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 171–180 of 243 samples, newest first — collected July 25, 2007 to April 26, 2010. The summary above covers all 243.

42 results from the 10 samples listed here: 22 detected, 20 not detected. Across the whole record it is 301 of 1,021. A sample is analysed for many analytes at once, so one sample appears on as many rows as it had results.

  • Calcium 1016 EPA method 200.8

    Result

    6.78 mg/l 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.

  • Alkalinity, Caco3 Stability 1067 EPA method 2320B

    Result

    0 mg/l This result is recorded as a detection, and the figure the agency wrote — "0" — 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.
