Chemical and radiological sample results

MS0540063 , Sardis Lake Community W/A

18 of the 56 analytes this system has been tested for have been detected at least once, across 256 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 256 samples on record, detections range from October 13, 2003 to July 15, 2026. These figures cover the whole record; the list of samples further down is narrowed.

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 Sardis Lake Community W/A, 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 1–10 of 21 samples, newest first — collected September 22, 2025 to July 15, 2026. The summary above covers all 21.

92 results from the 10 samples listed here: 7 detected, 85 not detected. Across the whole record it is 173 of 1,568. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.

We withheld the location of 2 sampling points below. The location on record identifies a private home, and we do not publish those. That is our decision, not the agency’s. The sampling point, its type and every result taken there are published unchanged.

Chemical and radiological sample results for Sardis Lake Community W/A, every result from 1 to 10 of 21 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
