All three cited PRIMARY sources (baldwin.senate.gov) are reachable, support the promise topic, and contain the quoted language verbatim. The CHAMPIONED (leadership) bar is met: Source 2 documents Baldwin as lead co-sponsor/author (with Sen. Collins) of the bipartisan Healthy H2O Act (introduced 3/15/2023), which creates USDA grants for water testing and PFAS/lead/nitrate treatment for rural households — genuine legislative authorship, not a mere vote. Source 3 shows her securing $1.6M in appropriations for Eau Claire PFAS remediation (she "secured the funding" as part of the 2023 funding bill — earmark-level leadership, again beyond a vote). Source 1 documents delivery of $119.6M in Wisconsin clean-drinking-water funding covering both lead-pipe replacement and PFAS. Together these satisfy both halves of the promise (clean water for Wisconsin communities + addressing PFAS) with demonstrated leadership. Confidence held at 0.82 because the Healthy H2O Act itself was not yet fully enacted as of mid-2026 (pending Farm Bill), though the appropriations funding was enacted and delivered; Source 1 by itself reads as funding-announcement rather than authorship, so the leadership finding rests primarily on Sources 2 and 3.
