ITRC Environmental Data Management (EDM): Best Practices for Exchanging Environmental Data - April 6, 2023, 1:00PM-2:30PM EDT (17:00-18:30 GMT). The
ITRC Environmental Data Management Best Practices Team (EDMBP Team) prepared a series of guidance documents and case studies on best practices for all phases
of EDM to address the need for guidance on managing large stores of environmental data. Environmental data management (EDM) is a broad field that encompasses
all aspects of environmental research and regulation, from habitat studies and wildlife management plans to health advisories and remediation of hazardous
waste sites. The EDMBP Team developed three Roundtable training sessions to support the Guidance Document and case studies. An additional offering is scheduled
for May of 2023. You are welcome to register for any of the series, but they do not build upon each other. For more information and to register, see https://www.itrcweb.org
or https://www.clu-in.org/live.
SERDP ESTCP In Situ and Ex Situ Approaches for Treating PFAS-Impacted Groundwater - April 6, 2023, 12:00PM EDT (16:00 GMT). This webinar will feature DoD-funded
research efforts to treat PFAS-impacted groundwater in situ and ex situ. First, Dr. Charles Werth (University of Texas at Austin) will present his work on the

ITRC PFAS Introductory Training - April 13, 2023, 1:00PM -3:00PM (17:00-19:00 GMT). Per- and polyfluoroalkyl substances (PFAS) are a large and complex
class of anthropogenic compounds whose prevalence in the environment are an emerging, worldwide priority in environmental and human health. The ITRC PFAS
Team, formed in 2017, has prepared readily accessible materials to present PFAS information to stakeholders, regulators, and policy makers. The PFAS team
represents a diverse cross-section of expertise and experience working on PFAS.This training will include emerging science on PFAS, including topics such
as Properties of PFAS, Fate and Transport, Sampling and Analysis, and Treatment Technologies. The technical presentations will be focused on those who are
relatively new to PFAS. The training will last approximately 90 minutes and include time for questions. For more information and to register, see https://www.itrcweb.org

Using Quickscore 3.2.2 for Superfund Site Assessments - April 18, 2023, 1:00PM-3:00PM EDT (17:00-19:00 GMT). HRS Quickscore is a standalone application
that assists users in scoring sites applying the Hazard Ranking System (HRS). In this course users will be introduced to Quickscore 3.2.2. The course will feature
a live demonstration of Quickscore that will show users how to enter site level documentation, source data, and pathway information for each of the four HRS
pathways: ground water, surface water, soil exposure and subsurface intrusion, and air. Attendees will learn how to enter information and score a hypothetical
site in Quickscore 3.2.2. If you have specific questions or suggestions related to Quickscore, please email the Quickscore Helpline (Quickscore@gdit.com)
ahead of the training session and the instructors will address these during the training, as time allows. Attendees are encouraged to download and install
Quickscore 3.2.2 (https://www.epa.gov/superfund/superfund ... prior to the webinar.
SRP Progress in Research Webinar: Session I Emergencies and Emerging Contaminants - April 28, 2023, 12:00PM-2:00PM EDT (16:00-18:00 GMT). This Progress
in Research webinar series will showcase research from 11 new and renewed Multiproject Center grantees, funded by SRP in 2022. These awards were made as part
of the P42 grant solicitation RFA-ES-20-014. In the four-part series, awardees will highlight their research projects, accomplishments, and next steps.
Additional sessions are offered on May 5, 12, and 19. For more information and to register for the series, please visit https://www.clu-in.org/live.

Green Remediation Best Management Practices: Cleaner Fuels and Air Emissions for Site Cleanups (EPA 542-F-23-001). Environmental investigation and
remediation at hazardous waste sites can involve significant consumption of fossil fuels by vehicles and mobile or stationary equipment powered by internal
combustion engines. Burning of gasoline, diesel and other fossil fuels results in emission of air pollutants such as particulate matter and carbon dioxide,
a greenhouse gas that greatly contributes to climate changes. It also increases production of ground-level ozone that can trigger human health problems and
may exacerbate environmental justice concerns in certain communities. The updated EPA fact sheet on this topic describes and illustrates best management
practices (BMPs) intended to minimize fuel consumption and air emissions due to operating equipment such as power generators and onroad or offroad vehicles
such as light- or heavy-duty trucks, tractor trailers and excavators. Key strategies focus on deploying engines and vehicles equipped with advanced emission
control technologies, conserving the fuel required to operate engines and vehicles, and integrating BMPs in project-level transportation plans for activities
such as offsite disposal of waste. Such strategies are critical as the U.S. continues to transition to an electric economy. To view or download, please visit https://www.clu-in.org/greenremediation/ ...
Superfund Research Brief Number 339: New Model Estimates PFAS Exposures From Contaminated Drinking Water. Researchers partially funded by the NIEHS Superfund
Research Program (SRP) developed a model to estimate individual exposure to four per- and polyfluoroalkyl substances (PFAS) commonly found in drinking water.
The model integrates published data from multiple studies on PFAS levels in human blood along with measured PFAS concentrations in drinking water. Tools for
estimating PFAS exposure from contaminated drinking water can inform public health risk assessments and advisories. The analysis is the largest to date of
its kind, according to the team, which included researchers from the Texas A&M University (TAMU) SRP Center, Abt Associates, and the Agency for Toxic Substances
and Disease Registry (ATSDR), part of the Centers for Disease Control and Prevention. For more information and to read the brief, please visit https://tools.niehs.nih.gov/srp/research ...
New Focus Area: Chlorinated Solvents. Chlorinated solvents have been used for a variety of commercial and industrial purposes, such as degreasers, drycleaning
solutions, paint thinners, herbicides, pesticides, resins, glues, and a host of other mixing and thinning solutions. Visit the Chlorinated Solvents Focus
Area at https://www.clu-in.org/Chlorinated-Solve ...
New Focus Area: Polycyclic Aromatic Hydrocarbons (PAHs). PAHs are formed by the incomplete combustion of coal, oil, gasoline, garbage, residential wood
