Chemical and radiological sample results
MS0150003 , Crystal Springs Water Service
31 of the 110 analytes this system has been tested for have been detected at least once, across 472 samples on record.
The other 79 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 472 samples on record, detections range from July 14, 1992 to February 17, 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 91–100 of 472 samples, newest first — collected July 18, 2018 to September 27, 2018. The summary above covers all 472.
27 results from the 10 samples listed here: 13 detected, 14 not detected. Across the whole record it is 431 of 1,515. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
