Reported volume per year

Gallons, summed from the 979 events that gave a number (939 did not).

  • Partly covered or sparse source

939 of 1,918 events gave no volume as a number (609 gave a range); only numbers are summed. Some CT DEEP annual-report volumes are given as text or ranges and are not summed. CT DEEP's 2016-2021 archive gives volumes as ranges ("20,001 - 50,000 gallons"); they are not summed.

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.
