Topsfield water FAQ
How is Topsfield's water quality scored?
PurityRadar computes a 0–100 score from public EPA records for the community water systems serving Topsfield. The city-wide figure shown is the average of those systems.
Where does the data come from?
EPA SDWIS — the federal Safe Drinking Water Information System — covering active community water systems and their health-based violations. Every figure traces back to that public record.
Is this a substitute for testing my tap?
No. System-level data can't account for your home's own plumbing (lead service lines, fixtures). For health decisions, test your tap with a certified lab and confirm with your utility.
