Human health risk assessment, U.S. EPA guidance, cancer risk, noncancer hazard index, exposure assessment, toxicity assessment, risk characterization, regional screening levels (RSLs), regional removal management levels (RMLs), vapor intrusion screening levels (VISL), radionuclide preliminary remediation goals for radionuclides (PRGSs), radionuclide dose compliance calculators (DCCs), radon vapor intrusion screening levels (RVISL), the risk assessment information system (RAIS), and more.
Registration is now closed.
The organizers of this training have been publishing online "risk" (cancer risk and noncancer hazard index) calculators since 1996; this training will primarily provide the participant with operational knowledge of key EPA and RAIS calculators. Additionally, the training and exercises will delve into the ability of the calculators to address site-specific exposures, unique toxicity assessments, and complex risk characterizations. Comprehensive instruction will demonstrate the calculator's ability to provide all the tables necessary for exposure, toxicity, characterization, and uncertainty assessment sections of a risk assessment. Instruction into the details of the equations will enlighten users on how the calculators handle the following special cases: mutagens, vinyl chloride, trichloroethylene, arsenic, dioxin-like PCBs, PAHs, skin absorption factors, volatile chemicals in soil, volatile chemicals in tap water, petroleum hydrocarbons, surrogate toxicity values, soil saturation, and soil screening levels protective of contaminant migration to groundwater. Participants will learn to adjust standard chronic land uses to subchronic exposures. Participants will learn to retrieve and analyze the physicochemical properties and evaluate the hierarchy used to assemble the database. Participants will learn to retrieve and analyze the toxicity value hierarchy used in the screening level and risk calculators. In addition to a large focus on developing risk-based screening levels, participants will derive "forward" risk results from the EPA screening calculators and use the RAIS calculators to generate chronic daily intakes and risk results. At the end of each section or day, several practice sessions will reinforce the use of calculator functions. Practice sessions will become more challenging as the course progresses, helping participants solidify their risk assessment skills.
This training is intended for fresh and seasoned environmental professionals working on risk assessment projects at the Federal or State level. The risk calculators covered in this training are used by many State government agencies, Federal agencies, university staff, and researchers. Participants who are educators and project managers will also benefit from the training. A very basic knowledge of risk assessment, computer usage, web browsing, and good manners is assumed.
Continuing Education Credits:
Chemical risk tools = 1.7 credits (Days 1-3); Radionuclide risk tools = 0.7 credits (Day 4)
Bring your laptop! This is a hands-on course, and participants will be following the instructors click for click. Don't forget your charger. Instructors will be presenting all calculators using Chrome, so make sure Chrome is available on your laptop. Not required, but useful would be spreadsheet software and a PDF viewer. Wi-Fi will be provided.
*Minimum number of participants has been met.
**All fees include light snacks and beverage service throughout the day. Lunch will be at the ORNL cafeteria and payment responsible by the attendee.
Attendees are responsible for their own lodging and transportation to and from the training.
