    Aerospace Experience

    Active Aerospace Client, Folsom, CA

    Project Manager

    Site wide vapor intrusion investigation. The project included collection of over 300 indoor air samples across 30+ occupied buildings at the Site. Timothy served as the team project manager maintaining good relations with client project management staff, plant staff, regulators and offsite stakeholders. He provided management of all onsite activities. Following the initial data collection, conceptual site models were developed for each of the buildings with potential vapor intrusion issues across multiple operable units at various stages of investigation and/ or remedy implementation.

    Remediation Experience

    Former Witco Facility, Lynnwood, CA

    Project Manager

    Field investigation of a former chemical plant. The investigation included characterization of mobile light non-aqueous phase liquids (LNAPL) in groundwater and the extent of polychlorinated biphenyls (PCBs) in soil.

    Caltrans Maintenance Station, Torrance, CA

    Case Manager

    Investigation of this LNAPL impacted site. The scope of work included characterization of the extent of mobile LNAPL at the Site by testing the fluid saturation level of soil cores. The LNAPL recoverability was estimated by performing an LNAPL bail down test. The information was used to create a conceptual site model and remedial cost estimate for the project.

    Former Manufactured Gas Plant, Porterville, CA

    Project Manager

    The former manufactured gas plant site was impacted by residual lamp black material from former operations. Work included development of a work plan, implementation of a field sampling plan, baseline risk evaluation, and reporting.

    Caltrans Maintenance Station, Santa Cruz, CA

    Case Manager

    Soil and groundwater investigation at a former UST Site. Activities at the site included soil boring and monitoring well installation, groundwater monitoring, and reporting. Timothy was responsible for the management of field staff and subcontractors.

    Caltrans Maintenance Station, Sonora, CA

    Case Manager

    Served as the case manager for installation of soil borings, remediation wells, and monitoring wells. The scope included characterization of a MTBE groundwater plume and a remedial pilot test using enhanced bioremediation with Waterloo Emitters. Managed the well installation, deployment of the pilot test materials, groundwater monitoring and reporting.

    Lincoln Center Environmental Remediation Trust, Stockton, CA

    The Lincoln Center is a commercial shopping area being remediated for impacted soil, soil-gas, and groundwater contamination of tetrachloroethene and associated degradation products from a dry-cleaning solvent release. Managed the decommissioning of an SVE and air sparge remediation system at this site. Responsibilities included scope and work plan development, permitting, subcontractor management, financial management, staff management and reporting.

    Former Bulk Fuel Storage Terminal, Spartanburg, SC

    Field Manager

    Served as the field manager for operation of a vacuum enhanced groundwater extraction and treatment system and was the primary author of groundwater recovery system and groundwater monitoring reports. Developed a conceptual site model and monitored a natural attenuation plan for the residual source areas and developed a work plan for additional site characterization. Managed field activities for high resolution site characterization of a groundwater plume utilizing a groundwater profiler, stream piezometers, and membrane interface probe (MIP).

    Active Coal/Natural Gas Power Plan, Bremo Bluff, VA

    Project Manager

    Served as project manager for installation of a groundwater monitoring well network and aquifer testing in accordance with the groundwater monitoring plan. Developed a conceptual site groundwater model for the client for the syncline formation underlying the site.

    Former Bulk Fuel Storage Terminal, Greensboro, NC

    Onsite Manager

    Onsite manager for installation of investigative borings and installation of an electro thermal dynamic stripping process (ETDSP) extraction system. Responsible for ensuring installation of electrodes, extraction wells, and monitoring wells that met specifications.
