Analytes tested for
MS0240263 , West Harrison High School
West Harrison High School has been analysed for 67 analytes.
This is what has been looked for, not what has been found. Which of them have been detected, and when, is on the sample results page.
The agency also publishes one analyte list across every system it serves. That list carries no results and no counts, and it leaves out coliform and the other microbiological analytes — which this page does not.
65 of these are chemical, radiological or water-quality analytes, and their results are on the chemical and radiological samples page — which counts 65, not 67, for that reason. The other 2 — Coliform (TCR) and E. Coli — are organisms, and their records live with the coliform and microbial samples.

A result is one laboratory analysis for one analyte on one sample, whether or not anything was found. Counts cover every Accepted or Validated result on record, with no date range applied.
What an analyte is
“Analytes are contaminants and other elements (some of which are not necessarily contaminants), for which the drinking water is being analyzed.”
