EPA compliance record

What EPA's record shows

No health-based violations in the last 10 years, from EPA's SDWIS compliance database.

  • Lead: the 90th-percentile result in the latest lead and copper round (the round ending December 31, 2024) was not detected. The federal action level is 15 µg/L, a trigger for more treatment steps, not a legal limit.
  • Missed or late tests or reports: 5 in 10 years.
  • EPA lists 3 enforcement actions in 10 years; the latest on February 19, 2026.

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.

    Safe Home (EnviroTestKits)

    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.
