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.

Marsh Sediment Removal Action and Ecological Risk Assessment, Brunswick, Georgia

2026-05-28T07:20:03-06:00June 1st, 2014|Tags: , , , , |

The LCP Chemicals Site is among the most complex CERCLA remediation projects in U.S. EPA Region 4. Past site operations included petroleum refining, electric power generation, and paint and chemical manufacturing which resulted in contamination of soil and groundwater. The site is located adjacent to an ecologically-sensitive estuarine marsh. Contaminants include volatile organic compounds (VOCs), polynuclear aromatic hydrocarbons (PAHs), mercury, chromium, lead, and polychlorinated biphenyls (PCBs). Geosyntec was retained to provide lead engineering services for a CERCLA removal action and a remedial investigation/feasibility study (RI/FS).

Commercial manufacturers, specialty chemical firms, and industry and legal-sector clients often face a complicated mix of constituents at their sites. They need to understand the implications of cumulative exposures across multiple pathways, often for multiple populations. In addition, they may be facing uncertainties associated with emerging constituents, which are often not yet well understood.

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.

Wetland Delineation and Permitting

Geosyntec practitioners are leaders in the development and application of science-based methods and tools for wetland identification and delineation. By determining the existence, location boundaries, and physical size of a wetland area, we help clients establish whether water bodies within a project area meet criteria for regulation under specific local, state, and federal jurisdictions. In addition, we make recommendations as to the size or width of any buffers that may be needed to protect water quality or habitats. Our field investigations and surveys establish clearly marked wetland boundaries, comprehensive delineation maps with data collection points, and site-specific information such as soil survey results or species composition and dominance data. We also can assess whether created or replicated wetlands function effectively and then aid clients in the application of this information to future design plans. This can include an evaluation of pre-construction design criteria and monitoring protocols. Once a wetland delineation is complete, Geosyntec guides clients through the permitting application process as outlined in Section 401 or Section 404 of the Clean Water Act as well as the various state and regional laws governing water bodies throughout the United States.

Environmental Impact Studies

For more than 40 years, strict adherence to guidelines under the National Environmental Policy Act requires all federal agencies to consider the environmental impacts of a broad scope of proposed actions and decisions as well as to consider any reasonable alternatives to those actions. Geosyntec's engineers and scientists offer clients decades of experience in the development of comprehensive environmental impact statements (EIS) for actions requiring federal authorization or that are otherwise subject to federal control. We also prepare EIS as required by regulations at the state and regional level around the country. Our practitioners across multiple disciplines lead the development of EIS for clients within the U.S. Department of Defense, U.S. Customs and Border Protection, the Federal Bureau of Prisons, the U.S. Air Force, and the U.S. Army Corps of Engineers, to name just a few. Impact statements are submitted for public comment periods throughout the development process. In addition, we guide clients through the review and comment by officials with the U.S. Environmental Protection Agency before a final EIS and record of decision can be infused into a program or action. As we develop an EIS, we ensure our detailed analysis provides a discussion of any significant environmental impacts affecting a project as well as the purpose of and need for proposed actions. We then review reasonable alternatives, including a No Action alternative, which would allow agency officials to avoid or minimize adverse impacts or enhance the quality of the human environment. These full disclosure documents detail the process through which a federal project was developed and demonstrates compliance with other applicable environmental laws and executive orders.
