Coliform and microbial samples
MS0490023 , Hays Creek W/A-Minerva #2
3 of 389 results on record were positive for coliform or another organism the agency tests for. The most recent was April 7, 2025.
They fall across 3 of the 289 samples on record.
Every sample on record, October 8, 2003 to August 4, 2026. These figures cover the whole record; the list of samples further down is narrowed.
The most recent samples
Showing samples collected between September 26, 2024 and September 26, 2026. That is this page’s default, not a limit on what the agency records.
Choose a date range
The list below shows 16–27 of 27 samples in this date range, newest first.
Routine (8), Repeat (3) and TG (1). The agency publishes no name for the code TG, so none is shown — this page does not invent labels the agency has not published.
