Chemical and radiological sample results

MS0360016 , Westover Water Association, Inc

20 of the 62 analytes this system has been tested for have been detected at least once, across 230 samples on record.

The other 42 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 230 samples on record, detections range from June 27, 2002 to February 24, 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 Westover Water Association, Inc, 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 11–19 of 19 samples, newest first — collected February 5, 2025 to September 3, 2025. The summary above covers all 19.

53 results from the 9 samples listed here: 8 detected, 45 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 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 The location on record identifies a private home, and we do not publish those.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 Westover Water Association, Inc, every result from 11 to 19 of 19 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
