Anchor QEA has worked on some of the largest, most complex aquatic cleanup sites in North America. Working under federal and state programs, we have provided remedial solutions for long-abandoned legacy sites, fully active industrial operations, and undeveloped sites where activity is planned. Our engineers and scientists construct a conceptual site model to determine if, where, and how remedial measures may be warranted to reduce risk and/or liability.
Our staff have prepared many feasibility studies at contaminated sediment sites and have tools and experience designing, implementing, and monitoring remedial technologies. With this experience, our reputation with agencies and knowledge of regulations supports the selection of the most scientifically sound and cost-effective solutions.
Anchor QEA manages many of the largest and most complex sediment remediation projects in the United States and Canada. We have completed hundreds of remediation projects involving dredging, capping, enhanced natural recovery, nearshore confined disposal, confined aquatic disposal, treatment, and beneficial reuse of contaminated sediment.
Grasse River Sediment Remediation and Habitat Reconstruction
Historical industrial activities along the Grasse River in upstate New York released polychlorinated biphenyls (PCBs) that accumulated in more than 7 miles of the river’s sediments. These compounds can bioaccumulate up the food chain, which led to a fish advisory put in place for the Lower Grasse River due to elevated levels of PCBs in fish. Anchor QEA’ supported the successful completion of a 3-year-long remedial construction phase, which included dredging, capping, and habitat reconstruction.Learn More About This Project
Construction Management and Water Quality Monitoring
Anchor QEA helped carry out construction management and monitoring for Honeywell at the Lake Linden Area A Time-Critical Removal Action (TCRA) in Michigan, part of a Superfund site in the Great Lakes faced with elevated concentrations of various metals.Learn More About This Project
Sediment Remediation West Coast Shipyard
Anchor QEA supported pre-construction activities and the contractor selection process for a sediment remediation project at two active and adjacent shipyards.Learn More About This Project
Field Investigation and Remediation
Anchor QEA supported the field investigation and remediation of river sediment containing an apparent NAPL substance and PCBs.Learn More About This Project
Remedial Action Plan Development
Anchor QEA assisted with development of a comprehensive remedial action plan to address river sediments containing PCBs. We developed and evaluated remedial alternatives, including monitored natural recovery, activated carbon addition, capping, and dredging. We also developed mathematical models and assisted in the design and implementation of several sediment remediation pilot studies. We led a multi-disciplinary“Remedial Action Plan Development”Learn More About This Project
