Chemical and radiological sample results
MS0590018 , New Site Water Association
32 of the 70 analytes this system has been tested for have been detected at least once, across 154 samples on record.
The other 38 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 154 samples on record, detections range from October 20, 2003 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 81–90 of 154 samples, newest first — collected July 16, 2012 to August 19, 2014. The summary above covers all 154.
39 results from the 10 samples listed here: 5 detected, 34 not detected. Across the whole record it is 183 of 786. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
