Chemical and radiological sample results

MS0750005 , Hilldale Water District

43 of the 74 analytes this system has been tested for have been detected at least once, across 389 samples on record.

The other 31 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 389 samples on record, detections range from October 29, 2003 to July 21, 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 Hilldale Water District, 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 381–389 of 389 samples, newest first — collected October 29, 2003 to June 10, 2004. The summary above covers all 389.

93 results from the 9 samples listed here: 19 detected, 74 not detected. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.

Units in this table

Ethylbenzene is recorded on this page in ug/l and mg/l. 1 mg/l = 1,000 ug/l.

Toluene is recorded on this page in ug/l and mg/l. 1 mg/l = 1,000 ug/l.

Chemical and radiological sample results for Hilldale Water District, every result from 381 to 389 of 389 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
