Protecting the Public from Exposure to Hazardous Substances

Tetra Tech converted a classroom training program into an e-learning course about environmental health assessments and health impacts from exposures to chemicals and radiation.

Coordinating with the U.S. Department of Health and Human Services Agency for Toxic Substances and Disease Registry (ATSDR), Tetra Tech converted a classroom training course regarding the Public Health Assessment (PHA) process to e-learning training modules. ATSDR leads public health activities on a federal level to protect the public from site-related exposures to hazardous substances and radiation. The PHA process incorporates the ATSDR’s scientific methodology that is used to evaluate the health impact to the public from exposures to hazardous substances and radiation. The course consists of interactive web-based modules to train staff and partners about the fundamentals of the PHA process, and provides key training on conducting environmental health assessments, researching health impacts from exposures to chemicals and radiation, and providing environmental health education to community members and health professionals.

Tetra Tech’s team of senior health experts developed content related to health effects screening and exposure evaluation, including presenting a case study to effectively convey key concepts. Tetra Tech developed four modules that include exercises, knowledge checks, relevant resources, and a realistic case study. Tetra Tech also conducted course demonstrations with ATSDR’s 508 Compliance Testing Group. Section 508 of the federal Rehabilitation Act addresses requirements to ensure consistency in accessibility by individuals in the federal sector to information and communication technologies (e.g., telephones, cell phones, routers, set-top boxes, computers, software). The course demonstrations identified and incorporated accessibility best practices into the module design. Tetra Tech also prepared documentation to ensure that the modules meet the U.S. Centers for Disease Control and Prevention’s continuing education credit requirements and provide technical assistance for a pilot test of the draft modules by a group of 15 ATSDR stakeholders.
