Status now

Caution

The authority's window has passed but the discharge ended less than 72 hours ago, or a discharge with no reported end began in the last 7 days, or a rainfall advisory is posted. Research on sewage-borne illness points to about three days of raised risk.

Why this colour: Caution: no end reported. Rationale: A discharge record with status unknown (an alert with no incident report, an unparsed notice) is yellow for 14 days from its report time, then unresolved as above. (source: data/rules.json) How long a water stays coloured, and why

What the authorities advise

“Avoid contact with these water bodies for 48 hours after the discharge or overflow ceases due to increased health risks from bacteria and other pollutants. See website for more information on whether specific resource areas, such as bathing beaches, are affected.”

Map

Source: water outlines from OpenBoatLaunch and OpenStreetMap contributors (ODbL); outfalls from EPA ECHO and the state outfall layers; modeled reaches computed by DirtyWaterWatch from USGS NLDI, NHDPlus and the nearest USGS gauge (Jobson 1996); basemap OpenFreeMap and OpenMapTiles.

Outfalls are small brown dots; modeled downstream reaches are dashed.

Modeled downstream reaches on Connecticut River

Modeled downstream reach (estimate, not verified by sampling). Computed by DirtyWaterWatch from the river network and the nearest flow gauge; it is not an official advisory area.

Traced outfall paths

Source: paths traced by DirtyWaterWatch on the USGS NLDI / NHDPlus network from each outfall to the head of tide, the first lake or the distance cap; statuses from the events on them.

The last 90 days

Last 90 days, hour by hour. Red: advisory in effect; yellow: caution; hatched yellow: unresolved, no end reported; grey: no current report; hatched purple: a source was not updating.

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.

  • EPA ECHO sewer overflow events: 2022-05-03 to now (sparse)
