Chemical and radiological sample results

MS0340017 , Shady Grove Utility District

24 of the 57 analytes this system has been tested for have been detected at least once, across 350 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 350 samples on record, detections range from September 24, 2003 to April 1, 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.

Every analyte ever detected for Shady Grove Utility District, with how many results found it and when it was first and last detected. Covers the whole record, not only the samples listed below.

The most recent samples, result by result

The table below lists 101–110 of 350 samples, newest first — collected October 28, 2019 to June 29, 2020. The summary above covers all 350.

35 results from the 10 samples listed here: 11 detected, 24 not detected. Across the whole record it is 304 of 2,031. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.

Chemical and radiological sample results for Shady Grove Utility District, every result from 101 to 110 of 350 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
