Chemical and radiological sample results

MS0760010 , Winterville Water Association

36 of the 73 analytes this system has been tested for have been detected at least once, across 150 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 150 samples on record, detections range from November 3, 2003 to August 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 Winterville Water Association, with how many results found it and when it was first and last detected. Covers the whole record, not only the samples listed below.

No date range is applied: this list draws on every sample on record. Show the last two years only.

The most recent samples, result by result

The table below lists 41–50 of 150 samples, newest first — collected September 7, 2016 to April 9, 2018. The summary above covers all 150.

50 results from the 10 samples listed here: 15 detected, 35 not detected. Across the whole record it is 233 of 576. 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 Winterville Water Association, every result from 41 to 50 of 150 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
