Chemical and radiological sample results

MS0560003 , N E Perry Utl Assn-#1

27 of the 58 analytes this system has been tested for have been detected at least once, across 263 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 263 samples on record, detections range from October 15, 2003 to August 13, 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 N E Perry Utl Assn-#1, 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 261–263 of 263 samples, newest first — collected October 15, 2003 to February 23, 2004. The summary above covers all 263.

34 results from the 3 samples listed here: 2 detected, 32 not detected. 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 N E Perry Utl Assn-#1, every result from 261 to 263 of 263 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
