Developing Sediment Remediation Goals at Superfund Sites Based on Pore Water for the Protection of Benthic Organisms from Direct Toxicity to Non-ionic Organic Contaminants (PUBLISHED REPORT)
This document contains a methodology for developing interstitial water remediation goals (IWRGs) for nonionic organic pollutants (toxicants) in sediments for the protection of benthic organisms. The document provides the basis for using the final chronic values (FCVs) from EPA’s...
Can interpreting sediment toxicity tests a mega sites benefit from novel approaches to normalization to address batching of tests? (PRESENTATION)
Sediment toxicity tests are a key tool used in Ecological Risk Assessments for contaminated sediment sites. Interpreting test results and defining toxicity is often a challenge. This is particularly true at mega sites where the testing regime is large, and by necessity performed ...
Final ecosystem goods and services enhance societal relevance of contaminated-site remediation (PRESENTATION)
Background/Question/Methods Exposure to environmental stressors can adversely affect both human health and ecological receptors and impacts on the latter influence the community's overall vulnerability. Risk assessment guidance promotes conceptual site models to integrate multip...

Contaminated Sediments/Remedy Effectiveness 3.6.1.3 (PRESENTATION)
The main objective of this research effort is to provide stakeholders with biological, chemical, and physical tools, indicators and approaches to more effectively assess and manage contaminated sites, under the Great Lakes Legacy Act (GLLA), Great Lakes Restoration Initiative (GL...
Assessing remediation of contaminated sediments using multiple biological endpoints: sediment toxicity, food web tissue contamination, biotic condition and DNA damage. (PRESENTATION)
The Ottawa River is a component of the Maumee River Area of Concern (AOC) as defined by the International Joint Commission&rsquo;s Great Lakes Water Quality Agreement. A sediment remediation project took place in the lower 14.2 km of the river where urban and industrial activitie...
Sediment Toxicity Testing (BOOK CHAPTER)
Sediment toxicity testing has become a fundamental component of regulatory frameworks for assessing the risks posed by contaminated sediments and for development of chemical sediment quality guidelines. Over the past two decades, sediment toxicity testing methods have advanced co...
Deriving sediment Interstitial Water Remediation Goals (IWRGs) for the protection of benthic organisms from direct toxicity (PRESENTATION)
Background/Objectives. Passive sampling is becoming a frequently used measurement technique at Superfund sites with contaminated sediments. Passive sampling measures the concentrations of freely dissolved chemicals (Cfrees) in the sediment interstitial water. The freely dissol...
EPA’s Environmental Justice Research Roadmap and Interagency Efforts on Climate Justice (PRESENTATION)
Stressors associated with climate change are expected to be disproportionately greater for overburdened communities. This webinar will present activities of the Climate Impacts subcommittee of the Federal Interagency Working Group (IWG) on Stressors associated with climate chang...
Assessing the effects of legacy contaminants on egg and nestling survival of tree swallows in Great Lakes Areas of Concern (PRESENTATION)
Great Lakes Areas of Concern (AOCs) are affected by many stressors, some of which are environmental contaminants including PCBs, PBDEs, persistent organochlorine pesticides, dioxins, benzenes, and other chemicals. These toxicants can accumulate in aquatic biota and ultimately tra...
