Chemical and radiological sample results
MS0490006 , North District 1 Water Assn.
21 of the 55 analytes this system has been tested for have been detected at least once, across 357 samples on record.
The other 34 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 357 samples on record, detections range from May 24, 2004 to June 23, 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.

The most recent samples, result by result
The table below lists 331–340 of 357 samples, newest first — collected July 28, 2008 to August 7, 2008. The summary above covers all 357.
21 results from the 10 samples listed here: 17 detected, 4 not detected. Across the whole record it is 558 of 1,045. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
