Plumbing inside a home can add lead that the system record can't show. A tap test tells you what reaches your glass.

PFBS 3.4 ng/L, below the 2000 ng/L EPA health advisory (+3 more PFAS detected)

Surface water (primary source of record in EPA SDWIS).
In EPA's UCMR 5 testing (2025-02-11 to 2025-11-04), PFBS was detected at 3.4 ng/L, below the 2,000 ng/L EPA health advisory and PFHxA was detected at 6.6 ng/L, below the 400,000 ng/L state limit. PFBA (7.3 ng/L) and PFPeA (7 ng/L) were also detected; they have no federal or state limit.
Lead is not in Cary's current published record. Lead usually enters from a building's own pipes and fixtures, so a certified home test is the way to know yours.
The federal SDWIS record lists a health-based violation for CARY, TOWN OF within about the last ten years: E. coli (2023). The findings above show each one's status.
