Jump to: navigation, search

The following tables list the organic analytes that water samples are tested for by Environmental Service Laboratories (ESL) for the Project. They are separated into three areas: volatile organic compounds (VOCs), semi-volatile organic compounds (SVOCs), and BTEX compounds. To learn more about how these tests are carried out by ESL, see Analysis of Organics.

  1. ^ a b c Reporting limits are in units of micrograms per Liter, or parts-per-billion. Organic compounds are considered to be present and quantifiable if reported above this limit.
  2. ^ a b m-xylene refers to meta-xylene (aka 1,3-dimethylbenzene) and p-xylene refers to para-xylene (aka 1,4-dimethylbenzene).
  3. ^ a b o-xylene refers to ortho-xylene (aka 1,2-dimethylbenzene).
  4. ^ a b Refers to total amounts ortho-, meta-, and para- xylenes.
  5. ^ a b c d e f g h i j Analyzed in both VOC and SVOC methods.
