Impact analysis
State funding includes $5 million in ARPA allocations and grant funding for small and disadvantaged communities, while utility-scale treatment upgrades would require significant capital investment.
All Flagstaff residents and water consumers benefit from transparent monitoring, proactive water quality testing, and public health safeguards.
Residents relying on private wells or vulnerable populations sensitive to low-level contaminants may face risks if advanced treatment is not implemented.
