Chemical and radiological sample results
MS0400009 , Thomastown Water Association
42 of the 73 analytes this system has been tested for have been detected at least once, across 257 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 257 samples on record, detections range from October 1, 2003 to December 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.

The most recent samples, result by result
The table below lists 221–230 of 257 samples, newest first — collected March 23, 2006 to June 28, 2007. The summary above covers all 257.
30 results from the 10 samples listed here: 13 detected, 17 not detected. Across the whole record it is 275 of 2,205. 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
TTHM is recorded on this page in ug/l and mg/l. 1 mg/l = 1,000 ug/l.
