ITRC Strategies for Preventing and Managing Harmful Cyanobacteria Blooms (Two Part Series) - April 26 and 28, 2022. Cyanobacteria are microscopic, photosynthetic organisms that occur naturally in all aquatic systems but most often in freshwater systems. Under certain conditions, cyanobacteria can multiply and become very abundant, discoloring the water throughout a water body or accumulating at the surface. These occurrences are known as blooms. Cyanobacteria may produce potent toxins (cyanotoxins) that pose a threat to human health. They can also harm wildlife and domestic animals, aquatic ecosystems, and local economies by disrupting drinking water systems and source waters, recreational uses, commercial and recreational fishing, and property values. It is likely that continued population growth, land use change, increases in nutrient inputs to our waterways, and the warming climate will favor proliferation of these problematic species. Providing a range of practical approaches to minimize these blooms and their likely societal and wildlife effects is critical to our future vitality, health, and economic prosperity.

ITRC Bioavailability of Contaminants in Soil: Considerations for Human Health Risk Assessment - May 3, 2022, 1:00PM-3:15PM EDT (17:00-19:15 GMT). The basis for this training course is the ITRC guidance: Bioavailability of Contaminants in Soil: Considerations for Human Health Risk Assessment (BCS-1). This guidance describes the general concepts of the bioavailability of contaminants in soil, reviews the state of the science, and discusses how to incorporate bioavailability into the human health risk assessment process. The target audience for this guidance and training course are: project managers interested in decreasing uncertainty in the risk assessment which may lead to reduced remedial action costs, and risk assessors new to bioavailability or those who want additional confidence and training in the current methods and common practices for using bioavailability assessment to more accurately determine human health risk at a contaminated site. As a participant in this training you should learn to: apply the decision process to determine when a site-specific bioavailability assessment may be appropriate, use the ITRC Review Checklist to develop or review a risk assessment that includes soil bioavailability, consider factors that affect arsenic, lead and PAH bioavailability, select appropriate methods to evaluate soil bioavailability, and use tools to develop site-specific soil bioavailability estimates and incorporate them into human health risk assessment.

ITRC Integrated DNAPL Site Characterization - May 5, 2022, 1:00PM-3:15PM EDT (17:00-19:15 GMT) The Integrated DNAPL Site Characterization Team has synthesized the knowledge about dense non-aqueous phase liquid (DNAPL) site characterization and remediation acquired over the past several decades, and has integrated that information into a new document, Integrated DNAPL Site Characterization and Tools Selection (ISC-1, 2015). This guidance is a resource to inform regulators, responsible parties, other problem holders, consultants, community stakeholders, and other interested parties of the critical concepts related to characterization approaches and tools for collecting subsurface data at DNAPL sites. After this associated training, participants will be able to use the guidance to develop and support an integrated approach to DNAPL site characterization, including: identify what site conditions must be considered when developing an informative DNAPL conceptual site model (CSM); define an objectives-based DNAPL characterization strategy; understand what tools and resources are available to improve the identification, collection, and evaluation of appropriate site characterization data; and navigate the DNAPL characterization tools table and select appropriate technologies to fill site-specific data gaps.

Climate Adaptation Profiles: Port Hadlock - Site 10 North End Landfill. Executive Order 14008, Tackling the Climate Crisis at Home and Abroad, requires federal agencies to develop climate action plans that describe their agency's climate vulnerabilities and their agency's steps to bolster adaptation to the impacts of climate change. EPA's 2021 Climate Adaptation Action Plan accordingly outlines actions being taken to integrate climate adaptation into EPA policies and programs, including those addressing contaminated sites. One action involves developing site-specific profiles that illustrate a range of processes and tools for evaluating site vulnerabilities to future climate scenarios and adapting to the projected scenarios, thereby assuring site cleanup remedies remain protective of human health and the environment. The first profile release in this series describes adaptation measures taken at the Port Hadlock - Site 10 North End Landfill, a Superfund site on Naval Magazine Indian Island, Washington. The remedy includes a capped landfill, a vegetated geogrid and a shoreline protection system that are vulnerable to potential erosion due to tidal action and storm surge from the bordering Olympic Peninsula inlet. Long-term maintenance of the vegetated geogrid and shoreline protection system was deemed preferable to more aggressive climate resilience measures that could negatively affect local shellfish harvests, including those of Native American tribes holding harvest treaty rights.

In line with the renewed Agency emphasis on sustainability and climate change resilience and mitigation, the Superfund Program is proceeding to update the very popular green remediation (GR) best management practice (BMP) fact sheets for the most common remedies in the Superfund program. The goal of these fact sheets is to share technical information on best practices that build sustainability into contaminated site cleanup operations across the portfolio of remediation approaches. The updated GR fact sheet on integrating renewable energy describes and illustrates use of BMPs involving applications of a site's natural solar, wind or geothermal resources at a wide range of scales. It also addresses the need to assess and optimize energy usage of an existing or anticipated remediation system in advance of renewable energy planning and describes approaches to purchasing green power generated by other parties. The updated GR fact sheet on soil vapor extraction (SVE) and other air-driven systems outlines BMPs that can help minimize the environmental footprint of constructing, operating, maintaining and monitoring cleanup remedies involving SVE, air sparging or vapor intrusion mitigation technologies. Both fact sheet updates highlight synergies between green remediation and climate adaptation practices, where one action provides both greenhouse gas mitigation and climate resilience.

NIEHS Superfund Research Program (SRP) grantees developed a new computational approach to predict how hazardous substances may affect health based on key changes in cells. Led by April Z. Gu, Ph.D., of the Northeastern University Puerto Rico Testsite for Exploring Contamination Threats (PROTECT) SRP Center, researchers used machine learning and advanced algorithms to link biological changes from high throughput cell studies with health outcomes observed in animal studies.

Cyanobacteria is a bacterial phylum (Stanier 1977[5236]), and cyanobacterial species are a common component of the microbial communities found in water or growing at the bottom of oceans, lakes, ponds, rivers, wetlands, and streams across the globe. Cyanobacteria are also found in many terrestrial environments. The scope of this document is freshwater non-planktonic HCBs that are primarily attached or loosely associated with various surfaces and includes the movement and fate of these mats once they detach and disperse. This document is a companion to the ITRC's HCB-1 guidance document (ITRC 2021[5119]). For more information and to view the document, please visit https://hcb-2.itrcweb.org/.
