  • Missed or late tests or reports: none in 10 years.
  • EPA lists 10 enforcement actions in 10 years; the latest on February 9, 2017.

No lab results for other contaminants (like PFAS) are on file for this system. EPA required that testing from systems serving more than 3,300 people, plus a sample of smaller ones.

    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.
