Chemical and radiological sample results

MS0240251 , Ridgecrest Estates

36 of the 72 analytes this system has been tested for have been detected at least once, across 156 samples on record.

The other 36 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 156 samples on record, detections range from December 12, 2000 to February 11, 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 Ridgecrest Estates, 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 31–40 of 156 samples, newest first — collected July 18, 2018 to September 17, 2019. The summary above covers all 156.

51 results from the 10 samples listed here: 10 detected, 41 not detected. Across the whole record it is 177 of 892. 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 Ridgecrest Estates, every result from 31 to 40 of 156 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
