Chemical and radiological sample results
MS0270007 , Town of Silver City
40 of the 72 analytes this system has been tested for have been detected at least once, across 275 samples on record.
The other 32 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 275 samples on record, detections range from July 29, 1993 to February 24, 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 271–275 of 275 samples, newest first — collected July 29, 1993 to July 29, 1993. The summary above covers all 275.
10 results from the 5 samples listed here: 4 detected, 6 not detected. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
