The Geosyntec Family of Companies announces the promotion of 17 individuals to the position of Senior Principal. Each of these new Senior Principals has made significant contributions to delivering outstanding projects to first-class clients, developing strong relationships with those clients, building our practices, leveraging their own expertise and experience of their colleagues, recruiting outstanding staff, and working collaboratively with their coworkers.
Dan LaPorte (Ontario) recently joined Geosyntec Consultants as a principal hydrogeochemist. He has more than 15 years of experience as a subject matter expert in hydrogeological and geochemical characterization, predictive water quality modelling, environmental monitoring programs, and site investigations. In particular, Dan's work has focused on hydrogeological and geochemical investigations within the mining sector, waste management, and urban development industries, in Canada and abroad.
Dan LaPorte is a Senior Principal Hydrogeochemist based in Ontario with more than 11 years of experience focused on characterizing acid mine drainage and metal leaching and managing mine waste and site water.
Geosyntec practitioners rank among the world's top professionals in providing site assessment and remediation services at a wide range of impacted sites using innovative technologies and solutions that consistently advance the state of the practice. Through our use of innovative technologies and solutions, we provide our public and private sector clients with a wide array of services to address their toughest challenges. Our contaminated site practitioners guide our clients through a specialized remediation plan, consult on regulatory strategies, and develop a comprehensive cleanup approach. We can address numerous types of media, including contaminated soils, sediments, and groundwater. Advancing the State of the Practice Geosyntec's practitioners are pioneers in site assessment and remediation. Our senior practitioners have developed and authored guidance material and courses for local, state, and national agencies and associations on remediation techniques and technologies. Working with the Interstate Technical Regulatory Council, Geosyntec practitioners taught a training course on vapor intrusion, including mitigation options for the development of vapor-impacted brownfield sites. Geosyntec practitioners also wrote the guidance document on evaluating, optimizing, or ending post-closure care at impacted sites, including brownfield sites, and developed a patented approach for sub-slab vapor migration mitigation allowing residential, commercial, and industrial development on sites impacted by vapor intrusion. Our specialists routinely collaborate with prominent national researchers from academia and government agencies to provide innovative and defensible strategies for sites with contaminated sediments. For example, we collaborated with the United States Geological Survey (USGS) to remediate chlorinated solvent-contaminated marsh sediments by applying a bioreactive mat system embedded with a dehalogenating microbial consortium, a technology Geosyntec helped develop. This project and partnership earned our client recognition as a finalist for the Service to America Medal awarded by the Partnership for Public Service. Through a collaborative research project with the University of Florida, Geosyntec professionals helped develop the FLUCL software package for the Florida Department of Environmental Protection. This software is used to calculate exposure point concentration statistics in risk assessment and was the first of its kind to contain algorithms for censored datasets. FLUCL has received endorsements from several United States Environmental Protection Agency regions and the California Environmental Protection Agency. Geosyntec scientists also pioneered the use of genetic molecular tools to characterize microbes in environmental media and are engaged in applied research and development with top academic institutions around the world, including the University of Toronto, Cornell University, and the Georgia Institute of Technology.
Our clients understand environmental and occupational safety and health risk management is a vital component of maintaining overall operational excellence. Geosyntec's environmental management team builds compliance solutions, distinguishes between potential and actual environmental risks, and develops strategies to decrease energy and water utilization. Environmental and health & safety (EH&S) management system support services benefit our private and public sector clients who are committed to achieving high standards of EH&S performance and compliance. We develop documented management systems that allow our clients to identify, prioritize, and manage more efficiently the potential EH&S risks associated with their operations using a plan, do, check, act framework to ensure continuous program improvement. With a diverse portfolio of services, Geosyntec improves public and private sector clients' environmental and health and safety performance; manage risk; and reduce environmental liabilities consistent with their financial and stewardship goals. Our compliance, permitting, and auditing specialists have technical expertise across a broad range of disciplines. Accordingly, we are able to help our clients by proactively identifying compliance obligations and opportunities to improve their compliance record. Geosyntec practitioners specialize in solving complex challenges of occupational safety and industrial hygiene that affect workplace operations, staff comfort and productivity, or occupant health. Addressing such challenges involves the anticipation, recognition, evaluation, and control of known risks and emerging hazards in the workplace. Our practitioners conduct assessments using the sound scientific principles and practices of industrial hygiene, public health, and toxicology. We provide comprehensive Process Safety Management (PSM) and Risk Management Program (RMP) services to meet our clients' needs as they relate to the Occupational Safety and Health Administration's (OSHA) 29 CFR 1910.119 PSM Standard and the Environmental Protection Agency's (EPA) 40 CFR Part 68 RMP. The standards require the development and implementation of a system of procedures aimed at preventing accidental releases of hazardous chemicals from subject processes. All levels of an organization can benefit from our assistance in managing the daily aspects of its operations through development of environmental management systems, compliance programs and procedures, and regulatory research and applicability assessments. We accomplish this by implementing tools in a plan-do-check-act framework to ensure continuous program improvement.
