ENVIRON engineers, ecologists and risk assessment specialists have extensive expertise with planning, implementation and oversight of investigation, assessment, remediation and restoration of ports and waterways challenged by concerns about navigation and contaminated sediments.
ENVIRON emphasizes the development of scientifically defensible, sediment quality guidelines (SQGs), sediment management goals, and achievable remediation performance standards. We use both screening-level and detailed assessment techniques to evaluate chemical, biological and habitat conditions and to identify possible issues affecting different management options. We use several investigation methods depending on waterway-specific conditions and the regulatory context, including sediment sampling and analysis, toxicity testing, benthic community and wildlife surveys, habitat suitability characterization, fish sampling, amphibian egg mass surveying, avian nest monitoring, sediment transport modeling and historical research.
Our engineers and remediation specialists use pre-remedy (baseline) risk assessments and remedy alternative analyses to help clients identify opportunities to control site remediation costs, improve the likelihood of project success, and develop effective long-term monitoring plans to demonstrate environmental improvement. We have substantial expertise in the application of several sediment management practices and technologies, including dredging, in-situ capping, solidification, stabilization, thermal treatment, upland disposal, and confined aquatic disposal.
