Chemical and radiological sample results

MS0490018 , Hays Creek W/A-Legion Lake Rd

11 of the 13 analytes this system has been tested for have been detected at least once, across 89 samples on record.

The other 2 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 89 samples on record, detections range from July 19, 2004 to July 8, 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 Hays Creek W/A-Legion Lake Rd, 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 61–70 of 89 samples, newest first — collected June 27, 2011 to August 4, 2014. The summary above covers all 89.

41 results from the 10 samples listed here: 20 detected, 21 not detected. Across the whole record it is 140 of 214. 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 Hays Creek W/A-Legion Lake Rd, every result from 61 to 70 of 89 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
