From EPA SDWIS. A clean violation history means no enforcement action was recorded; it does not cover contaminants without a limit. Meeting a federal limit is a compliance fact, not a health clearance.
Screening tells you if something is worth a closer look; a lab result is the number you can act on.

Lead, read as one of three ranges: 0–4, 5–15 or 15+ ppb
Turnaround: 5 minutes
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.
