Contaminated Sediment Management

Contaminated sediment management is a complex issue that encompasses initial site assessment, remediation and restoration, monitoring and 5-year reviews, and determination of potential natural resource damages. Adding to the technical complexity is the need to interface with multiple regulatory agencies while addressing legal requirements, competing public interests, and constraints of cost and time.

NewFields’ sediment management specialty provides clients with strategic solutions based on focused, cost-effective technical approaches that are compliant with regulatory requirements. We draw upon multidisciplinary resources: (1) our state of the art analytical laboratory for risk based detection limits and source identification; (2) experienced risk assessors focused on managing uncertainties; (3) our ecotoxicity laboratory for evaluating site-specific effects; and (4) GIS specialists to dynamically manage the complex data developed during the assessment process. Overarching these technical capabilities are consulting specialists who integrate the multiple lines of evidence to best direct the sediment management process.

NewFields scientists have supported Fortune 100 companies in assessing contaminated sediment from rivers and creeks impacted by hundreds of years of industrial changes. We have represented clients on several EPA sediment “megasites,” defended clients in natural resource damage claims, and conducted hundreds of CERLCA/RCRA and state-led investigations.
