Central ASG (EPA ID AS9711948) in Pago Pago, AS supplies surface water (rivers, lakes) to about 45,315 people: 16 violations since 2016, latest lead result 1200 ppb, PFAS 1 detected.
Health-based violations since 2016: Revised Total Coliform Rule, Groundwater Rule, Surface Water Treatment Rule. 1 is still listed as unresolved in EPA records.
The 90th-percentile lead level in the latest round (Jan 2017) was above EPA's 15 ppb action level, which requires the utility to take further steps.
PFAS were detected, with PFOA and PFOS below 4.0 ppt (highest not detected).

EPA Fifth Unregulated Contaminant Monitoring Rule (UCMR 5), samples 2023–2025; ppt = parts per trillion (ng/L). The 4.0 ppt maximum contaminant levels for PFOA and PFOS were set by EPA in 2024; water systems have until the end of the decade to comply.
What this is — and isn’t. These are records your water utility and state reported to the EPA, and the EPA’s radon map for your county. They describe the system and the area, not the water from your own tap or the air in your home. For that, read your utility’s annual Consumer Confidence Report and test: lead and radon tests are inexpensive.
