Trusted Expertise in Sediment Testing
Sediments are a major source and sink of contaminants that can directly, or indirectly affect the food web and human health. Sites impacted by sediment contamination can be in various stages of remediation, restoration or redevelopment. Understanding current conditions and working with a capable testing partner through remediation and redevelopment is key to project success. SGS delivers trusted sediment testing services to support industries like environmental remediation, coastal engineering, offshore wind development, and more. Our network of 20+ labs, high capacity and ability to execute on large and complex projects is key to the success of your project, small or large. With decades of experience, advanced laboratories, and a team of skilled chemists, we provide reliable, timely results to help you navigate complex regulatory requirements and make confident decisions.

Solutions for Complex Projects
SGS understands the challenges posed by sediment matrices, such as high and varying levels of contamination, high moisture content, and frequently, ultra-trace analytical requirements. With PFAS in sediments emerging as another concern, SGS’ expertise in developing EPA 1633 for the US EPA is key in maintaining testing accuracy and precision. Our team offers tailored solutions, leveraging cutting-edge instrumentation and the resources of the global SGS network to deliver accurate, actionable data. Whether your project involves dredging evaluations, ecological risk assessments, or long-term monitoring, SGS has the expertise to support your goals.
