Guidance
Public Health Assessment Guidance Manual (PHAGM)
PHAGM describes methods and resources that you can use to evaluate environmental exposures associated with environmental contamination. For this competency, please review the following sections 1 through 3 of PHAGM.
- Understanding the PHA Process - ATSDR performs the 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.
- Who's Involved - This section in PHAGM explains ATSDR's role in the PHA process and describes the various groups and individuals involved in the PHA process activities.
- Getting Familiar with the Site - This section in PHAGM describes the steps for gathering pertinent site information during the PHA process. It describes the types of information you will need to collect and available resources for gathering this information.
