Wastewater outlets

Outfall: a pipe or outlet where wastewater enters a water body.

1 treatment plant outfall listed by EPA or state agencies; 5 places named in its own overflow reports (provisional locations).

Treatment plant outfalls

1 outfall

Source: U.S. Environmental Protection Agency (EPA) permit records (ICIS-NPDES permitted features): where a treatment plant’s permitted discharge leaves. No national source says whether a plant outfall is open or closed.

Places named in overflow reports (provisional)

5 places · 1 not on the map (reports say the sewage reached no water)

Provisional location from overflow reports. Where the operator's own reports put an overflow: a manhole, pump station or plant. Not an outfall listed in a permit.

Source: the operator's own overflow reports to the state. DirtyWaterWatch groups reports within 50 metres into one place and finds the water below it with U.S. Geological Survey river maps (NLDI, NHDPlus). Not a permitted outfall; provisional until an official outfall record exists.

Reports and advisories

Sanitary sewer overflow (SSO): sewage spills from a sewer meant to carry sewage separately from rainwater. Treatment bypass: wastewater skips one or more treatment steps.
