Chemical and radiological sample results

MS0060020 , Town of Winstonville

27 of the 57 analytes this system has been tested for have been detected at least once, across 367 samples on record.

The other 30 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 367 samples on record, detections range from July 27, 1993 to January 14, 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.

Every analyte ever detected for Town of Winstonville, 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 261–270 of 367 samples, newest first — collected July 7, 2008 to June 15, 2009. The summary above covers all 367.

74 results from the 10 samples listed here: 19 detected, 55 not detected. Across the whole record it is 677 of 2,568. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.

Units in this table

Dichloromethane is recorded on this page in ug/l and mg/l. 1 mg/l = 1,000 ug/l.

Chemical and radiological sample results for Town of Winstonville, every result from 261 to 270 of 367 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 May 18, 2009, sampling point MRT000 Total Haloacetic Acids (Haa5) 2456 Apr 1, 2009 – Jun 30, 2009
