The exposure and health impact assessments are essential elements of understanding the impact of the blowout. The Study approach balances evidence obtained from direct resident examinations, focus groups, and surveys; existing health care utilization, birth records, and blood samples; and environmental exposure data.

We will conduct clinical exams to gather evidence of potential exposures during the blowout and current health status of residents. We will use exposure data to determine the likelihood of developing specific health conditions due to the exposure.
