Ms. Hartshorne’s qualifications include management, interpretation, and presentation of data generated by small and large multi-task projects. She has performed and managed more than 500 environmental assessments, remedial investigations, and landfill investigations in Arizona and other states. She has extensive experience in Phase I and II environmental site assessments and preparation of Stormwater Pollution Prevention Plans (SWPPPS) for industrial, commercial, and agricultural sites and remedial activities at hazardous and non-hazardous project sites. This includes historical and regulatory research, collection of soil and groundwater samples, supervision of subcontractors, health and safety compliance, data management, interpretation of laboratory analytical results, remediation oversight, technical report preparation, and quality assurance/quality control.

She is certified in accordance with federal Asbestos Hazard Emergency Response Act (AHERA) regulations to conduct inspections and provide oversight of asbestos abatement projects. This includes collection of bulk samples of suspect asbestos-containing materials (ACMs) for Comprehensive Asbestos Surveys of residential, commercial, and other structures, documentation and air sampling during abatement activities, and technical reporting. She is also certified by the Environmental Protection Agency (EPA) to perform sampling and risk assessment of lead-based paint in residences and other structures.

Her experience in landfill investigations includes waste characterization investigations, preparation of landfill operations plans, Aquifer Protection Permit (APP) documents, and solid waste facility plans, and performing landfill gas monitoring and Tier 2 landfill investigations.

The following is a partial listing of representative projects:

• Performed numerous Phase I and Phase II environmental site assessments (ESAs) and asbestos surveys for the City of Phoenix, City of Chandler, the City of Tucson, and Pima County for to evaluate risks associated with acquisition of all or portions of commercial, residential, agricultural, and vacant parcels for street construction, urban renewal, and other types of projects. Performed site reconnaissances, extensive history searches, and regulatory records reviews. Prepared and reviewed technical reports. Phase II ESA tasks included excavations at a former railroad yard, collection of soil samples, and oversight during removal of various solid and hazardous waste materials from a property. Asbestos surveys and abatement oversight were performed at properties prior to demolition of structures.
   
• Performed an extensive file and historical aerial photograph review of former and current aboveground and underground storage tank (UST) systems and other issues of potential environmental concern within the future Automatic People Mover Phase I Project Site Study Area at Sky Harbor International Airport for the City of Phoenix Aviation Department. Prepared a report documenting each of the tanks, other features, and environmental issues identified, and the potential concerns associated with each feature and issue.
   
• Performed pesticide investigations and a UST closure for Arizona State Land Department and Arizona Department of Administration at several inactive agricultural airstrips. Tasks performed included review of lease records and historical aerial photographs, coordination of archaeological surveys, collection of surface and subsurface samples in areas of concern and at random locations, interpretation and preparation of technical reports, preparation of Remedial Action Plans and subcontractor specifications, and oversight and documentation of remedial activities.
   
• Performed an Environmental Baseline Survey of a portion of the proposed alignment for the Yuma Area Service Highway for Arizona Department of Transportation. The site portion of the proposed alignment extends approximately nine miles across a vacant portion of the Barry M. Goldwater Range (BMGR) east of Yuma. Because no vehicles were allowed in the BMGR, SCS performed an aerial reconnaissance of the area by flying over the route and adjoining areas in a small plane, and then performed a site reconnaissance walking through selected areas of the site. Other tasks performed for this project were a regulatory database search interviews, review of previous reports, and preparation of a report.
   
• Managed and performed an environmental assessment of the El Campo Tire property, which was under consideration for acquisition by the City of Tucson under the EPA Brownfields program. The assessment included investigation of contamination associated with off-site USTs, soil staining near an automotive maintenance area and a former salvage yard area, and closure and assessment of on-site USTs. A Sampling and Analysis Plan was prepared and submitted to EPA for review and approval. The project involved a geophysical survey, excavation of exploratory test pits, drilling of soil borings, collection and analysis of soil samples, data validation of laboratory reports, and preparation of technical reports.
   
• Managed and performed an investigation of the proposed Arroyo Chico stormwater detention basin area for the City of Tucson and Pima County. Phases of the investigation included collection of surface soil samples, drilling and sampling of soil borings, percolation testing, installation and sampling of groundwater monitoring wells, sampling of surface water, long-term continuous monitoring of groundwater levels, groundwater modeling, and preparation of technical reports. Coordinated different phases of the investigation with subcontractors and County and City personnel. Prepared a final technical report that encompassed all phases of the investigation.
   
• Performed closure investigations for the west side of the Los Reales Landfill for the City of Tucson, including extensive file review and historical research; installation and sampling of groundwater monitoring wells; excavation of numerous test pits; oversight of geotechnical borings, geophysical surveys, and soil vapor investigations; soil vapor extraction system pilot testing; and preparation of technical reports. Managed and performed excavation and test boring investigations to evaluate a former industrial waste burial area for proposed clean closure. Prepared a detailed Site Characterization Report for work performed to date and a Remedial Action Plan for the clean closure area.
   
• Performed Site Characterization and Remediation Oversight of buried aluminum dross deposits within a housing community near Tucson. Tasks performed included historical research, geophysical surveys, soil logging and direct-push soil probes sampling, interpretation of laboratory analytical results of soil and dross samples, waste characterization, oversight of remediation activities, and reporting of findings. Investigation and remedial methods were selected and coordinated to minimize disruption to surveyed areas and maintain favorable relations with homeowners.
   
• Performed separator/sump closure investigations and assisted with extensive asbestos inspections during assessment and remedial projects associated with the redevelopment of industrial areas for Maricopa County’s Criminal Justice Facilities Development Department. Historical occupants of the redeveloped areas included a railroad freight depot, a bakery, a milk and ice cream processing plant, and various commercial properties.
   
• Performed Phase I environmental assessments of approximately 20 parcels within the Chase Field (formerly Bank One Ballpark) project area in Phoenix. Assessments included extensive historical research and compilation of findings, management of large amounts of data, review and summarization of groundwater contamination issues in that portion of the East Washington WQARF area, and preparation of technical reports. Also performed Phase II investigations for historical features of concern, including collection of soil samples, and oversight of geophysical surveys, soil vapor surveys, soil borings, and excavations.
   
• Implementation of NSPS Tier 2 landfill investigations in Arizona, Montana, Ohio, Missouri, and California. Tasks performed included planning and completing field programs, collection of landfill gas (LFG) samples from gridded landfill surface locations and a landfill gas collection system, and evaluation of analytical laboratory results.
   
• Managed and performed closure of three USTs found at a residential development during construction activities. The closure and Site Characterization activities were initiated and performed under a short time frame so as to allow construction to continue with as little delay as possible. Soil was excavated to meet Arizona residential soil remediation levels.
   
• Performed an investigation of the former location of three USTs at a facility in Tucson.
