Should local city governments be responsible for testing water safety in unincorporated neighboring areas?
The Arizona Department of Environmental Quality has directed larger cities to expand their PFAS exposure studies to include adjacent unincorporated areas. This mandate aims to ensure comprehensive data collection in regions where multiple entities manage local water supplies.
Why it matters
Expanding these studies to unincorporated communities like Granite Dells and Forbing Park is critical because multiple companies and governments operate water infrastructure in the area. Integrating these locations provides a clearer picture of potential environmental exposure across the region.
The regulatory request covers studies across the Quad Cities region to account for diverse water management. It remains unknown how many additional residents will be included in the expanded scope of these environmental assessments.

Residents in areas like Granite Dells and Forbing Park may see more consistent water quality data provided by their local municipalities. This change could lead to increased transparency regarding local utility operations for homeowners and business operators in unincorporated zones.
The takeaway
Expanding environmental testing to include all jurisdictions ensures that public safety is not compromised by geographic boundaries. Residents should monitor local utility reports for updated water safety data as these municipalities implement the new state requirements.
