Sediment can be a repository and potential reservoir for persistent and bioaccumulative organic and inorganic contaminants. Many of these contaminants can biomagnify in the food chain and may have a significant ecological and human health risk effect.
Sediment management decisions are often made within a complex regulatory arena. No single government agency is completely responsible for addressing the problem of contaminated sediments. More than 10 independent federal laws provide authority to address sediment quality issues to EPA, US Army Corps of Engineers (USACE), National Oceanic and Atmospheric Administration (NOAA), and other federal, state and tribal agencies.
Sites vary in their size and complexity. Our experience has proven that to successfully provide sediment testing support, projects require detailed pre-project scope definition, planning and execution. Sediment sites often involve more than one medium, including surface water, tissues, pore water, groundwater, and soils. These sites potentially involve multiple contaminants of concern from a variety of sources, geographic areas and ecological settings. Eurofins TestAmerica’s sediment program standards identify systematic laboratory procedures that address the complexities and challenges associated with sediment projects. These standards provide the technical framework for our sediment laboratories to deliver the highest levels of scientific and service performance in the environmental testing industry.
Eurofins TestAmerica has extensive experience providing chemical and physical testing services in support of sediment projects nationwide. These projects have been executed within various US EPA Regions, USACE Districts, as well as under various state and local governmental agencies. Guided by industry leading expertise and unmatched laboratory capacity, Eurofins TestAmerica’s goal is to generate analytical data that meets project specific data quality objectives, thereby facilitating appropriate sediment management decisions.
