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.

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 121–130 of 230 samples, newest first — collected July 12, 2012 to April 9, 2014. The summary above covers all 230.

34 results from the 10 samples listed here: 15 detected, 19 not detected. Across the whole record it is 273 of 1,315. 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 Westover Water Association, Inc, every result from 121 to 130 of 230 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
