Geosyntec announces our 2026 class of Principals and Senior Principals. These individuals exemplify the values that define the firm: collaboration, inclusion, innovation, safety, and passion for excellence.
Jonathan Allen is a Senior Principal Scientist based in Tennessee with more than 18 years of experience focusing on water and natural resources.
The Geosyntec Family of Companies is pleased to announce the promotion of 24 individuals to the position of Principal. Each of these new 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 co-workers.
Jonathan Allen, CPESC, TN-QHP (Tennessee) presented "Sinkhole Policy and Analysis, Knox County, Tennessee," and Darrell Nicholas, PE and Dillon O'Donnell, PE (Tennessee) presented "Implementation of Flood Mitigation Measures in Karst Areas of Knox County, Tennessee" at the Tennessee Stormwater Association (TNSA) Conference at Montgomery Bell State Park in Burns, Tennessee on October 21, 2021.
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.
Geosyntec uses biological assessment and monitoring to create an accurate picture of the affected environment. Our services reliably evaluate the health of streams, rivers, lakes, and ocean environments. In addition, we can offer a less expensive alternative to complex chemical testing programs. Relying on deep experience, our team evaluates the ecological health of a given environment to show how organisms integrate the effects of varied stressors at your site over time. This means Geosyntec can characterize long-term ecological issues and understand the status of highly valued biological communities. By examining a variety of species, their life stages, their survival, and their health, Geosyntec deciphers complex relationships among habitats, bioregions, and ultimately, water and sediment quality. Geosyntec has experienced biologists who efficiently conduct fish and invertebrate collection for both site investigations and NPDES-permit compliance. We also partner with industry-leading laboratories to analyze samples, compile metric scores and data into a project database, and use geographic information system capabilities to define spatial relationships and ensure data consistency and comparability. Geosyntec's biological monitoring services include fish tissue collection for analysis of chemicals of concern; fish population and macroinvertebrate/plankton community studies; fish-kill investigations; and sediment infaunal invertebrate studies. We also conduct habitat inventories and assessments; sediment and water quality toxicity testing; ecological risk assessments; and Natural Resource Damage Assessments. Our practitioners compile environmental impact statements for compliance with National Environmental Policy Act requirements and consult with clients on Clean Water Act (CWA) Section 404 wetland permitting, Section 401 water quality certification, and threatened and endangered species surveys related to the Endangered Species Act (ESA) and Section 7 requirements. For more than a dozen clients, Geosyntec has monitored the concentrations of chemicals found in fish tissue over many years. Often, the fish community is exposed to chemicals via direct or indirect uptake from contaminated sediments. By monitoring the fish tissue concentrations over time, the effectiveness of an environmental remedy can be evaluated. Additionally, biota-sediment accumulation models can be developed and refined to support informed management decisions. This has been used for both active remedies (like dredging) and passive remedies (like MNR). These monitoring data provide our clients and the regulatory agencies with an accurate picture of the affected environment.
Geosyntec's engineers and scientists stand among the world's foremost experts in urban stormwater management. We are innovators who design best management practices to mitigate impacts to surface water quality, enhance water conservation strategies, and contribute to municipal water supplies. Our professionals develop and implement comprehensive water quality master plans and site-specific designs using green infrastructure concepts for long-term stormwater control. We also guide the development and design of construction, industrial, and municipal programs for National Pollutant Discharge Elimination System (NPDES) regulatory program compliance. We have evaluated the opportunities, constraints, effectiveness, and costs associated with a variety of low impact development and green-streets options and have provided conventional treatment control BMPs for maintaining water quality control. We provide end-to-end solutions for a wide variety of applications from proprietary cistern sizing and optimization modeling and water collection and pre-filtration strategies, to designs for filtration, treatment, and water distribution systems. Our water resources engineers specialize in surface-water and groundwater interactions, ecosystem restoration, multi-beneficial project development, hydromodification management, and erosion and sediment control. In addition, our practitioners have been instrumental in developing, publishing, and supporting numerous stormwater guidance and design manuals. Geosyntec professionals established and continue to contribute to the International Database on Urban Stormwater BMP Design and Performance. We frequently present state-of-the-practice training sessions and workshops on stormwater management, NPDES regulatory program requirements, erosion and sediment control technologies, and BMP performance and design.
Geosyntec's water and natural resources practice is a collaborative group of nationally recognized scientists and engineers dedicated to balancing built and natural environments. Their practice specialties represent many disciplines, including geomorphology, ecology, biology, statistics, construction management, computer science, and engineering. Our practitioners are at the forefront of policy analyses, regulatory compliance, and technology applications that promote sustainable water resources management and ecosystem restoration.
