Chemical and radiological sample results

MS0820028 , Midway W/A #3

34 of the 71 analytes this system has been tested for have been detected at least once, across 291 samples on record.

The other 37 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 291 samples on record, detections range from November 5, 2003 to April 22, 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.

Every analyte ever detected for Midway W/A #3, with how many results found it and when it was first and last detected. Covers the whole record, not only the samples listed below.

The most recent samples, result by result

The table below lists 231–240 of 291 samples, newest first — collected May 11, 2009 to August 10, 2009. The summary above covers all 291.

53 results from the 10 samples listed here: 26 detected, 27 not detected. Across the whole record it is 535 of 1,157. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.

We withheld the location of 2 sampling points below. The location on record identifies a private home, and we do not publish those. That is our decision, not the agency’s. The sampling point, its type and every result taken there are published unchanged.

Chemical and radiological sample results for Midway W/A #3, every result from 231 to 240 of 291 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.

0 mg/l This result is recorded as a detection, and the figure the agency wrote — "0.00" — is zero to the precision it was written to. Read the zero as "smaller than the written figure resolves", not as "none present". SDWIS holds a separate numeric concentration that Drinking Water Watch does not publish, so this endpoint does not carry it either; no more precise magnitude is available here. , sample collected Jul 27, 2009, sampling point MRT000 Total Haloacetic Acids (Haa5) 2456 Jul 1, 2009 – Sep 30, 2009
