Every violation on an EPA water quality report carries a status. These are EPA's own definitions — they're often misread as more or less urgent than they actually are, so here's exactly what each one means.
Archived
On record, but over 5 years past its deadline — EPA no longer counts this toward the system's current compliance status.
Addressed
Currently open — a formal enforcement action is in progress.
Unaddressed
Currently open — no formal enforcement action on file yet.
Resolved
Fixed — the system returned to compliance.
Why this matters
"Archived" is the one most often misunderstood — it sounds dismissive, but it just means the violation is more than five years past its compliance deadline, so EPA's own policy stops counting it toward the system's current standing. It's still public record, and still shown on every report here, but it's not the same as an active, unresolved problem. "Addressed" and "unaddressed" are both genuinely open right now — the difference is only whether a formal enforcement action has started.
