Hello, I am ______________________ from [insert affiliation], calling on behalf of the Agency for Toxic Substances and Disease Registry. May I please speak to someone who can make decisions about participating in our study?

As I’m sure you remember, your household recently agreed to participate in an exposure assessment to measure chemicals called per- and polyfluoroalkyl substances, or PFAS, in the bodies of people living in your area. A small subset of households participating in the exposure assessment has been selected for additional environmental sampling of PFAS in the home.

We would like to collect tap water and indoor dust samples from some homes to understand if people living in your area are exposed to PFAS while at home. To do this, we need households in this community to participate in environmental sampling as well as blood and urine testing.

For this part of the exposure assessment, we will collect a drinking water sample from the source in your home you and your family most often drink water (e.g. kitchen tap). Then, we will collect indoor dust samples from up to three locations inside your home. The time required for us to collect these samples is estimated to be about 20 minutes. The environmental sampling will be in addition to collection of blood and urine from you and others in your household.

Are you willing to participate in the environmental sampling part of the exposure assessment?
