CAREER SUMMARY
Ms. McMaster is a Senior Principal Scientist with over 20 years of experience ingroundwater remediation. She is currently managing director of Canadian andAustralian consulting operations. Ms. McMaster is a member of Geosyntec’s Board ofDirectors (2018-2020) and sits on several committees within Geosyntec. Ms. McMasteris the project director for several large multi-disciplinary teams for the design andimplementation of full-scale soil and groundwater remediation projects for
multinational clients in North America, Latin America and Australia. Her area ofexpertise includes source zone remediation of DNAPLs, monitored natural attenuation(MNA) and enhanced in situ bioremediation (EISB) of chlorinated solvents and otherrecalcitrant compounds. She is a technical lead for complex emerging contaminant
investigation for confidential clients. She is the project director for first full-scale
applications of innovative technologies for challenging sites, including partitioning
electron donors for TCE source treatment and self-sustaining treatment for active
remediation (STAR) for coal-tar impacted sites.

selected is Self-Sustaining Treatment for Active Remediation (STAR) which is an innovative insitu smoldering method which is cost-competitive to conventional technologies (ISS andexcavation). First full-scale field application of STAR. In addition to the soil remediation anddesign, Geosyntec is completing the long term groundwater remediation strategy for this site.
Including, an evaluated and interpreted sustainability of eight different remedial alternatives forthis large coal tar contaminated site, using SimaPro, a specialized Life Cycle Assessment
software package. This site is under New Jersey’s Licensed State Remediation Professional(LSRP) program.

Former Manufacturing Facility, Confidential Client, Los Angeles, CA. This project
involved serving as Project Director for a full-scale application of EISB, to treat TCE
and 1, 2-DCA in a multi-layer aquifer. Pilot results and comprehensive modelingassessments were used to develop the full scale design for the site. This remedy also
includes a natural attenuation component for parts of the site where remediation is
sufficient to contain the 1, 2-DCA.
Former Manufacturing Facility, Confidential Client, NJ. In this multi-disciplinary
team Ms. McMaster serves as a technical specialist for full-scale applications ofremedial options for a large dispersed PCE plume. The operating extraction, treatment
and re-injection system is ineffective at controlling vapor intrusion issues. Alternativestrategies are being evaluated as well as detailed off-site characterizations to understandsite conditions. A pilot test will be completed to evaluate EISB for an isolated hot spot.
Manufacturing Facility, DuPont, Deep Water, NJ. Development and application of anovel remedial options selection tool for ranking remedial alternatives. This project
involved the translating of the 14-Compartment Model into a spreadsheet tool toevaluate a complex site for a corrective measures study. This work is being expanded
to develop a tool that can be used by the DOD as a web-based evaluation tool forRPMs.
Manufacturing Facility, DuPont, Brazil. In this multi-disciplinary team Ms.
McMaster serves as a technical specialist for evaluating the performance success of afull-scale application of EISB to treat a complex plume of chlorinated ethanes.
Activities include review, technical oversight and providing guidance to in country
consultants and field staff. Additional site characterization is planned to further
understand the current site conditions.
Former Industrial Facility, Confidential Client, CA. This project involves developing
a combined remedy approach to treat a mixed VOC source zone. Ms. McMaster serves
as the Senior Scientist and is responsible for groundwater remediation activities. The

adaptive management strategy will involve sequential application of technologies
including enhanced in situ bioremediation and conventional containment. This project
involves working with a large multi-group team.
Former Industrial Facility, Confidential Client, CA. Project Manager for an enhanced
in situ bioaugmentation. This included using a passive in situ biobarrier (injection ofemulsified vegetable oil) to treat TCE and other chlorinated VOCs in several
groundwater plumes. The tests were one of the first successful applications ofemulsified oil and bioaugmentation. Pre-design evaluations required integration ofredevelopment. At one of the plumes a “No Further Remediation” approval wasobtained less than three years after amendment of edible oil. The other two sites wereexpanded to full scale (over more than 17,000 square feet of treatment area) and are
currently in progress. These applications were completed in a low permeability layer
and effectively demonstrated that the emulsified vegetable oil could be injected andsustained in the area for more than 18 months. This project involved working with alarge multi-group team.
Former Industrial Facility, Confidential Client, Greater Los Angeles, CA. ProjectManager for an enhanced in situ bioaugmentation using a passive in situ biobarrier(injection of emulsified vegetable oil) to treat TCE in groundwater. An in situ biobarrier
was created using subsurface well vaults for access due to site redevelopment. Thebarrier will be monitored for a three year period. The design allows for repeat
applications of electron donor if necessary.
Former Industrial Facility, North Eastern US. Project Scientist for the evaluation oftreatment of both hexavalent chromium and chromium ore process residue in soils andgroundwater using innovative remedial approaches. Tasks included developing a white
paper on speciation and developing remedial designs and treatability tests using
biological and chemical treatment approaches.
Aerospace Manufacturing Facility, Ontario, Canada. Project Director for installationand operation of a large EISB (> 100 gpm) recirculation system in fractured bedrock.
Including, ongoing site investigation, regulatory and public consultation support. The
EISB system aims to limit off-site migration of chlorinated solvents and reduce system
operation by promoting source reduction through the application of electron donors insuspected source areas.
Active Manufacturing Facility, Confidential Client, Bulle, Switzerland. Project
Scientist for the design and operation of an in situ passive EISB system to treat TCE
and associated dechlorination products.
