1980s–present

Based on where it sits
- •Lead service lines — an estimated 20,000+ remaining lead connections. Private-side replacement runs $3,000–$8,000
- •Combined sewer overflows (CSO) during heavy rain, especially in Manayunk, East Falls, and South Philadelphia
- •Flood zones along the Schuylkill and Delaware rivers — Eastwick, Manayunk, and Cobbs Creek are repeatedly flood-impacted
- •PA DEP contamination — brownfields and UST sites within 1 km of many parcels, plus PFAS near Willow Grove Naval Air Station
