Water quality score
60/ 100Limited data

Only 1 of 27 core regulated contaminants were reported for Forest Park Water Users Association, MT. What was measured is not clean — but most of the picture is missing.

  • !1 contaminant at or above a federal limit — worst is Lead at 1.0x
  • !1 of 27 core regulated contaminants reported — 26 never appear in this report
  • No open federal violations
+How this score is calculated

Every system starts at 100. Points come off for measured levels, for the federal violation record, and for how much of the core regulated set the utility actually reported. All three inputs are the utility's own published numbers and EPA's own records.

  • 12  contaminants at or above a federal limit
  • 0  contaminants within 20% of a limit
  • 0  open health-based violations
  • 0  open monitoring / reporting violations
  • 0  health-based violations resolved in the last 5 years
  • 28  core regulated contaminants never reported (1/27)

A 90–100 · B 80–89 · C 70–79 · D 60–69 · F below 60. A system reporting under a third of the core set is capped at C however clean its numbers look — a short report is not a clean bill of health.

What to worry about

  • Lead1.0× the federal limit
    0.015 mg/L · limit 0.015 mg/L

    There is no safe level of lead; it harms brain development in children and raises blood pressure in adults. The EPA sets an action level, not a health goal above zero.
