Chemical and radiological sample results
MS0300165 , Gulf LNG Clean Energy Potable Water Plan
15 of the 54 analytes this system has been tested for have been detected at least once, across 129 samples on record.
The other 39 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 129 samples on record, detections range from August 8, 2012 to August 4, 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 34 samples, newest first — collected August 28, 2025 to August 4, 2026. The summary above covers all 34.
14 results from the 10 samples listed here: 8 detected, 6 not detected. Across the whole record it is 140 of 595. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.
