Coliform and microbial samples
MS0240005 , City of Long Beach
26 of 5,076 results on record were positive for coliform or another organism the agency tests for. The most recent was August 7, 2025.
They fall across 26 of the 4,951 samples on record.
Every sample on record, October 7, 2003 to August 5, 2026. These figures cover the whole record; the list of samples further down is narrowed.
The most recent samples
Showing samples collected between September 27, 2024 and September 27, 2026. That is this page’s default, not a limit on what the agency records.

The list below shows 241–255 of 489 samples in this date range, newest first.
TG (6), Routine (6) and Repeat (3). The agency publishes no name for the code TG, so none is shown — this page does not invent labels the agency has not published.
