What is a Health Assessment?

A health assessment is an evaluation of a chemical release and how exposure to that release might affect people’s health.  A health assessment is an evaluation of information related to a hazardous chemical being released into the environment, usually at a hazardous waste site.  The evaluation determines whether exposure to that chemical might cause harmful health effects.  The Health Advisor, who prepares the assessment, looks at past, present, and future exposures.  Once the evaluation is completed, the assessment will have specific recommendations on how to protect public health.  There are three sources of information used to evaluate a site:

  • Environmental data.

  • Information on exposure effects (toxicology) and community-wide rates of disease compared with national and state rates.
  • Information from community members about how the site affects their health or quality of life.

Information Needed to Conduct a Health Assessment

The Health Advisor needs very specific information to conduct the health assessment in order to determine whether the public has been impacted by hazardous chemicals being released from a site.  The following information is used to make that determination: 

  • Site location.

  • Who has used the site and for what purpose.
  • What concentrations of chemicals were found in air, soil, and water.
  • How might exposures to those hazardous chemicals occur.
  • Would there be any health effects from those exposures.

Who Conducts Health Assessments?

The Washington State Department of Health has a cooperative agreement with the Agency for Toxic Substances and Disease Registry, a federal public health agency, to conduct assessments of hazardous waste sites in Washington State. The Department of Health has formed a team, made up of four Health Advisors; a Toxicologist; an Epidemiologist; and a Community Educator, to determine possible public heath problems caused by chemicals released into the environment at hazardous waste sites around the state.

Types of Health Assessment Reports

The following list of reports are prepared by our assessment team.  The type of report prepared will depend on whether an exposure has occurred.
  • Public Health Assessment (PDF Fact sheet) is an evaluation of a hazardous waste site.

  • Health Consultation (PDF Fact Sheet) is a response to a specific question on a chemical(s) found at a site.
  • Exposure Investigation is additional sampling done by an assisting agency.  The results are evaluated to determine health effects due to exposure to known chemicals from a site.

How to Get Involved in a Health Assessment

Our goal is to keep community members, appropriate agencies, and health professionals informed of our assessment recommendations and site activities.  We do that through community education and involvement such as: public information meetings, medical conferences, press releases, fact sheets, and reports.  Two-way communication between affected community members and our assessment team is necessary for a successful evaluation, and helps us improve our services.  We welcome the involvement of Washington residents and encourage questions and comments about sites.  To contact us, call toll free at 1-877-485-7316 or contact the
local health jurisdiction in your county.

Input from affected community members helps identify:

  • What health affects or concerns they are experiencing.

  • What they think about our activities and recommendations.
  • Ways we can communicate better.
  • Ways we can effectively address their needs.

What to Expect from a Health Assessment

The assessment conclusions identify whether there is a public health hazard associated with site-related chemical exposures.  Based on our conclusions, we make recommendations that advise federal, state, and local agencies on actions to prevent or reduce people's exposure to any hazardous chemicals released at those sites.  Protective measure are also presented in the assessment for affected community members to take action to protect their own health.  The following are examples of assessment recommendations:

Residential drinking water is found to be contaminated at levels of health concern:

    We would recommend that impacted residents get their drinking water from another source.

Chemicals are found in the soil at levels of health concern:

    We might recommend that the site be fenced, also that steps be taken to ensure that contaminated soil doesn’t migrate from the site.

The Department of Health follows-up on recommendations that require actions by agencies such as the Washington State Department of Ecology and the U.S. Environmental Protection Agency, to ensure that public health is protected from harmful chemicals released into the environment from a hazardous waste site.

The Site Assessment Section team can conduct health assessments at any hazardous waste site or suspected site, so long as there is data to evaluate. An assessment can be requested by federal, state, or local entities as well as local health jurisdictions or concerned citizens. To find out more information about requesting a health assessment, please contact the Site Assessment Section or call toll free at 1-877-485-7316.
