Chemical and radiological sample results
MS0020014 , Prentiss-Alcorn Water Assn
21 of the 57 analytes this system has been tested for have been detected at least once, across 251 samples on record.
The other 36 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 251 samples on record, detections range from November 3, 1993 to August 12, 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 101–110 of 251 samples, newest first — collected January 17, 2012 to January 22, 2014. The summary above covers all 251.
28 results from the 10 samples listed here: 6 detected, 22 not detected. Across the whole record it is 258 of 983. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
