Chemical and radiological sample results
MS0150006 , Harmony Ridge Water Assn
24 of the 58 analytes this system has been tested for have been detected at least once, across 237 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 237 samples on record, detections range from September 8, 1993 to September 16, 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.

The most recent samples, result by result
The table below lists 51–60 of 237 samples, newest first — collected July 29, 2019 to April 20, 2021. The summary above covers all 237.
42 results from the 10 samples listed here: 9 detected, 33 not detected. Across the whole record it is 255 of 874. 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
Sodium is recorded on this page in ug/l and mg/l. 1 mg/l = 1,000 ug/l.
