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
155 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. 1 events reported to last more than 31 days are counted to 31 days. Official beach and cyanobacteria advisories are counted on water pages only. CT DEEP dashboard records begin 2021-12-02; where CT DEEP's annual report covers a discharger's month, the annual report is counted instead. CT DEEP annual reports (Sewage Right-to-Know) cover 2021-01-01 to 2026-11-02. CT DEEP's reporting archive runs 2016-07-04 to 2021-12-02.

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.
