We will select 1,400 individuals from the impacted community to participate in the survey. To achieve a representative sample of the affected community, survey participants will be selected utilizing a rigorous address-based approach that takes into account factors such as race, ethnicity, socioeconomic status, and proximity to the wellhead within a 5 to 6-mile radius to the south.

The selected individuals will receive a letter requesting their participation in the survey. From the pool of 1,400 survey participants, we plan to select 600 individuals for the Study’s clinical exams and medical testing. These 600 individuals will also be chosen with the goal of achieving a representative sample of the community.
