site characteristics, estimates of contaminated soil volumes, and recommendations for removal/remediation actions.

• Evaluated eight potential alternatives for the remediation of contaminated soil at wood treating operations for presentation at a technology transfer seminar for U.S. EPA On-Site Coordinators. Technical documents were prepared for distribution at the seminar and a videotape was made of the proceedings.

• Evaluated potential alternatives for the remediation of contaminated groundwater from a "pump-and-treat" well field at a U.S. EPA Superfund site containing a wood treating operation in Butte, MT. Ultraviolet radiation/Ozone treatment and Activated Carbon treatment alternatives reviewed and bench scale testing conducted. Based on the results, carbon treatment was selected. Prepared conceptual design and specifications for a 500 gpm plant including the support buildings and utilities. Provided technical consulting and construction oversight during the construction of the facility. Supervised start-up operations of the facility and prepared operator manuals.

• Designed and installed shallow aquifer pump-and-treat system consisting of granular activated carbon treatment system and surface water discharge at a Superfund site in Deer Lake, PA, to remediate industrial waste lagoon leachate. Pumping cycle was integrated with onsite production well to intercept the contamination before the plume migrated to a Class A receiving stream. Project required extensive coordination with U.S. EPA site coordinator. Currently supervising operation of the system.

• Managed remediation of leaks and discharge from process solvent tanks and remediation of contaminated subsurface soil (soil concentrations ranged from 10 mg/kg to 1000 mg/kg) at a NJDEP ISRA Site in Newark, NJ. Performed alternative analysis and determined the cost-effective remedy to be soil vapor extraction. Designed and installed a combination well point and lateral extraction system underneath an existing concrete floored building. Sized and installed a 750 scfm extraction blower and 3,000-pound vapor phase carbon absorption module. Installed and operated system, obtaining required State and local air emission permits. Currently supervising operation of the system.
