Risk Communication of Waterborne Contaminants Case Studies

In early 2018, the Association of State and Territorial Health Officials (ASTHO) and the Environmental Council of the States (ECOS) interviewed health and environmental agency staff from 13 states regarding their risk communication strategies and lessons learned for two priority waterborne contaminants, per- and polyfluoroalkyl substances (PFAS) (6 states) and harmful algal blooms (HABs) (7 states). They compiled the results into case studies that outline the background of contamination in the state, development of guidance values and health advisories, rollout of advisories and relevant resources, key messages for the public, and challenges and gaps.
