Lead-Safe Wisconsin: Laws, Regulations, and Policy Approaches

Both Wisconsin and federal laws protect people from lead. If state and federal rules differ, the stricter one must be followed.

Protecting Wisconsin Children from Lead Poisoning

Lead is a toxic metal. Every year, thousands of Wisconsin children are poisoned because of exposures to lead in paint, dust, soil, old plumbing, and more. Learn more about the impacts of lead poisoning at Lead-Safe Wisconsin: What is Lead Poisoning?

To stop lead poisoning, we must act take action before a child is exposed, catch exposures early, and offer immediate support when a child is lead poisoned.

Lead poisoning is preventable. By aligning strong policy, dedicated funding, and targeted public health strategies, we can end lead poisoning in Wisconsin.

What Wisconsin's lead laws cover

Wisconsin has several statutes and rules about lead hazards. They set requirements for:

  • House sales.
  • Landlord and tenant agreements.
  • Lead hazard reduction and renovation.
  • Public health response to lead poisoned children.
  • Residential facilities.
  • Reporting blood lead test results for adults and children.

Opportunities for system changes

Wisconsin local health departments are being asked to do more with less, strained by outdated laws and lack of state investment.

The Centers for Disease Control (CDC) recommends that all children with lead poisoning receive a public health response. A child is considered lead poisoned if they have a blood lead level over 3.5 micrograms per deciliter. Wisconsin law, however, does not require a response until a child's blood lead level is 4 times higher. This leaves thousands of children unsupported.

The following strategies, when implemented together, will mean fewer lead poisoned children in Wisconsin.

Waiting to respond until a childhood lead poisoning case becomes more severe is dangerous and worsens the health outcomes.

Aligning statutory requirements for a public health response to the state definition of lead poisoning would help to stop childhood lead exposures sooner. A University of Wisconsin-Madison cost-benefit analysis found that this would result in an estimated $2.5 billion in net benefits.

Local health departments urgently need resources. State funding for local lead poisoning response was established over 30 years ago, in 1993, and has not been increased since.

Increasing state resources would allow local health departments to provide comprehensive lead investigations, nursing case management, and education to the families of all lead poisoned children.

The only way to prevent lead poisoning is to stop exposure to lead.

Wisconsin families need support for removing dangerous lead paint hazards from their homes. Establishing programs to help low- to moderate-income homeowners replace lead-painted windows, doors, and other high-risk building components would give families they power they need to stop lead poisoning before it happens.

When local governments have the authority to address unsafe rental housing, they can confront lead hazards before children are poisoned.

Supporting local governments' ability to establish sustainable programs based on local housing and public health needs would help to decrease the prevalence of childhood lead poisoning.


Current Wisconsin laws and regulations

Other state agencies enforce additional rules, such as rules for drinking water and child care licensing. To learn more, visit:


Current federal laws and regulations

  • OSHA lead standards: These standards protect people who paint, renovate, or use paint in other ways.

  • Safe Drinking Water Act (SDWA): Protects people from lead in drinking water by required EPA to set national rules for public water systems to reduce exposure to lead in drinking water and by prohibiting the use of sale of plumbing materials that contain lead.
    • Lead and Copper Rule: Established requirements for monitoring, corrosion control treatment, public education, and lead service line replacement to reduce lead and copper levels in drinking water.
    • Lead Free Rule: Implements statutory restrictions on the use, sale, and distribution of pipes, plumbing fixtures, solder, or flux that are not "lead free."
  • Clean Water Act (CWA): Prohibits discharges of pollutants, including lead, form a point source to a water of the United States unless authorized.
  • Resource Conservation & Recovery Act (RCRA) & Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA): RCRA regulates hazardous lead-bearing waste with leachable concentration of lead at 5ppm or greater from the point of generation to ultimate disposal in a controlled environment, helping to prevent lead from being released into the environment. CERLA addresses lead after it has been released into the environment.
  • Clean Air Act: Gives EPA authority to regulate lead in multiple ways, including by setting national ambient air quality standards and emission standards for lead and regulating the use of lead as a fuel additive.
