Mr. Bradley Johnston, P.G. provides the SCS Arizona office with more than 14 years of experience in geological and environmental investigation and remediation. He is responsible for technical and administrative management of all phases of project work, including work plans and specifications; field work; research; data analysis; preparation and review of reports; budgeting; client contact; business development; and quality control.

Mr. Johnston has managed and performed over 500 environmental projects in Arizona, California, Colorado, Nevada, Florida, Louisiana, Texas, and New Mexico. These projects include site characterizations, sampling programs, and monitoring at municipal solid waste landfills and illegal disposal sites to assess the nature and extent of waste and local hydrogeological conditions. These investigations have included soil and waste sampling; installation and monitoring of landfill gas probes; air monitoring to protect drilling crews and evaluate the state of decomposition of waste material; and development and implementation of closure plans. He has also developed training programs for management of hazardous wastes in the solid waste system by performing evaluations of municipal solid waste collection procedures and landfill operations procedures. A partial listing of representative projects includes:

* Managed Phase I assessments, Phase II investigations, and remediation of the Chase Field (formerly Bank One Ballpark) stadium site in downtown Phoenix. The site consisted of a 10-block area occupied primarily by food warehouses; past uses included vehicle maintenance, manufacturing, and other industrial activities. Phase I investigations included historical research to the mid 1800s; archaeological and architectural evaluations; regulatory research and liaison; and preparation of 23 Phase I reports. Phase II investigations included asbestos inspections; soil borings; soil vapor and geophysical surveys; groundwater monitoring; and environmental and archaeological trenching. Remediation activities included asbestos abatement and UST and drywell investigation and removal. Project management involved emergency response to construction issues, extensive client and tenant liaison, and coordination of schedules and activities with subcontractors and other contractors, and attendance and presentations at public/regulatory meetings.

* Assisted with design and construction of soil bioremediation facility for a large coppers mine in northwestern Arizona. Analyzed waste stream characteristics for treatability; evaluated the need and low-cost alternatives for bioenhancement; developed standard operating procedures for waste stream characterization sampling, preparation, and treatment verification sampling; and met with operators of facility to provide input for more efficient facility operation.

* Managed and performed Phase I and Phase II investigations of landfills within the proposed City of Phoenix Rio Salado Habitat Restoration and Redevelopment Area. Included historical research, on-site inspections, and regulatory evaluation of over 15 landfill areas along a 6-mile stretch of the Salt River. Geophysical surveys, test pit and soil boring investigations, landfill gas evaluations, and groundwater monitoring well installation and monitoring are ongoing.

* Managed the characterization of an historical landfill located on the Phoenix-Goodyear Airport. Included historical research, regulatory analysis of closure alternatives, coordination of field activities with airport operations personnel, test pit evaluation of cover conditions and waste types and extent, and surveying of landfill boundaries.

* Development of quality control/quality assurance program for management of hazardous wastes encountered on collection routes and at landfills for the City of Jacksonville, Florida. Included in-depth analysis of landfill and collection system operations and development of a multi-level training course designed to enable workers and managers to identify and handle hazardous wastes in compliance with applicable regulations.

* Managed site characterization and remediation oversight of buried aluminum dross deposits within a housing community near Tucson, Arizona. Aluminum dross (a powdery, heavy metal containing waste generated by aircraft salvage operations) was dumped into dry washes in the vicinity of land which was later developed for housing, a public park, and an elementary school. Investigation methods and activities were selected and coordinated to minimize disruption to surveyed areas and maintain favorable relations with homeowners. SCS personnel also participated and supported municipal personnel in two televised newscasts and a public hearing.

* Taught worker health and safety training for asbestos in landfills. Provided workers with examples and procedures for identification of asbestos, explained health effects, and recommended procedures to minimize potential exposure.

* Drilling, logging, completion and sampling of groundwater monitoring wells, vadose zone wells, soil borings and gas probe installations for the purpose of defining contamination plumes and monitoring landfill gas levels.

* Performed field investigation at the Roosevelt and Tonto Basin Landfills in Gila County, Arizona. The tasks were performed in preparation for closure of the sites in accordance with ADEQ Aquifer Protection Permitting requirements.

* Performed site characterization and remedial action planning at contaminated sites lying on the route of the East Papago-Sky Harbor-Hohokam Freeway in Phoenix, Arizona. The investigation involved numerous landfills, numerous former gasoline stations, industrial properties, and other potentially contaminated site.

* Performed site characterization and provided landfill excavation oversight services at the Paradise Park disposal area in Phoenix, Arizona. Tasks performed included a site investigation to characterize and evaluate the lateral and vertical extent of waste materials, collection of soil and landfill gas samples, laboratory analysis, and report preparation. Additionally, provided oversight services during excavation and removal of the landfill.

* Performed health and safety oversight during landfill excavation for construction of the Rio Salado Parkway in the City of Tempe, Arizona. Tasks performed included developing a health and safety plan, training field personnel, overseeing landfill excavation activities, collecting verification soil samples for laboratory analysis, and preparing a report to document project activities.

* Drilling, logging, completion and sampling of groundwater monitoring wells, vadose zone wells, soil borings and gas probe installations for the purpose of defining contamination plumes and monitoring landfill gas levels.

* Performed NPDES applicability study for Mervyns distribution centers in California, Utah, and Texas. Tasks performed included reviewing stormwater discharge systems, site activities, and regulatory requirements. A report was prepared to present the findings and recommendations of the study.

* Performed and provided technical support for registration and permitting of industrial drywells, which are subject to Aquifer Protection Permit (APP) regulations. Tasks associated with registration and permitting included characterization of contamination; remediation oversight; evaluation of site drainage patterns; characterization of discharge; and designation of a Best Available Demonstrated Control Technology (BADCT).

* Mr. Johnston managed a Site Characterization of buried aluminum dross deposits within a housing community in Tucson, Arizona for Mr. Fran LaSala of the City of Tucson Office of Environmental Management. Following historical aerial photograph review and preparation of a site-specific health and safety plan, a geophysical survey was performed to identify buried dross deposits. Extensive soil sampling and logging was then performed using direct-push soil probes mounted on a small all-terrain vehicle. Following analysis and mapping of investigation results, remedial alternatives were analyzed and selected, and remediation bid specifications were prepared and implemented. Investigation and remediation methods were selected and coordinated to minimize disruption to surveyed areas and maintain favorable relations with homeowners and press. Mr. Johnston directed all technical and administrative aspects of this project, and participated in two televised newscasts and a public hearing in support of Mr. LaSala and Ms. Karen Masbruch of COT OEM.

* Mr. Johnston managed the Phase II Environmental Investigation of the Arroyo Chico Multi-Use Project for Mr. David Barraza of the City of Tucson Office of Environmental Management. This subject of this investigation was a proposed stormwater detention basin system that was located adjacent to a Tucson WQARF site with documented soil and groundwater contamination. Investigation activities included installation and sampling of nested groundwater wells, groundwater modeling, risk assessment screening, percolation testing, and soil sampling. Neighborhood representatives were concerned that the proposed detention basins would influence the distribution of PCE and petroleum groundwater contamination from the WQARF site. Mr. Johnston directed all administrative and most technical aspects of this project, and he attended neighborhood task force meetings and a City Council hearing to provide technical support to City of Tucson and Pima County staff for explanation of investigation methodology, contamination distribution, and potential risks.

Mr. Johnston has also been involved in hazardous waste management, including supervision of spill cleanup operations, asbestos abatement projects, transportation documentation of hazardous wastes, and permitting with state and local agencies.

Mr. Johnston is certified in accordance with federal Asbestos Hazard Emergency Response Act (AHERA) regulations to conduct inspections, evaluate risks, and develop management plans for asbestos-containing materials (ACMs). He has performed inspections and collected bulk samples of suspect ACMs in residential and commercial buildings; prepared abatement specifications for removal of ACMs; developed operations and maintenance programs for ACMs remaining in place; and provided abatement and demolition documentation services. A partial listing of representative projects includes:
