Dredged Material Analysis

Dredged Material Analysis

 

Our toxicology labs have extensive experience developing and conducting assessments of freshwater, estuarine, and marine sediments and dredged materials.  Our laboratories have specifically designed flow through testing systems to support both freshwater and marine bio-accumulation analyses.  We have supported of a diverse array of projects across the United States, Canada, and throughout the Pacific Rim.  Such projects have ranged in scope from small-scale one-time local assessments, to projects involving intensive evaluations of 200+ sediment composites, to long-term 15+ year monitoring programs.

  • Tier III solid-phase and elutriate toxicity and bio-accumulation testing in support of USEPA/USACOE dredged material evaluation for ocean disposal (Ocean Testing Manual) or discharge in waters of the US (Inland Testing Manual)
  • Porewater analysis
  • Sediment-water Interface testing
  • Plume and sediment-flux studies
  • Confined disposal facility effluent evaluations
  • Toxicity and bio-accumulation testing in support of USEPA/USACOE Great Lakes dredged material evaluation
