Chemical and radiological sample results
MS0650013 , White Oak Water Association
42 of the 74 analytes this system has been tested for have been detected at least once, across 273 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 273 samples on record, detections range from October 27, 2003 to July 1, 2026. These figures cover the whole record; the list of samples further down is narrowed.
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 1–10 of 20 samples, newest first — collected April 8, 2025 to July 20, 2026. The summary above covers all 20.
90 results from the 10 samples listed here: 29 detected, 61 not detected. Across the whole record it is 355 of 1,646. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
