Plumbing inside a home can add lead that the system record can't show. A tap test tells you what reaches your glass.
lead 1.86 µg/L, below the 15 µg/L action level
PFBA 7.4 ng/L detected (no federal or state limit)
Screening tells you if something is worth a closer look; a lab result is the number you can act on.

Screening: quick check, not lab-grade
Safe Home (EnviroTestKits)
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 Lago Vista, PFBA 7.4 ng/L was detected, with no federal or state limit; the lead 90th-percentile result was 1.86 µg/L against the 15 µg/L action level. CITY OF LAGO VISTA (PWSID TX2270092) has a Purity Score of 92/100 (confidence: moderate), assessed at the water-system level and computed only from contaminants that were measured. Water can change in your own pipes, so a certified test is the only way to know what comes out of your tap.
CITY OF LAGO VISTA (PWS ID TX2270092) is the public water system on record for Lago Vista, Texas, serving about 8,698 people. Confirm the utility on your water bill before acting on a specific finding.
Surface water (primary source of record in EPA SDWIS).
Yes. In EPA's UCMR 5 testing (2024-03-19 to 2025-02-10), PFBA was detected at 7.4 ng/L. It has no federal or state limit, so PurityMap shows it without grading it. No PFAS with a limit was detected.
CITY OF LAGO VISTA's most recent lead 90th-percentile result (2023–2025) was 1.86 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 Lago Vista holds 31 findings: 2 detected within the reference, 1 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.
