Chemical and radiological sample results

MS0150021 , Hood Scout Reservation

3 of the 3 analytes this system has been tested for have been detected at least once, across 19 samples on record.

The other 0 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 19 samples on record, detections range from November 28, 2006 to March 21, 2016. 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.

Every analyte ever detected for Hood Scout Reservation, with how many results found it and when it was first and last detected. Covers the whole record, not only the samples listed below.
Analyte Kind Detected in First detected Last detected
Nitrate-Nitrite 1038 Inorganic Chemical 2 of 19 results Nov 28, 2006 Mar 21, 2016
Nitrate 1040 Inorganic Chemical 2 of 19 results Nov 28, 2006 Mar 21, 2016
Nitrite 1041 Inorganic Chemical 1 of 19 results Mar 21, 2016 Mar 21, 2016

The most recent samples, result by result

The table below lists 1–10 of 19 samples, newest first — collected November 19, 2014 to February 6, 2025. The summary above covers all 19.

30 results from the 10 samples listed here: 3 detected, 27 not detected. Across the whole record it is 5 of 57. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.

Chemical and radiological sample results for Hood Scout Reservation, every result from 1 to 10 of 19 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.
