We will select 2,000 individuals (1,400 from the impacted community and 600 in comparison areas) 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 2,000 survey participants, we plan to select 600 individuals (400 from the impacted community and 200 in comparison areas) for the Study’s clinical assessments and medical testing with the goal of achieving a representative sample.
