Chemical and radiological sample results

MS0550061 , PRCUA-Poplarville Water System

24 of the 61 analytes this system has been tested for have been detected at least once, across 62 samples on record.

The other 37 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 62 samples on record, detections range from October 16, 2008 to March 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.

Every analyte ever detected for PRCUA-Poplarville Water System, 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 62 samples, newest first — collected March 6, 2023 to September 29, 2025. The summary above covers all 62.

26 results from the 10 samples listed here: 3 detected, 23 not detected. Across the whole record it is 45 of 605. 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 The location on record identifies a private home, and we do not publish those.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 PRCUA-Poplarville Water System, every result from 1 to 10 of 62 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
