What We Do & Why It Matters
The Environmental Health Division of the Livingston County Health Department is dedicated to protecting public health by ensuring safe food, clean water, proper waste disposal, and effective control of disease-carrying pests.
We work to make sure:
The food you eat is fresh, healthy, and safe.
Your well water is clean and free from harmful contaminants.
Septic and geothermal systems are properly maintained and functioning safely.
Vector-borne diseases (like those carried by mosquitoes and ticks) are monitored and reduced through prevention efforts.
These services are essential for creating a healthy, safe environment where our residents can live, work, and thrive.
Education. Guidance. Inspections. Surveillance.
Our Environmental Health team plays a vital role in protecting the health of Livingston County residents through education, inspections, and disease prevention efforts.
Environmental health sanitarians conduct inspections and provide expert guidance in key areas such as:
Food safety
Private sewage systems
Private water supplies
These efforts help prevent the spread of disease and ensure the safety of our community’s everyday essentials.
In partnership with the Illinois Department of Public Health, we also provide surveillance and response for vector-borne diseases. This includes:
Monitoring and testing for West Nile virus
Identification of disease-carrying vectors such as ticks, mosquitoes, fleas, and rodents
Complaint investigations related to public health risks
Proper identification and education are critical. We work to inform the public on safe, effective methods of prevention, control, and elimination of these health threats—reducing the risk of vector-borne illnesses across our communities.
