1. Reported wastewater outlet

Operator named in the record: GEORGETOWN STP, CITY OF (federal wastewater discharge permit, NPDES, IL0022322). Outlet: 003. Location: 39.47917, -87.62667; location source: given in the source record.

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

Source: EPA ECHO wastewater outlet records, permit IL0022322, outlet 003. Location linked by DirtyWaterWatch.

2. Waters named in the notice

The notice names: “ellis creek”. Not linked to a mapped water. No water placed from the report's own text, and its outfall of IL0022322 (its outfall_id) has no mapped water: outfall 003: the outlet list in EPA and state records gives it no water record (NHD builder: EPA's reaches for it are unnamed in NHDPlus V2.1; no NHD flowline or waterbody of that name in the state; no NHD flowline or waterbody of that name).

3. Estimated downstream stretch

We estimate routes only on rivers before they become tidal. We do not estimate routes through tidal water or lakes.

Map sources: water outlines and launches from OpenBoatLaunch and OpenStreetMap contributors (Open Database License); wastewater outlets from EPA and state records; downstream estimates by DirtyWaterWatch using U.S. Geological Survey maps and flow data. Base map: OpenFreeMap and OpenMapTiles.
