  • Missed or late tests or reports: 1 in 10 years.
  • EPA lists 1 enforcement action in 10 years; the latest on March 9, 2022.

    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.
