Chemical and radiological sample results
MS0560015 , Little Creek Water Association
35 of the 72 analytes this system has been tested for have been detected at least once, across 184 samples on record.
The other 37 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 184 samples on record, detections range from November 3, 2003 to March 18, 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 184 samples, newest first — collected February 14, 2012 to July 18, 2012. The summary above covers all 184.
27 results from the 10 samples listed here: 5 detected, 22 not detected. Across the whole record it is 231 of 991. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
