Plumbing inside a home can add lead that the system record can't show. A tap test tells you what reaches your glass.
lead 8 µg/L, below the 15 µg/L action level (detected below the limit); 17,772 lead service lines; 4 galvanized lines to replace (context, not a tap measurement)

Lead, read as one of three ranges: 0–4, 5–15 or 15+ ppb
What it can't tell you: It shows a lead range, not an exact level, and tests nothing else unless you pay extra for the optional lab test.
Lab-certified results
ETR Laboratories
50+ substances, including lead, copper, arsenic, nitrate, hardness and coliform bacteria
What it can't tell you: It does not test PFAS, and not every result on the panel falls under the lab's accredited scope.

PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Saint Paul, PFBA 20.2 ng/L and PFPeA 3 ng/L were detected, with no federal or state limit; the lead 90th-percentile result was 8 µg/L against the 15 µg/L action level. Saint Paul Regional Water Services (PWSID MN1620026) has a Purity Score of 90/100 (confidence: moderate), assessed at the water-system level and computed only from contaminants that were measured.

Surface water (primary source of record in EPA SDWIS).
Yes. In EPA's UCMR 5 testing (2023-09-13 to 2024-06-11), PFBA was detected at 20.2 ng/L and PFPeA was detected at 3 ng/L. They have no federal or state limit, so PurityMap shows them without grading them. No PFAS with a limit was detected.
Saint Paul Regional Water Services's most recent lead 90th-percentile result (2025) was 8 µg/L, below the 15 µg/L action level. That figure comes from sampled homes; lead usually enters from a building's own pipes and fixtures, so only a test at your tap tells you what you drink.
PurityMap's current record for Saint Paul holds 31 findings: 1 detected within the reference, 2 detected with no limit and 28 not detected. Each finding links to its dated public record; a parameter that was never monitored is shown as pending, not as a pass.
