Chemical and radiological sample results
MS0380005 , City of Meridian
29 of the 59 analytes this system has been tested for have been detected at least once, across 492 samples on record.
The other 30 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 492 samples on record, detections range from August 6, 2002 to August 11, 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 411–420 of 492 samples, newest first — collected March 6, 2006 to November 16, 2006. The summary above covers all 492.
22 results from the 10 samples listed here: 13 detected, 9 not detected. Across the whole record it is 609 of 1,666. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.

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