Chemical and radiological sample results
MS0450019 , PRVWSD-Main Harbor
23 of the 56 analytes this system has been tested for have been detected at least once, across 224 samples on record.
The other 33 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 224 samples on record, detections range from October 6, 2003 to February 12, 2026. 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 141–150 of 224 samples, newest first — collected August 9, 2011 to February 9, 2012. The summary above covers all 224.
24 results from the 10 samples listed here: 11 detected, 13 not detected. Across the whole record it is 298 of 1,023. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
