Chemical and radiological sample results
MS0610041 , Acl Water Association #2
33 of the 72 analytes this system has been tested for have been detected at least once, across 266 samples on record.
The other 39 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 266 samples on record, detections range from October 20, 2003 to September 22, 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 221–230 of 266 samples, newest first — collected August 9, 2007 to September 10, 2007. The summary above covers all 266.
22 results from the 10 samples listed here: 21 detected, 1 not detected. Across the whole record it is 339 of 1,425. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
