Coliform and microbial samples
MS0700003 , Chalybeate Water Assn
10 of 790 results on record were positive for coliform or another organism the agency tests for. The most recent was June 22, 2026.
They fall across 9 of the 590 samples on record.
Every sample on record, October 6, 2003 to July 22, 2026. These figures cover the whole record; the list of samples further down is narrowed.
The most recent samples
Showing samples collected between September 25, 2024 and September 25, 2026. That is this page’s default, not a limit on what the agency records.
Choose a date range
The list below shows 1–15 of 57 samples in this date range, newest first.
Routine (9), TG (3) 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.
