Chemical and radiological sample results
MS0590003 , Blackland Water Association
15 of the 56 analytes this system has been tested for have been detected at least once, across 149 samples on record.
The other 41 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 149 samples on record, detections range from August 11, 2004 to August 11, 2025. These figures cover the whole record.
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 71–80 of 149 samples, newest first — collected August 20, 2014 to March 27, 2017. The summary above covers all 149.
37 results from the 10 samples listed here: 6 detected, 31 not detected. Across the whole record it is 155 of 799. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
