Chemical and radiological sample results

MS0550058 , Pearl River Central W/A-Bi Co

41 of the 74 analytes this system has been tested for have been detected at least once, across 310 samples on record.

The other 33 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 310 samples on record, detections range from October 15, 2003 to July 23, 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 Pearl River Central W/A-Bi Co, 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 310 samples, newest first — collected August 3, 2006 to May 13, 2009. The summary above covers all 310.

50 results from the 10 samples listed here: 23 detected, 27 not detected. Across the whole record it is 391 of 1,810. 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 Pearl River Central W/A-Bi Co, every result from 261 to 270 of 310 samples shown, newest first. Not detected means the amount was below the level the laboratory can reliably report, which is given beside it.

0 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. The agency recorded a value but no unit of measure for it. The unit is NOT inferable from the analyte: many analytes are reported in more than one unit — TTHM and HAA5 in both MG/L and UG/L — so there is no per-analyte default to fall back on. The number is published as it stands and must not be compared to a limit. The agency recorded which kind of limit this result was below, but stored 0.000000000 as the limit itself, which is not a level. The type is published and the value is null.
