Chemical and radiological sample results
MS0810009 , Tillatoba Water Association
40 of the 71 analytes this system has been tested for have been detected at least once, across 241 samples on record.
The other 31 were tested for and never found. An analyte is counted here if any result on record measured it, so this covers the whole history and not the samples listed below.
Across all 241 samples on record, detections range from November 3, 2003 to June 22, 2026. These figures cover the whole record; the list of samples further down is narrowed.
What counts as a non-detect is defined in the help: Less than Indicator. This system’s violations.
What has been detected, ever
Every analyte measured above its reporting level at any point in this system’s record, most often detected first. This is not limited to the samples listed below.

The most recent samples, result by result
The table below lists 1–10 of 17 samples, newest first — collected April 14, 2025 to June 22, 2026. The summary above covers all 17.
36 results from the 10 samples listed here: 25 detected, 11 not detected. Across the whole record it is 426 of 1,297. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
We withheld the location of 2 sampling points below. The location on record identifies a private home, and we do not publish those. That is our decision, not the agency’s. The sampling point, its type and every result taken there are published unchanged.
