Sediment Quality Assessments


sediment toxicity study

Sediment quality assessments are useful in determining sediment quality in receiving streams of whole effluents, previously impacted sites, and other contaminated areas. At GLEC we have the experienced staff, the equipment, and the resources necessary to conduct integrated sediment quality assessments by effectively evaluating benthic community structure, tissue and sediment chemistry, and sediment toxicity. GLEC is capable of, and experienced in conducting benthic surveys (qualitative and quantitative), Rapid Bioassessment Protocols (RBP), whole sediment / sediment porewater / elutriate toxicity testing, and sediment / tissue chemistry. GLEC staff have both depth and breadth of experience in: aquatic ecology, wetland ecolgy, fisheries ecology, invertebrate taxonomy and aquatic toxicology, and can effectively interpret either partial or complete sediment quality assessments. Further, GLEC has the equipment and facilities needed to perform intensive field and laboratory investigations.
