13 of the 13 analytes this system has been tested for have been detected at least once, across 508 samples on record.
The other 0 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 508 samples on record, detections range from December 8, 1993 to September 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 451–460 of 508 samples, newest first — collected June 14, 1995 to June 11, 1996. The summary above covers all 508.
20 results from the 10 samples listed here: 17 detected, 3 not detected. Across the whole record it is 1,154 of 1,313. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
