Coliform and microbial samples
MS0370001 , Arnold Line Water Association
9 of 2,568 results on record were positive for coliform or another organism the agency tests for. The most recent was January 13, 2025.
They fall across 9 of the 1,950 samples on record.
Every sample on record, October 15, 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.
Choose a date range
The list below shows 136–150 of 167 samples in this date range, newest first.
Routine (11), 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.
