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 271–280 of 362 samples, newest first — collected July 30, 2009 to June 29, 2010. The summary above covers all 362.

83 results from the 10 samples listed here: 45 detected, 37 not detected, 1 with no result recorded. Across the whole record it is 432 of 1,655. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.

  • Total Haloacetic Acids (Haa5) 2456

    Result

    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. What the limit was is not on record. Whether the result was a detection is a separate column: read resultType.
