Understanding the PHA Process

ATSDR performs the public health assessment (PHA) process to determine whether people living near a hazardous waste site are being exposed to toxic substances, whether that exposure is harmful, and what must be done to stop or reduce exposure. The process enables ATSDR to identify and prioritize follow-up activities to protect public health.
