Chemical and radiological sample results

MS0360010 , Lafayette Springs Water Assn

24 of the 57 analytes this system has been tested for have been detected at least once, across 283 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 283 samples on record, detections range from November 12, 2003 to March 3, 2025. 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 Lafayette Springs Water Assn, 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 11–14 of 14 samples, newest first — collected February 2, 2025 to February 10, 2025. The summary above covers all 14.

4 results from the 4 samples listed here: 3 detected, 1 not detected. 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 1 sampling point 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 The location on record identifies a private home, and we do not publish those.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 Lafayette Springs Water Assn, every result from 11 to 14 of 14 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
