Illinois systems must send the next lead-line notice in 2026
Cook County TAP
Cook County TAP lists the next Illinois systemwide service-line notice window as May 15 through December 31, 2026.
This card restates a public report.
Federal rule required notice to about 900,000 people by Nov 2024. WBEZ reported ~7% sent by July 2025. The 2025 CCR later recorded a certification failure for 2024 service-line notices.
