EH Preparedness Webinars

NEHA aims to improve the capacity of environmental health to address emergency health threats and improve the national preparedness, response, and recovery framework. The NEHA EH Preparedness Webinars page provides up-to-date information on community preparedness topics and resources. 

Fentanyl Contaminated Properties: How Can We Clean Them Up?

Thurs, December 3, 2020, 2:00 - 3:00 PM ET

Fentanyl is a synthetic opioid pain reliever that can be deadly even in small amounts. Emergency responders and hazmat teams risk potential exposure to the opioid when responding to incidents at mixing houses, pill factories, or in makeshift laboratories found in apartments, hotels, houses, garages, and storage facilities. EPA has developed a fentanyl fact sheet to support EPA on-scene coordinators’ providing assistance to local, state, tribal, and county hazmat partners in remediation of opioid contamination.

When developing the factsheet, EPA researchers identified research gaps in the sampling and cleanup approaches of fentanyl contaminated materials. Since the fact sheet was developed, EPA researchers have tested multiple off-the-shelf, easy-to-access products for their ability to decontaminate fentanyl on common materials.

Dr. Lukas Oudejans

Dr. Lukas Oudejans is a Research Physical Scientist with the US EPA Office of Research and Development’s Center for Environmental Solutions and Emergency Response. Over the past twelve years, he has gained vast experience in homeland security programs related to research, development and evaluation of innovative technologies for the decontamination of materials contaminated with chemical or biological agents. Currently, he is leading multiple research efforts to assess and improve on decontamination options for biological and chemical contaminated materials including contamination associated with synthetic opioids such as fentanyl and fentanyl analogs. Dr. Oudejans holds a Ph.D. in Experimental Physics from Radboud University, Nijmegen, The Netherlands.

EPA's Research on Environmental Cleanup and Disinfection of SARS-CoV-2

Tues, June 30, 2020 1:00 PM - 2:00 PM ET

EPA scientists are building on a foundation of world-class research by applying their knowledge to reduce the risk of exposure to SARS-CoV-2, the virus that causes COVID-19. This research will help states & territories, tribes, and local governments, including public health agencies guide homeowners, business owners, and others reduce the risk of exposure. This webinar will highlight research EPA is working on related to environmental cleanup and disinfection.

Reducing the risk of exposure to SARS-CoV-2 relies on effective cleaning and disinfection. Presenter and EPA scientist Dr. Shawn Ryan will discuss how EPA researchers are assessing the use of disinfectants on many different surfaces and objects as well as determining the best environmental sample collection methods and the limits of detection for SARS-CoV-2. To determine the effectiveness of these approaches, researchers are also developing a method to quickly analyze surface samples for the live virus, both before and after the disinfection process. Dr. Ryan will also discuss the development of strategies to decontaminate PPE.

EPA's CyAN Mobile App Provides Early Detection of Algal Blooms in U.S. Freshwater Systems

Wed, Nov 13, 2019 1:00 PM - 2:00 PM EDT

The CyAN App is a mobile application that uses satellite data to map the location of harmful algal blooms in waters across the US. The app provides weekly information about cyanobacteria concentrations in many of the largest water bodies in the country. This information can be used to inform decisions regarding recreational and drinking water safety. The CyAN App is designed for use on Android™ devices and is available for download on Google Play™. This webinar will provide a general overview of the app including what it is used for, why and how it was developed, and who it was designed for, as well as state case studies from their beta testing of the CyAN app.

Speakers include:

Blake A. Schaeffer, Ph.D.
Blake is a physical scientist with EPA's Office of Research and Development in Durham, North Carolina. His research focus is on the use of satellite remote sensing technology to monitor water quality in coasts, estuaries, and lakes. Blake's interests generally include integrating remote sensing technologies into water quality management frameworks.

John M. Johnston, Ph.D.
John is a supervisory research ecologist with EPA's Office of Research and Development in Athens, Georgia. His research focus is on water quality monitoring and modeling to forecast ecosystem services and their influence on human health. John's interests include life cycle impact assessment, remote sensing, spatial modeling, and sustainability analysis.
