1. Reported wastewater outlet

Operator named in the record: Whittier City (federal wastewater discharge permit, NPDES, 4SSO10443). Outlet: “[house number removed] Rideout Pl”. Location: 33.99727, -118.04707; location source: given in the source record.

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

2. Waters named in the notice

The notice names no water. No receiving water: the report says the discharge did not reach a water. The report is kept here but is not placed on a water and colours none on the map.

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.
