Environmental health is a field of study within public health that is concerned with human-environment interactions, and specifically, how the environment influences public well-being. In this module, students explore how environmental pollution impacts public health through comparing cancer rates of areas with known environmental pollutants to the national average through a t-test. This adaptation of the Environmental Pollution and Public Health Project EDDIE module emphasizes water quality (vs air quality) with a focus on PFAS in the instructor slides. It is, however, missing the last element of the usual Project EDDIE A-B-C structure that would guide students through comparison of pollutant concentration between areas with known sources to control sites without such sources, due to the lack of publicly-accessible data on PFAS health impacts. While researchers work to understand PFAS, rebuilding a C module for other regulated drinking water contaminants is highly recommended for future applications of this module.
