Hours under advisory per month
Hours this discharger's reports put a water under an advisory, by the map's red rules.
- Advisory in effect
- No source
- Partly covered or sparse source
No source covers 2022-01 to 2022-05. 13 discharge events have no reported end and no ongoing status; under the status rules they set caution, not an advisory, and add no hours here. Official beach and cyanobacteria advisories are counted on water pages only. MassDEP portal records begin 2022-06-30. Verified Data Reports arrive after the month ends, so the latest months count public notices.

How these charts are counted
Discharge events are counted once: where a source publishes both public notices and verified reports (MassDEP, Vermont DEC), a discharger's month with any verified report counts its verified reports only, and other months count notices. Revisions are folded into the record they revise, and EPA copies of a state report are not counted twice. Monthly and yearly totals (Maine DEP, EPA discharge monitoring reports, Portsmouth) are shown on their own and never added to the event counts. Hours under advisory follow the map's red rules. A muted band marks periods no source covers: a gap there is missing data, not a quiet month.
