Geosyntec's human health and ecological risk assessment services identify the proper approach to remediate sites impacted by a wide variety of contaminants. Our risk assessment specialists work in conjunction with our remediation practitioners to develop site-specific solutions that achieve the needed levels of protection while optimizing financial commitments and operational practicalities for our clients. Our specialists also provide expert consultation and testimony on environmental exposure health issues for our legal clients. Through our technical specialists in biostatistics, epidemiology, information management, and contaminant fate and transport modeling and other specialized practitioners, we provide an exceptional quality of work that has become the envy of the industry.

Practice Specialties

We believe that there are substantial flexibilities that can be utilized and that, through the use of alternative, science-based approaches, risk assessment can be a powerful tool for site closure, redevelopment planning, and management of environmental liabilities. Through our specialization in the development of site-specific approaches, we are able to characterize risk and tailor our approach to address our client’s goals and objectives for compliance, financial management, and environmental stewardship. Our practitioners have expertise in addressing complex issues associated with multi-party or high-profile sites and integrating remediation and redevelopment plans with sensitive land use designs, such as residential neighborhoods, schools, recreational facilities, or wildlife habitats. 

Geosyntec also provides specialized applied toxicology services to address a variety of health issues related to exposure to chemicals like chlorinated solvents, pesticides and herbicides, PCBs, dioxins and furans, PAHs, MtBE, BTEX; physical agents like asbestos and radionuclides; and consumer and pharmaceutical products. Attorneys utilize our distinctive capabilities to support litigation involving toxic tort, workers compensation, and product liability.

As an example of our integrated application of our risk assessment capabilities, our practitioners used a detailed spatial analysis of soil sampling results to support the averaging of composite samples in estimating exposure point concentrations for use in a risk assessment of areas adjacent to a stormwater drainage channel. Our method saved the client more than $500,000 in investigation costs when compared to more traditional statistical approaches. The analysis also accelerated the implementation of remedial action at the site. 

Advancing the State of the Practice

We are helping shape the future of risk assessment through our applied research with colleagues in the academic, industrial, and regulatory sectors. For example, through a collaborative research project with the University of Florida, Geosyntec professionals assisted in the development of 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 U.S. Environmental Protection Agency (EPA) regions and the California EPA.
