About the Department of Health (DOH) and the Agency for Toxic Substances and Disease Registry (ATSDR)

The Florida Department of Health (DOH) protects and promotes the health of people living around hazardous waste sites. We review environmental sampling taken from sites where chemicals may have gotten into the air, soil, or water. The federal Agency for Toxic Substances and Disease Registry funds this program to determine the risk for nearby residents. We work closely with county health departments. DOH reviews data from the Florida Department of Environmental Protection and the federal Environmental Protection Agency.

We write public health assessment (PHA) reports. A PHA gives a broad look at an entire hazardous waste site—the soil, water, and air. It looks at all potential health effects from known chemicals at a site. This type of report usually takes about one year to complete. However, if a public health threat is found, we will inform the community immediately. A PHA is not the same thing as a medical exam or a community health study. It looks at the types of chemicals and how much of them were found at a site. It checks this information against the known levels where human health effects could occur. A Public Health Assessment focuses on the present and the future. There is usually not much information or data from the past on the chemicals used or the levels. Occasionally, there is enough data from the past to make an estimate of possible effects from past exposures.

Almost any substance can be harmful at some level. Chemicals range from commonly known poisons like arsenic to less threatening substances such as table salt. We must know the exact substance and the exact amount of it that was present. “The poison is in the dose,” means that a chemical may not be harmful unless it is present in a certain amount. We cannot know if it could have any health effect until we know the actual amount of the chemical that was present. When this information is not available, the possible health effects are difficult to predict.

We consider many aspects of a hazardous waste site. Some of the main questions we ask are the following:

  • What are the levels, or amounts, of harmful substances present?

  • Can people be exposed to, or come in contact with, these substances?

  • Can this substance, in this amount, likely cause harm to people?

  • Are there any other dangers to people such as unsafe buildings or physical hazards?

When making public health decisions about hazardous waste sites, the Florida DOH uses the guidelines that apply to the most sensitive persons in the community. These include the children, the elderly, and pregnant or nursing mothers.

In addition to the environmental data we review, we also consider community concerns, reports, and questions concerning how the site affects people’s health or quality of life. We respond to the community in our report, fact sheets, and in meetings

Once a health assessment report is written we do the following things:

  • Advise the public on how to protect themselves from exposure to chemicals from a site

  • Inform the community of our findings and recommendations

  • Inform community healthcare professionals of our findings and give them helpful materials

  • Advise cleanup agencies on health issues


  • Make or enforce laws or rules concerning hazardous waste

  • Provide medical services for people exposed to hazardous waste

  • Provide cleanup or relocation

  • Take samples, except for some private well testing
