Principal Remediation Engineer/Project Manager
Relevant Experience and Distinguishing Qualifications
Principal remediation engineer/project manager with 30 years of
experience in environmental consulting engineering, waste
management, site assessment and remediation, water resources,
wastewater process engineering, compliance and expert witness
litigation support. He has directed, managed, and performed site
assessments, remedial investigations, feasibility studies, risk
assessments, remedial designs, and remedial system construction,
operation and maintenance, and remedial process optimization. Work
experience includes numerous Superfund, RCRA, LUST, and
voluntary cleanup program sites throughout the United States as well
as sites in South America, Latin America, and Puerto Rico. Significant
achievements are listed below.
• Managed many large, complex, high-visibility projects whose
performance was commended repeatedly by clients; reputation
and performance on these projects were key in winning $200
million, 10-year re-compete contract
• Saved clients and other parties approximately $20 million in
remedial investigation and construction costs by developing
innovative sampling and analysis programs and through peer
technical reviews of remedial designs
• Managed oversight of investigation, design, and construction
activities worth approximately $300 million
• Managed remedial investigation, design, and construction
activities worth approximately $10 million
• Successfully negotiated the scope of remedial investigation,
design, and construction activities at over 100 contaminated sites
in the U.S, South America, Latin America, and Puerto Rico.
