Lead-Safe Wisconsin: Resources for Lead Investigators

If you're a certified lead risk assessor, hazard investigator, inspector, or sampling technician, the Department of Health Services (DHS) can help improve your lead investigation work and reports. We can give you feedback and suggestions to improve clarity and make sure your work complies with Wis. Admin. Code ch. DHS 163.

We routinely review lead investigation reports from certified investigators across the state. If we review your report, we'll contact you to schedule an informal meeting to share feedback and answer any questions you may have.

Other ways we can help:

  • By reviewing your draft report before you finalize it for the client.
  • By joining you during your investigation to provide real-time feedback.
  • By answering questions sent by phone, email, or during an online Q&A session.

Please email Sara Krueger at or call 608-261-6855 for assistance.

Online Q&A sessions

We now hold quarterly Q&A sessions about lead investigations. We'll answer your questions and share tips about this work.

All certified lead investigators will receive an email inviting them to join the session. To make sure you receive the invitation, please verify that your email address on file is current.

Our next Q&A session is on May 9, 2024.
