Mission:
Wisconsin has a long tradition of strong local health departments committed to protecting people in their communities. Every day local health departments address a wide range of environmental health concerns, such as drinking water contamination, lead poisoning, and Lyme disease. The Wisconsin Tracking Program assists local health departments in tackling these issues by:
- Hosting a cutting-edge environmental public health data portal
- Developing and disseminating County Environmental Health Profiles
- Creating fact sheets, toolkits, videos, and other resources
- Offering technical assistance in epidemiology, communications, and evaluation
Quick Stats:
- In Wisconsin, four in ten householdspdf iconexternal icon rely on private wells for their drinking water.
- Carbon monoxide poisoning became a reportable acute condition in 2018 and an improved surveillance system is now in place.
- One in four Wisconsin homes were built before 1950, a key risk factor for childhood lead poisoning.
- Wisconsin is among the 14 states that account for 95% of all Lyme disease cases.
Wisconsin Tracking supports more nationally-accredited health departmentsexternal icon than any other Tracking grantee.
