Greg Gibbons (Illinois) and Anne Fitzpatrick (Washington) are featured in an article entitled "Geosyntec's Strong Sediment Remediation Practice Supports Years of Consistent Growth" in the Environmental Business Journal (EBJ) in Volume 30 Number 7&8, Fall 2017, pages 26-17.

Sediment Assessment and Remediation

Lakes, rivers, reservoirs, and marine environments, especially those in urban waterfront and coastal areas, often have contaminated sediment and surface water and stressed biota from decades of industrial and commercial activities. Sediment contamination can include metals, crude oil and refined petroleum compounds, polynuclear aromatic hydrocarbons (PAHs), pesticides, per- and polyfluoroalkyl substances (PFAS), and polychlorinated biphenyls (PCBs). Because contaminated sediment sites present complex challenges, site evaluation and cleanup are expensive and can take several years to implement, and the metrics for remedy effectiveness are not often well defined.

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.

Remedial Investigation/Feasibility Study at the Berry’s Creek Superfund Site, Bergen County, New Jersey

2026-04-02T15:50:52-06:00October 24th, 2009|Tags: , , |

The Berry's Creek Study Area (BCSA) is a sediment "Mega Site" located in Bergen County, New Jersey, just across the Hudson River from New York City. It is an urban mix of industrial, commercial and residential properties. Berry's Creek itself is a tidal tributary of the Hackensack River, and its watershed encompasses approximately 12 square miles of marshes. The watershed has been found to contain elevated levels of contaminants of potential concern (COPCs) that have migrated to the watershed from various point and non-point sources. A group of potentially responsible parties (BCSA Cooperating PRP Group, or Group) has formed to conduct an RI/FS at the site. In 2007, the Group selected Geosyntec to lead a team to develop and implement the three-phased RI/FS. Ultimately, the results of the RI/FS will be used by U.S. EPA to prepare a Record of Decision.
