Overview of the Environmental Health Bureau (EHB)

What is Environmental Health?

The field of environmental health is not about the birds, bees and trees; it's about you and the places where you live, work and play.

The Environmental Health Bureau (EHB) uses the best available science to reduce, eliminate or prevent harm from environmental, chemical and physical hazards. They also aim to promote environmental justice and equity for the people of Michigan by providing services to those who need them - such as the distribution of water filters to reduce PFAS or lead in drinking water and removal of lead paint hazards from homes. The Bureau also conducts PFAS and other chemical hazard public health investigations; oversees lead abatement, filter distribution and lead poisoning nurse case management; conducts health studies, biomonitoring and epidemiological assessments; puts out advisories for fish and wild game consumption statewide; supports air quality investigations and interventions, including vapor intrusion in homes; and manages the climate and health adaptation program.

Our Goal

We serve to promote and protect the health of the people of Michigan by using the best available methods for epidemiology, toxicology and health education to identify exposures, investigate related health effects and intervene with public health actions. We aim to make sure state residents, especially those who are most at risk, are aware of and can take action to avoid environmental, chemical and physical hazards.

We apply the best available science to end or prevent injury from environmental, chemical and physical hazards, and promote equity for the people of Michigan.

Identify

The first step in our work is to identify potential health threats. These threats are sometimes brought to our attention through data from our partnering State agencies, like the Department of Environment, Great Lakes, and Energy (EGLE) or our federal partners, including the Environmental Protection Agency or the Centers for Disease Control and Prevention. Sometimes, we hear about concerns from people like you. We look at what is known, identify public health hazards and determine next steps through the identification and collection of data.

Investigate

When a health hazard is discovered or suspected, investigation helps us understand who is at-risk from the hazard and determine if any immediate public health actions are necessary. Thorough investigations can occur to provide science-based answers about exposure, injury or the efficacy of intervention. Our staff conduct human exposure assessments, health studies or environmental assessments to determine the public health risks. They work with local, state and federal partners to identify how exposures may be occurring and what can be done to limit those exposures.

Intervene

As populations or individuals are identified as being at-risk from a hazard, MDHHS works to reduce, eliminate or prevent harm – either by providing information about the exposure to those affected or connecting with local, state and federal partners who have the ability to address the hazards. Our staff oversee contracts to conduct lead removal in homes of children who have elevated blood lead levels and distribute water filters in communities to those with need with drinking water that contains lead or PFAS, among other direct interventions. We also work to better inform the public by sharing data, issuing public health advisories and developing and distributing educational materials to help you understand risks and actions you can take to keep you and your loved ones safe and healthy.

 

Bureau Divisions

Division of Toxicology and Response

Mandy Paust, Division Director - 517-896-5253

The Division of Toxicology and Response is comprised of 3 sections:

  • Toxicology and Assessment (TAS)
  • Chemical Planning and Response (CPRS)
  • Community Education and Outreach (CEO)

These areas work closely together and with the other two divisions to identify environmental human health hazards, investigate and conduct additional sampling as needed and intervene using best practices in the fields of health education and community engagement.

 

Division of Epidemiology, Data Analytics, and Evaluation

Betsy Wasilevich, Division Director - 517-281-5516

The Division of Epidemiology, Data Analytics and Evaluation is comprised of 3 sections:

  • Biomonitoring, Epidemiology and Response (BEaRS)
  • Environmental Epidemiology and Analytics (EEA)
  • Environmental Health Surveillance (EHS)

These areas work closely together and with the other two divisions to investigate the human health impacts of environmental contamination. This is done through biomonitoring – including blood tests that assess chemical exposures, identifying disease trends over time and ensuring data transparency through public data visualizations and dashboards.

 

Division of Environmental Community Services

Carin Speidel, Division Director - 517-243-6227

The Division of Environmental Community Services is comprised of 3 sections:

  • Lead Certification and Compliance Section (LCCA)
  • Residential Environmental Services Section (RESS)
  • Care Coordination Section (CCS)

The Division of Environmental Community Services works to protect families—especially children—from the harmful effects of lead and other environmental hazards in their homes and communities through collaboration with clinicians, communities, and local state and federal public health authorities. Division staff provide support and services to individuals and organizations affected by lead exposure and other environmental contamination.

 

The Environmental Health Bureau’s backbone functions are supported by two key offices: the Financial Services Office (FSO) and the Bureau Operations Office (BOO).

Financial Services Office

Hope Bartlett, Office Director - 517-331-2987

The role of the Financial Services Office is to support the Bureau by creating and maintaining allocation budgets, creating and maintaining annual spend plans, conducting compliance testing on contracts to ensure they are audit ready, tracking expenditures, coordinating grant applications, grant reporting, creating and maintaining purchase agreements, grant agreements and spending analysis.

Bureau Operations Office

Michelle Chambers, Office Director - 517-282-4680

Within the Bureau Operations Office, three key areas ensure operational excellence, scientific rigor, and strategic advancement across the bureau. The Operations and Employee Engagement Section fosters internal connectivity and staff support, from daily communications and HR functions to governance and technology tools. The Office of Science & Consultation enriches programs through peer review, technical expertise and mentorship, grounding EHB’s work in scientific best practices. Meanwhile, the Office of Strategy drives innovation and continuous improvement through data modernization, health equity initiatives and rigorous program evaluation. Together, these groups create a dynamic, collaborative infrastructure that empowers staff and elevates the bureau’s impact.
